Finches Beaks

During drought seasons, Finches with larger beaks survived better and longer than Finches with smaller beaks. During rainy times Finches with smaller beaks got seeds that grew easier because they had easier access.

Natural Selection Definition

Natural Selection - Natural Selection is the ability to produce fertile offspring along with being fit.


Being Fit in a species means that you can pass down trait and survive longer and better within the environment that they are in.

Determination and Selection

Natural Selection is determined by the environment!

This species may be selected out because of their beak sizes and differences, which may help them survive according to their environment and weather around them.
