Title: Which of these human characteristics evolved first? Post by: mikael on Apr 25, 2014 Which of these human characteristics evolved first?
A) enlarged brain B) erect posture C) language D) loss of body hair Title: Re: Which of these human characteristics evolved first? Post by: ehd123 on Jun 4, 2014 B) erect posture
* Actually, erect posture was taking place while the brain size was enlarging (to be able to withstand a task [going from quadriped to biped] was thought to be of a large magnitude for a small brain to be able to handle).. But erect posture was what triggered the increase in the brain size.. Makes sense? Title: Re: Which of these human characteristics evolved first? Post by: mikael on Jun 4, 2014 Thank you.
