According to the principle that the environment "sculpts the form," what is the primary role of the environment in the process of evolution?

To create entirely new body plans from scratch for each new habitat.

To select for modifications in existing structures that improve an organism's function.

To ensure that all species maintain their original ancestral form without any changes.

To randomly change the skeletal structure of organisms regardless of their survival needs.

A scientist comparing a bird's wing and a bat's wing notes that the underlying bone structure is very similar, even though their overall shapes are different. What does this similarity in bone structure primarily indicate?

That both species adapted to flight in the exact same way.

That birds and bats are adapting to live in the same specific habitat.

A shared ancestry and a common inherited body plan.

That the shape of a wing is more important than its bone structure.

The new functions required for survival.

The inherited ancestral body plan.

The specific habitat an organism lives in.

Random mutations that occur during an organism's life.

Their diet and feeding behaviors.

The specific color patterns of their skin or fur.

The fundamental structure of their skeletons.

The continent where they currently live.

A close evolutionary relationship between sharks and dolphins.

That both species inherited this exact shape from a recent common ancestor.

That sharks will eventually evolve into mammals if they keep the same shape.

Adaptation to similar environmental pressures of moving efficiently through water.
