Okay, anyone who is interested -

Are the following capsules of information factually correct?
Think of it as a test of things you learned long ago!

Australpithicus afarensis
=========================
. 5 mya - 3 mya
. the earliest Australophiticus
. walked erect
. 310-485 cc brain, "ape-like" organization
. 3.5 to 5 feet tall, very stocky
. lived in trees and on the ground
. no tools yet
* NOTE: bipedalism came long before human-like brain!

Australpithicus africanus
=========================
. 2.8 mya - 1.8 mya
. 428-510 cc brain, roughly the size of a chimp's
. brain expanding but still "ape-like"
. built like A afarensis
. maturation period still as short as apes (3 years)
. represents either an evolution towards homo, or
an evolutionary dead-end
