plain english

you have reverted to an earlier version and removed a lot of information recently added.

Why cant you write this in plain english? phrases like

'Further finds at Afar, including the many hominid bones in "site 333", produced more bones of concurrent date, and led to Johanson and White's eventual argument that the Koobi Fora hominids were concurrent with the Afar hominids.'

is pompous and difficult to understand. Better to write

' Johanson and White found further bones dated around the same time as the previous finds at 'Site 333', and they now believe that the hominids at Koobi Fari were alive the same time as the Afar hominids'

If your going to write science, you need to write it in a way that the average person can understand. peppering the text with long latinised words and obscure grammar just drives people away from reading the rest and is elitist. Please write in plain english for the average person. Dont dumb it down, just dont use 20 long latin words when 5 anglo-saxon ones say the same thing.

Please sign your comments with ~~~~ So that everyone knows who you are. As you can see by the edit diff, I did not touch the paragraph you are complaining about. What I did do was remove or modify language that repeats already given informaiton or that talks directly to the reader. This isn't a science magazine, this is an encyclopedia. - UtherSRG 12:32, Mar 7, 2005 (UTC)

Thats as may be, but you still need to make it readable. The sort of person that looks this sort of articlein an encyclopedia may not have a scientific background. No point in an encyclopedia if no one reads it cos its unitelligble to anyone with an IQ less than 150. Do we want to make wikpedia used by all or just by a few over educated elitist snobs ? Better that its read by all , surely!!! In which case, write plain english!!!

193.131.115.253

Something that isn't plain English is that this article states the name Lucy comes from the Beatles whereas Lucy Maud Montgomery (a random example) was born in 1874, where the name Lucy appeared much earlier in history. For the sake of pedantry can this section be reworded to reflect that "Lucy's naming comes from..."? AsparagusTips (talk) 16:52, 25 May 2020 (UTC)Reply

Good Pic of Afarensis Skeleton!!!

Please I advise no one else to change Lucy's skeleton pic, this one is better than that old foggy one before. I didn't place that pic but I thank the person who changed it.

that's my first picture to be placed in the wiki! took it on my trip to mexico, you're very welcome!!! :) --Danrha 17:24, 27 November 2005 (UTC)Reply

subtitel of the first picture correct?

I was wondering whether the subtitle under the picture of the original remainings of Lucy is correct. How come that they are in Mexico, whereas the text states that they are preserved in Addis Abeba. The latter would be more comprehensible, since it was found in Ethopia. (A1977 20:19, 27 March 2006 (UTC))Reply

I have investigated and i apologize for my mistake, the skeleton from the picture is a replica... although i was misinformed in the exposition. --Danrha 15:40, 29 April 2006 (UTC)

Aramis, Ethiopia?

I was surprised to see this as a live link in the article because I've been working on Ethiopian geography articles, & I've never heard of this place before. So I assumed that I learned something new today, & followed the link. Which led me to an article about a fictional character from The Thee Musketeers -- but there was a link in that article to a disambiguation page, so I followed that one. Which did not include an "Aramis, Ethiopia".

Could the person responsible for that fact please check her/his notes & assure me that the link is spelled correctly (or close enough to how it sounds)? Once that is done, I could start the process of checking my notes & try to write an article for it. -- llywrch 22:35, 3 May 2006 (UTC)Reply

Neutrality

Acording to the resources listed, nearly all of them come from people who very biased towards evolution. Evolution hasn't been proven, and intelligent design hasn't been disproven. I think it would be unfair to simply state all of this information as fact when it hasn't been proven beyond a shadow of a doubt. Many scientists still hold that this "missing link" is nothing more than an extinct form of primate, not a common ancestor for mankind. Wouldn't it do more justice to science to at least make a small note or something that the information in this page isn't accepted by all of the scientific community and give a brief description from a intelligent design perspective, or at least make a note that further testing is needed before it can be said with absolute certainty to be true?

Yes and the article on human embryology is resourced by people who have a bias against the "Stork Theory" of human reproduction. Its completely unfair that this article be biased towards data, facts, logic, scientific consensus and application. In fairness articles should include every superstition and psuedoscientific fantasies like creationism.

I think it's standard practice for encyclopedia's to assume evolution is true. I believe this is done because articles are usually written by "experts" in that particular field. And the experts (biologists) believe that the evidence for evolution is more than adequate to merit general (if not universal and unequivocal) acceptance. Go figure. Miguel Chavez 20:19, 27 May 2006 (UTC))Reply
The vast majority of scientists studying A. afarensis see the species as an ancestor of Homo spp. If you can provide legitimate, scholarly, peer-reviewed sources that show that some researchers disagree with this view, then perhaps those sources should be added, either to this article or to the transitional fossil article. I would argue, however, that the study of A. afarensis is something that can only be conducted using the scientific method, and since intelligent design inherently precludes the use of the scientific method, to discuss intelligent design on this page would be the equivalent of discussing scientific proof for the existence of Daffy Duck in that entry.

Creationism-lite, or Intelligent Design, is poor science. And the only people who doubt evolution are people who don't like the idea that man descended from more primitive species. If Biblical Creationism is to be taught alongside evolution, then should Navajo Creationism, Islamic Creationism, Egyptian Creationism, Norse Creationism, etc. 199.76.152.229 02:43, 2 December 2007 (UTC)Reply

"Australopithecus afarensis is an extinct hominid which lived between 3.9 and 2.9 million years ago." This is a statement of fact. A "fact" is a piece of knowledge which is undisputably proven to true through solid evidence (i.e. multiple witnesses, reliable contemporary documentation, objective analysis, etc.) Unless undisputable proof of a 3 million year old age can be found it's still "best guess." I have yet to find an objective analysis of the method used[1]. I haven't found one that doesn't either assume it is accurate or vise versa. At the minimum it is contraversial and as such it should be noted.—Preceding unsigned comment added by Historiocality (talkcontribs) 22:31, 6 July 2007

It is a matter of scientific fact, as defined by the overwhelming majority of the scientific community. It is subject to religious dispute involving pseudoscience.

To state that something is millions of years old, one must have a lot of evidence. There was a story of a group of scientists who studied a fossilized foot and dated it millions of years old...they then found out that it was discovered inside a cowboy boot.
This claim is completely false, as you would have found if you had taken even the 2 seconds of googling it requires to find out. Some creationists (Carl Baugh and Don Patton) have touted that a cowboy boot filled with some hardened material and some bones is a fossilized human foot. (They give no plausible explanation for how the bones and skin inside the boot could become fossilized while the boot itself did not. It's overwhelmingly likely that the bone is not fossilized, just surrounded by sedimentary rock.) No scientists ever dated it and were surprised it came from a boot. How could they? It's not been taken out of the boot! And the methods scientists use to date very old fossils rely on dating the rocks around the fossil, not the fossil itself. There is lots of evidence that lucy's bones and the fossils of numerous other creatures are millions of years old, and radiometric dating has been verified with many other independent dating methods such as dendrochronology, varve chronology, coral growth patterns, etc. Scientific articles should be based on science, not second-hand misremembered stories creationists have heard and never bothered to verify. — Preceding unsigned comment added by 184.99.225.95 (talk) 17:49, 27 July 2012 (UTC)Reply

I also am more inclined to believe in intelligent design based on the significant amount of data supporting it. But because we obviously have no way of knowing exactly what happened at the beginning of the earth, we must base our beliefs on what evidence we can find. --Watchout4snakes!

Who discovered Lucy

Small technical point. Didn't Lucy catch Johanson's eye. His book Lucy portrays it that way, "I noticed something lying on the ground..." (p. 16) and I doubt they saw it at the same time. Also, his book says they discovered the fossil remains on Nov. 30th, not the 24th (p. 13). Am I missing something? Can anyone confirm or refute my understanding of the facts. This would be much appreciated. I am a stickler for the details, and it bothers me still when I hear that it was Louis that discovered Zinjanthropus. Miguel Chavez 20:13, 27 March 2006 (UTC))Reply

Several changes

I have removed the reference to Lucy's discovery in the opening paragraph. The emphasis in the opening paragraph should be on the species that the article is about, not on a single discovery. It seems to me that the placement of importance on Lucy's discovery in the opening paragraph has only been done because this article is part of 'WikiProject Ethiopia'. Let's not bias our articles towards certain countries.

I removed a short sentence that tells us that Australopithecus afarensis belongs to the genus Australopithecus, which I think will be obvious to the reader.

'There are differing views on how Lucy or her ancestors first became bipedal full-time.' It is not universally agreed upon that A. afarensis did move on two legs all the time. Indeed, the article goes on to say 'In fact these hominines may have occasionally walked upright but still walked on all fours'. I have ammended this.

My 2004 copy of The Cambridge Encyclopedia of Human Evolution puts the known date of A. afarensis at >4 to 2.5 millions of years ago. This is somewhat different to 3.9 to 3 million years ago in this article. User:Paul_P —The preceding unsigned comment was added by 82.46.196.230 (talkcontribs) .

I agree about the emphasis on the species. I have been working on creating pages for major finds. Does anyone object to me breaking Lucy out onto her own page? I mean we have pages for Taung Child and Mrs. Ples. I think Lucy is just as deserving. And when we have individual pages for the finds, we can add a lot more detailed pictures and info about the fossil itself and why it is significant. Nowimnthing 23:40, 17 August 2006 (UTC)Reply

More Changes

As referred to just above, I have removed reference to the Aquatic Ape theory (recently re-inserted). Whether a valid theory or not, it is not relevent to a specific entry on one particular hominin taxon such as A. afarensis. If it is to be discussed/debated, this should happen either on the Aquatic ape hypothesis page, or on more general pages on human origins. AAH enthusiasts, I request that you adhere to the spirit of this request and note that I have also removed general discussion of the savanna hypothesis from this entry as well (see bipedalism for further discussion). I feel that taxon specific pages should not discuss too deeply broader evolutionary theories, but should stay focussed on that taxon alone.

While keeping it impartial to the differing academic views on A. afarensis locomotion, I have tightened up the English in the bipedalism section, and added some information on shoulder joint orientation, and pelvic and lower limb morphology. I've edited and retitled the "brain size" section to reflect a short but more general section on craniodental morphology as well as brain size. I also changed the section on Social Behaviour, making it more reflective of the consensus view of this issue.Ucgaweh 04:23, 27 September 2006 (UTC)Reply

I added a bit to the bipedalism section based on criticisms of the part-time arboreal hypothesis that I think ultimately go back to Owen Lovejoy. Unfortunately I have no citation beyond "I learned it my Paleontology class from a Lovejoy fan".

I'm a creationist, and I also see no derision in this article. it does, however, promote one particular interpretation of the data, namely the Darwinian theory of evolution. Though, I can't agree with UtherSRG that there are no assumptions made. When dealing with the unobservable past, one has to make assumptions. Many assumptions are made here, as well as in many articles that deal with the remote past -- assumptions based on the presupposition that Darwinian evolution is true. A creationist working with the same data, can easily interpret the data to fit into the model of supernatural creation. The difference isn't the data. The difference stems from the interpretation of the data -- an interpretation which is influenced by your individually held world view. User:Hexc0de Friday, 2007-02-23 T 01:52 UTC.

See NPOV: Making necessary assumptions .. dave souza, talk 08:18, 19 October 2007 (UTC)Reply

  • OK, so that makes sense. I can respect a person's decision, but shouldn't we go with the most logical assumption? "Lucy" is actually a great example of how many assumptions are made with macroevolutionists. I would think that at least instead of presenting the information as facts (as the article clearly presented) that it should state the theory of evolution as it is, and that is an unconfirmed hypothesis. --Watchout4snakes!

Reverted name of section to "Current Debate"

Contrary to Gamekeeper's last edit summary, the title "Current Debate" is clearer, and does not necessarily reflect any creationist bias. Scientists Yoel Rak, Avishag Ginzburg, and Eli Geffen are not "creationist" scientists.

Hi I don't think 'current debate' is a a good title as it does not give any information as to what the current debate is about. I prefer Lineage Question or even more simply Lineage , which should follow after the physical characteristics section as lineage arguments tend to rely on the physical characteristics. I would like to see the subject of Lineage expanded, as this is the reason for much interest in this topic.
On a separate note: the research referenced is used by a lot of creationist websites to cast doubt on evolutionist theories. Some misrepresent the data as showing that this is descended from Gorilla's which is not what the research shows, they also link this to Lucy whereas the jaw bone in question was not Lucy's. I don't think this research should be excluded because of its interest to creationist quite the contrary, as long as it is represented factually. GameKeeper 09:44, 19 October 2007 (UTC)Reply
Thanks Dave for filling out the lineage section. I have altered it slightly as the paper here does not conclude that the Australopithecus afarensis could be a gorilla ancestor, just that the shape of the jaw had followed a path of Parallel evolution. This is a precursor to the evolution of the 'robust' brunch of the Hominina sub-tribe and as humans are part of the 'gracile' branch means that 'Australopithecus afarensis' is not a common ancestor of modern man. GameKeeper 16:57, 19 October 2007 (UTC)Reply
Thanks, that was something I'd picked up incorrectly in skim reading the same paper. It looks as though the jaw bone was from found near the first family site though found much later, and other fossils from various sites had similar morphology. Now what we need is more info on Ardipithecus ramidus, and probably a correction to the "Related work" section which says it was "contemporaneous with Australopithecus afarensis" – if I've read the paper correctly it was about a million years earlier, perhaps there was an overlap. Also, the Tim White article didn't seem to mention Lucy, must try to fix that sometime. .. dave souza, talk 19:05, 19 October 2007 (UTC) got mixed up, the original link to the comparison photos showed a First Family site fossil, the specimen discovered in 2002, A. L. 822-1 which closely matches that of the gorilla was found in the Unda Hadar, a tributary of the Awash River running parallel to the Kada Hadar, 2.5 km east of A. L. 288 (Lucy's site)... dave souza, talk 21:59, 19 October 2007 (UTC)Reply
After thinking about this for a while I have removed the discussion of this from the summary as 1) This is primary source info 2) A single piece of evidence like this is not enough to be considered conclusive. 3) The conslusion of the paper just suggest this casts doubt, it certainly should not be seen as conclusive. ('casts doubt on the postulated role of Au. afarensis as the common ancestor of later hominins')

Why no distinction between AL288 and AL822? Do we think it's a typo?

"Lineage questions" and 2006 study of finds in 2002 (nowhere tabulated!) completely change the theorized branching of the human tree. This is sourced in one reference, but it changes completely the thinking of the 1974 finds. Why no comparison of tree illustrations, or discussion in depth? Is this reasonable scientific disagreement too subject to attack by the politically charged creationists? Or, are we just too disappointed we have had to abandon our discoveries as not on our direct ancestor tree? I would think a well-reasoned explanation would diminish the noise from dogmatics, by demonstrating how science revises its conclusions... SalineBrain (talk) 09:36, 14 October 2008 (UTC)Reply

Sorry for the late reply. It is an exageration to say the conclusions in Lineage questions about AL288 & AL822 completely change the human tree. Basically around 4-5 million years ago the species that had evolved from the Pan (chimp) common ancestor with Homo (man) branched into 2 separate groups. The robust hominids (with gorilla like jawbones, but NOT closely related to gorillas), and the gracile hominids. We know these branches existed due to later fossil finds. The Homo branch , which we belong to, evolved from the gracile hominids. It was originially thought Lucy and the Australopithecus afarensis lived before the split occured between the graciles and the robusts and were ancestral to both, however the jawbone analysis suggests that actually Lucy and brethern had already split and were only ancestral to the robusts, hence AL822 a possibly older fossil is a more likely candidate for a ancestor of both the robusts and the graciles.
To move the Australopithecus afarensis to being ancestral to only the robusts on the human family tree is not a big change. It only means the split took place slightly earlier than originally thought (perhaps around 5 mya) and does not change the 'family tree' at all, just Australopithecus afarensis location on it.
I've seen the research regarding AL822 misrepresented to suggest that humans are actually more closely related to Gorillas, which is a misunderstanding of the research. Gorilla-like is used in the context of the research because the Robusts were more 'Gorilla-like' than other hominids due to convergent evolution, but were still more closely related to humans (homo) and chimps (pan) that gorillas.
I've tried to update the article to make this clearer. I would like to remove the statement 'Gorilla-like' altghough in the original research because without context it can lead to the wrong conclusions. In my opinion within the article 'Robust-like' would be better. GameKeeper (talk) 22:31, 1 April 2009 (UTC)Reply
I vote for Robust, we even have a page that fairly clearly describes what that means in morphology. Nowimnthing (talk) 15:55, 2 April 2009 (UTC)Reply
Concensus of 2, so I have removed the gorilla reference. I think the description is now clearer. GameKeeper (talk) 22:30, 2 April 2009 (UTC)Reply
AL 288 is the famous Lucy but AL 822 is a very well preserved Skull there is no typo there. GameKeeper (talk) 22:52, 2 April 2009 (UTC)Reply
The lead statement "From analysis it has been thought that A. afarensis was ancestral to both the genus Australopithecus and the genus Homo, which includes the modern human species, Homo sapiens.[1][2]." doesn't mention the current status of this thinking, and presumably a qualification should be added, like "but a more recent find has been interpreted as showing it was more likely an ancestor of only the robust australopithecines branch of the hominid evolutionary tree."
