RE: What Did You Learn Today?
After my finals are over, I have to write a brief paper on whether or not Paranthropus robustus, sometimes known as a member of the "robust" australopithecines, was a tool user/maker. I'll post this in the science thread when I get done.

Which way are you leaning? And how complex/advanced does the tool have to be? Can a be stick into a termite nest or does it have to be a flint cutting tool? I take it no tools have been found among their bones.

Can't wait to see what you come up with.

I believe they were tool users. There are several reasons for this:

* Their fossils have been found in the same area with simple bone tools.
* These bone tools have marks similar to tools used for foraging for termites and digging for tubers.
* Their teeth have marks on them that most likely came from chewing hard tubers.
* Chemical analysis of their teeth shows they were food generalists (food specialists don’t use tools).
* Their thumbs have very robust apical tufts, a must for the manipulation of tools.
* The Oldowan stone complex predates P. robustus by half a million years.
* Recent research has suggested the Oldowan stone tools were made by individuals more on the ape line.
* They had the same brain capacity as a chimp.
* Most importantly, experiments have shown that captive apes are capable of manufacturing tools.

RE: What Did You Learn Today?
The evolutionary change in the brain pan is quite interesting. For starters, here are a chimp and an Australopithecus afarensis skull. Both are shaped like bells. The widest point is at the bottom.

The erectus skull fills out more in the parietal area. It's almost as if the shoulders of the bell were pushed outwards. My professor says it has a "tent" shape.

The neanderthal skull was widest in the middle. It is often described as having a barrel shape.

The widest part of the human skull is near the top. My professor says its shaped like a pentagram.

Even if no one knew the dates associated with each skull, I think they would be able to deduce which came first and in what order they should be placed.

How clean is that washcloth?

Machine washed, put and taken out of the towel drawer and then sitting on my desk for a few days 'clean.' I used milk shortly after that, and did the same thing with no acid smell this time. I now blame the creamer, which I will use later on.

Or perhaps to strip paint?

... Er... so this thing hangs a nice-looking packet of sandwiches or something close to the riverbank and waits ?
