The mechanism of microevolution that caused the beak of the medium finch population to increase size was natural selection.

About in 1977-78, during and after the drought, the Finches population has increased by 93-189 Finches in between January and March.

The increase of beak length and depth in 1978, from about 9-10mm in depth and 8-14mm in length.

Portulaca seeds have decreased more drastically than the Tribulus by 2-6 seeds less than the Tribulus seeds.

Portulaca seeds have decreased more drastically than the Tribulus by 2-6 seeds less than the Tribulus seeds.

Portulaca seeds have decreased more drastically than the Tribulus by 2-6 seeds less than the Tribulus seeds.

This is important to know as the seeds were the first cause of why many  Finches with thinner/smaller beaks died out first.]]> 2021-02-05 13:51:12 UTC https://padlet.com/haileythornhill25/dmeru696m4urjhiq/wish/1168199937
