Too bad nobody has picked up on this topic. These early finds are important.
Problem is, it takes quite a few years to fit them into the existing database. As each new discovery is made, each previous discovery is re-evaluated (science in action). Sometimes it takes a while for a consensus to be reached as to what exactly the new discovery is/means. By the time scientists figure out just where a new specimen fits, the media have lost all interest and most folks don't get the details of how the initial claims have been narrowed down. KNM-ER-1470 is a good example. The dates and assignments have both changed (more than once) since the initial announcement back when I was studying fossil man in graduate school. So, I'll wait around to see what others think about this new find.

Well, if no one else is going to say it:
Two more holes just popped up in evilution. That means you gotta go find two more of those non-existent missing-links. Checkmate, scientists!

It's always nice to see the holistic approach ...

Declaring The Discovery Of A New Species Can Get Tricky
quote: It seems to me that if you have two contemporaneous populations with morphologically distinct features that that would be evidence of genetic isolation.

There's probably more ego than science at play in all of this.
Who wouldn't want their name attached to the discovery of a new species instead of a new variety?Love your enemies!

It seems to me that if you have two contemporaneous populations with morphologically distinct features that that would be evidence of genetic isolation. But when one of your populations consists of three partial jaws, the question is whether it is in a fact a distinct population, and we haven't just improved our sample of the variation in one existing population. There are plenty of low frequency traits in modern humans. When the squid people discover one of these for the first time millions of years in the future, clustered together as heritable traits tend to be, it would be rash for them to declare a new species of modern human.

Exactly right. We don't yet know what the range of variation might be. And to make it worse, those transitionals are sneaky! They look a bit like one group and a bit like the other.Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.

And I would agree, were it not that there are quite a number of fossils of the other australopithecines iirc, and that these purportedly fall outside those fossils. However I see this as part of the peer review process -- an hypothetical suggestion is made and it is reviewed by others in the field, the hypothesis is tested against the known information and predictions of future finds are made to either confirm or refute it. Maybe I like to think of evolution as bushy rather than linear, or maybe like an ivy with a lot of tendrils that branch off.

Large for a hominin species, but not really that large in an absolute sense. I tried to find some more specific numbers, but that proved a lot harder to do than I expected. Anyway, as we (or, at least, I) don't have a subscription to Nature, so don't actually know how different these fossils are from Australopithecus afarensis, I guess we can leave it to the experts to argue over for now, as you suggest!

There is the old country status referred to as "Kissin cousin twice (or thrice) removed" that may well be applicable in this case. It's for them folk that alust show up when thar's meat on the grill and lonst as there eatins and space at the table you make them feel welcome cus you knows youse related but ain't quite sur how.
