Natural selection practice

​ ​ (a)   - Organisms that have similar features and can reproduce.

​ (b)   - A group of the same species that live in a certain area.

​ (c)   -  A combination of all the different populations that live and interact in the same environment

​ (d)   - All the living and non-living things that interact in one specific part of the environment.

• Species
• Population
• Community
• Ecosystem

Eyes that can see in the dark is a(an) (a)   inherited by nocturnal animals.

• analogous
• homologous

Many different groups of organisms have wings, even though they do not share a recent common ancestor. This is because they evolved in environments with similar selective pressures. Wings are an example of a(n) (a)   structure.

• vestigial
• analogous
• homologous

Why are similar fossils found all over the world?

• The animals swam to new parts of the world before going extinct

• The land masses were once connected
