The Analysis of Ardipithecus ramidus -- One of the Earliest Known Hominids
More than a million-years older than "Lucy," Ardipithecus ramidus and the associated fossils provide the most detailed snapshot of early hominid life. This video features interviews with Project Co-Director Tim White (University of California, Berkeley), Science correspondent Ann Gibbons, and paleoanthropologist Andrew Hill (Yale University). Produced by Robert Frederick and Michael Torrice.

Great video. And thanks to Science magazine for making the 11 Ardipithecus research papers freely available. I just finished reading them - really magnificent work.
Reading this in 2021, because I’m curious to know the true scientific explanation behind human evolution. Thanks 👍🏽
awesome! got to see the faces of all the authors I've been citing for the past week!
I wonder why this isn’t more popular.
Food scarcity seems the likely driver. The mechanism may have been more sophisticated use of sticks and stones along with increasing defensive collaboration.
Awesome! Very thorough explanation, and paints the picture of how life was for Ardi.
@OriginalYTName OH YEAH! it's freaking awesome! I LOOVE IT! it's my life =D Is it going to be Bio Anthro with Archaeology? If so, that's definitely it!
yes..it seems most unlikely that ardy is a direct ancestor...the probability that we would discover any direct ancestral line is quite low indeed considering how few and sparse fossils are...so we can call Ardy a great great cousin!
@jolsteiner Yes, I know. I grew up in a fundamentalist home / church / school. I had to teach myself how evolution works. This video is part of my education.
@McTaggStar cont..... single nucleotide polymorphisms[19] (changes of single DNA “letters” in the genome). Another type of difference, called indels (insertions/deletions) account for another ~3 % difference between the alignable sequences.[19] In addition, variation in copy number of large segments (> 20 kb) of similar DNA sequence provides a further 2.7% difference between the two species.[20] Hence the total similarity of the genomes could be as low as about 70%.
Imagine us getting dug up in a million years and studied.
Thanks to Willow Smith, I'm curious of this
@OriginalYTName OH YEAH! it's freaking awesome! I LOOVE IT! it's my life =D
@McTaggStar No one is arguing that all life is not made up of the same type of chemicals we all have DNA, but that doesn't mean that protozoa evolved into man. If we are going to consider common ancestry, then the alternative should be common design. The problem is that everyone repeats the same talking points but no one can provide any concrete examples. I asked the same of Francisco Ayala and Russell Doolittle when they made these kinds of claims, and they could not back it up either.
@McTaggStar The draft sequence of the common chimpanzee genome published in the summer 2005 showed the regions that are similar enough to be aligned with one another account for 2400 million of the human genome’s 3164.7 million bases[19] - that is, 75.8% of the genome. This 75.8% of the human genome......
Onde é q eu to?
@AtheistOnTheEdge That is probably true, humans also have an incredibly high density of sweat glands, those of us in incredible shape would be able to do "Persistence hunting" running long distances to tire out prey. Apparently a few tribes still hunt this way, and our ancestors most likely did.
cool
@McTaggStar I cited papers that had abstract easy enough to understand. You can read them if you wish or ignore them.
inserted into theory of evolution by scientific peer review.. peer review is very unforgiving...there is a study to create the model on the CG and the study itself trough scientific investigation, study and again trough scientific peer review before the modeling method takes into account...I hope you know now that there are many many steps trough the process before claiming their finding to public....:)
