ANT203H5 Lecture Notes - Lecture 12: Phenylalanine, Hydrolase, Plasmodium Malariae
Document Summary
Humans occupy a wide geographic range, living under all kinds of environmental conditions. It is important to mention that the environment not only comprise external factors, such as temperature or humidity, but internal factors as well, such as infectious diseases. I. e. , malaria many regions of the genones have been selected based on the genome of malaria. In this lecture we will review ways in which humans respond to environmental challenges. There are four main ways in which humans respond to environmental stresses: cultural practices and technology, acclimatization, developmental adjustment, genetic adaptation. We will review very briefly each category and study in more detail different examples of genetic adaptation. There are uncountable examples on how culture and technology have allowed humans to adapt to multiple environments. Since the origin of anatomically modern humans, this has become our main adaptive strategy. Of course, humans have been perhaps too successful with this approach.
