What is an organism's ability to survive and reproduce in a particular environment called?

A bird is born with a long beak and this helps it capture food and therefore survive better. What is this an example of?

What type of evolutionary evidence shows links of the past and tells the story of how organism have changed over time?

What type of evolutionary evidence shows different organisms share similar structures that have very different functions, or have remnants of structures /organs that had a function in the past?

What type of evolutionary evidence shows that during the early stages of life different organisms appear to be very similar, and become increasingly different as they grow.

What type of evolutionary evidence show common ancestry reflected in the universality of DNA as the genetic material?

What type of evolutionary evidence shows that different habitats favor different traits and can establish separate populations that have a common ancestor?

The body parts in the image have similar structures but different functions. This is an example of what type of structures?

The hip bones are no longer used in modern day whales but where used in their ancestors. This is an example of what type of structure?

What is shown by many of the forms of evolutionary evidence? (An ancestor that two or more descendants have in common)

Human skulls have increased in capacity and jaws have _______________ in size.

What type of evolution happens when unrelated species often evolve similar traits that help them survive in their environment?

What type of evolution happens when groups from the same common ancestor evolve and accumulate differences, resulting in the formation of a new species?

What is any change to a DNA sequence? It can be good, bad or neutral?
