I chose to post this article as a supplement to what was said in today's #MB1005 Genes lecture. For more than a decade, scientists have been studying the "exclusion zone" which had been set up around the site of the impact. It has been found that level of insects and birds diversities have fallen. Moreover, it has been found that the birds's brains are relatively smaller compared to other birds from other sites. That suggests that many bird embryos did not survive at all, due the negative effects of their developing brain. - Mehrine Elahee
