What was the mean day time air temperature was supposed to have
been around the time when the savannah-boys and girls were
bipedaling away? Does anyone know?

What was the daytime water temperature around that time, around
the sea shore somewhere around the equator in Africa?

If the air was dry the nights should have been colder depending
on the dryness. So what is the estimated day-night temperature
differential around this time?

Any answers?
