'The first humans may have started walking upright because the place where they lived was so hot, new research suggests.Scientists discovered that the Turkana Basin of Kenya, long held as the cradle of human evolution, was even hotter millions of years ago than it is now.
Daytime temperatures would have been well into the late 90s every single day.
The discovery lends weight to the so-called ‘thermal hypothesis’ of human evolution, which states that mankind first started standing upright because of the intense heat.'
Phew! Our evolution-creating pals are having a bit of a field day here!
Well. That's really won me over. The explanation is just so - er - well - sensible. Perhaps 'logical' is the word I really needed.
It certainly explains why homo erectus is - so - er - upright.
In fact it also explains perfectly why there are so many lions, jackals, cheetahs, zebra and antelope walking upright today!
(In fact if you check the photo you will see that I have even included a picture of an 'upright zebra' to help in understanding.)
