What I have drawn here spans a period of something like 10 million years. Remains of possible ancestral forms are about maximal 6 million years.
The early populations of ourselves, Homo sapiens, where already bigger in an early stage and with reaching the 9 billion or more.....
My description of us is something like this:

Walking, swimming, singing, overkilling, diving, fucking, dangerous, ........

Rather negative, but look at the " history" you is learned . We find it in very old paleolithic and archeologic sites  (cont).
