While looking for something
that will keep my interest along side with this weeks Thanksgiving festivities,
I came across an interesting article called “Big Brains are All in the Genes”. This article focuses on how through evolution
our brains became larger and more complex. The scientist wanted to understand
the genetic changes that are related to various adaptations in acquiring a
lager brain. Gene families in thirty-nine different species of mammals were
analyzed. These gene families are group of genes that are related to each other
in some function. From the research done, there was a link between the various
size of brain and the amount of gene families associated together. Thus the
greater the amount of gene families linked together, the more complex and
bigger the brain will be according to this research.
