Adaptations – Variation and Biodiversity Ep 5

In the last article we looked at natural selection, a process which leads to evolution. We saw that if an organism has advantageous alleles, it is better adapted to its environment and is more likely to survive and reproduce. In today's article we will look at the different types of adaptions that organisms can have … Read more

In this article we will look at the process of natural selection, and a few different types of selection. Note that there can be other mechanisms behind evolution as well, such as the genetic bottleneck effect described here. … Read more
