Understanding Evolution

Who proposed the theory of evolution by natural selection?

• Albert Einstein

• Galileo Galilei

• Isaac Newton

• Charles Darwin

What is the significance of genetic variation in evolution?

• Genetic variation is crucial for evolution as it enables adaptation and survival through natural selection.

• Genetic variation is only important for individual health.

• Genetic variation has no impact on species survival.

• Genetic variation leads to uniformity in populations.

How do fossils provide evidence for evolution?

• Fossils show the historical progression of species and provide evidence of common ancestry and transitional forms.

• Fossils are created by volcanic activity and have no relation to living organisms.

• Fossils are only found in sedimentary rocks and do not indicate evolution.

• Fossils can only show the age of rocks, not the history of species.

What is natural selection?

• Natural selection is the belief that species do not change over time.

• Natural selection is the method by which all organisms are equally likely to survive.

• Natural selection is the process of random genetic mutations.

• Natural selection is the process by which organisms that are better adapted to their environment tend to survive and reproduce more successfully.

What is the difference between homologous and analogous structures?

• Homologous structures share a common ancestry; analogous structures serve similar functions but do not.

• Analogous structures arise from the same evolutionary path as homologous structures.

• Homologous structures are always larger than analogous structures.

• Homologous structures serve similar functions while analogous structures do not.
