What is a homologous structure?
structures are physical features found in different organisms that share a common ancestor

After traveling to the Galapagos Islands, Darwin noticed a lot of variation among beak sizes in Finches. This variation was a result of:
Developing different adaptations in order to survive on particular islands (having beaks adapted to food sources)

What is a vestigial structure?
A vestigial structure is a physical structure that has reduced in function from an ancestral state and is no longer functioning.
500
What are the 3 factors that affect natural selection?
What is variation (in a species), competition for resources and fitness

Iguanas on the mainland have smaller, sharper claws compared to the larger, meaty claws found on island iguanas. Why did the two populations of iguanas develop claws with different physical traits?
What is the mainland iguanas and the island iguanas adapted claws that better suited their environment which allowed them to survive and reproduce

A population of hummingbirds have long beaks and short beaks. The flowers the hummingbirds usually eat from have died and now the hummingbirds need to eat from smaller flowers. How will the population of hummingbirds change?
The hummingbirds with long beaks will die and there will be more hummingbirds with short beaks.
