How is it possible for both Darwin's idea of gradualsm and Eldredge and Gould's idea of punctuated equilibrium to be valid?Give an example of two species that envolved due to geographic isolation.?
Many good examples can be found in the Galapagos Islands
1) Darwin's finches
2) Galč°Špagos tortoise
Punctuated equilibrium states that most populations experience little change geographically overtime. Darwin's theory on gradualism ties into punctuated equilibrium because gradualism refers to the impact of cumulative changes overtime. Thus, while there may not have been drastic changes in geography, isolation or small changes overtime could eventually lead to speciation.Give an example of two species that envolved due to geographic isolation.?
1. Green iguanas were blown out to sea. evolved into Marine iguanas
2. lizards on galapogos evolved from ancesters on mainland
