Factors such as environment and predation pressures can have different effects on the ways in which species exposed to them evolve.

Example, amphibians that lived in water and land, had to adapt over the millions of years to live on land. Instead of fins or webbed feet, they grew such bone structures that were similar to feet.  ]]> 2017-06-14 07:29:28 UTC https://padlet.com/joshua_burkhart/30x82bd81lop/wish/176360835 joshua_burkhart https://padlet.com/joshua_burkhart/30x82bd81lop/wish/176361600 Much like the homologous structures, the organs adapted too.

As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation. Depending on how a particular mutation modifies an organism's genetic makeup, it can prove harmless, helpful, or even hurtful. Sometimes, a mutation may even cause dramatic changes in the physiology of an affected organism.]]> 2017-06-14 07:51:32 UTC https://padlet.com/joshua_burkhart/30x82bd81lop/wish/176363073 joshua_burkhart https://padlet.com/joshua_burkhart/30x82bd81lop/wish/176363488 2017-06-14 07:56:12 UTC https://padlet.com/joshua_burkhart/30x82bd81lop/wish/176363488
