A population of squirrels is preyed on by small hawks. the smaller squirrels can escape into burrows. the larger squirrels can fight off the hawks. after several generations, the squirrels in the area tend to be very small or very large. what process is responsible for this outcome?

Respuesta :

They are either large because the biggest were able to fight the hawks and small ones were able to dig into small burrows better. The medium sized ones couldn't do either so they died and did not pass on there genes.
