Summary of the Ascent of Mind... Chapter 1

I read this chapter of the this online book after we studied evolution in my boilogy class. It also has a connection to my research paper bcuase of its connection to the brain and how it works. The authour of this book is W.H. Calvin, and it tracks the evolution of the human species and their brains through time. This chapter examins how we came to the state that we are in as a species from the the first human like species till now. Calvin tracks the movement of humans arcoss the moving contenents and their evolution. We see the evolutionary growth in brain size from homoerectus (smallest brain), to homosapiens, to neadertals and then our most current staet of being (lagest brain). we see that these evolutionary changes are a result of the changing climate and different demands excerted by the land. All of this time our brain is growing in size and aquireing more folds that allow us a greater brain capasity and more complex thoughts and ideas. (20 pages)
