The article you have a link to did a good job showing how as more evidence occurs we can refine our interpretation. That's what makes science such a powerful tool of discovery. The fact that we have not yet found the last common ancestor does not weaken the theory of evolution and the accumulating evidence as presented demonstrates that all of the new evidence supports evolution and no other explanation. Thank you for the link.
You're welcome. Glad you like it. (Isn't the chimp cute, though?) Especially as a close link and relative.
When I think about it and look at his cute face, it makes me smile, if not laugh.
So rather than explaining definite circumstances such as what is the humans closest related link, scientists say, in essence, they don't really know. Especially because their concept keeps changing, based upon discovery and opinion putting it all together within the 'theory.' And now there's more changing opinions about evidence. You can say it's great they keep coming up with new ideas about what's what within the realm of evolution, but when looked at precisely, they
don't really know.
"There appears to be a decrease in overall body size within our lineage, rather than size simply staying the same or getting bigger with time,
which goes against how we generally think about evolution," Grabowski said. Oops. Goes against how they generally think about evolution.
And it is not just possible, but likely, that the
opinion (how they generally think about evolution) will change again. Because --
they admit they don't really know. Now when a person admits they don't really know -- because something enters the picture to go against the general thinking about evolution, whether you accept that as reality of evolution, or that scientists don't really know, is up to one's perception of reality.
New study suggests that last common ancestor of humans and apes was smaller than thought
