Samantha Johnson describes how she uses the short film "The Origin of Species: The Beak of the Finch" to demonstrate to her students how quickly selective pressure can affect a population, as well as to show that not all science is done indoors. If the climate is not very wet for a long time then small seeds become unavailable. the intermediate would learn its song from whichever neighboring species it had. Explain. Created by. They also identified behavioral characteristics that prevent different species from breeding with one another.
