Early Ideas of Evolution

What idea did Thomas Malthus contribute to Darwin's hypothesis?

• Species evolve by using or losing their traits

• Human population will increase faster than food and other resources

• Natural selection is the driving force to evolution

• That Earth changes at a constant rate by natural processes

What do Fossils show us?

• Exactly what dead organisms looked like

• How much or how organisms have changed over time

• How organisms have stayed the same

Darwin referred to this as survival of the fittest. Over time, it results in changes in the inherited characteristics of a population because organisms with adaptations that make them fit for their environment will survive and reproduce better than those without favorable traits.

• Natural Selection

• Genetic Variation

• Survival of the Fittest

Which of the following is NOT one of the main points of Darwin's ideas about natural selection?

• Most species produce far more offspring than survive

• Food and resources in any given habitat are limited, so species must compete to survive

• Traits are determined by an organism's immediate needs

• Members of the same species often have different traits because they have variation

What is suggested by the similarity of early embryos of different species of vertebrates?

• no evolutionary relationships between the groups

• recent common ancestry

• similar environments in the past

• evolution from a distant common ancestor
