Darwin studied actual birds on the Galapagos Islands instead of using a simulation, as you did in this lab. Studying natural selection in the field can be challenging. List at least three possible challenges Darwin might have faced

Traits other than beak type might affect natural selection.

It could take many generations to observe adaptions to a population.

The environment may be complex and hard to study.

Changes in the environment may occur faster or slower than changes to the birds

The birds may be interdependent with other organisms that may change, too.

Explanation:

which

what is a measurement of the earth’s history divided into time periods?

> fossil record <

sedimentary rock

> geologic time scale <

radioactive elements

on island x the species needed to adapt because they were being subject to predators which didn't inhabit island y.
