homologous structures

natural selection acts on ____ traits

inherited

His theory of evolution was based on acquired traits

lamarck

Darwin was inspired by his ideas on population growth

related

Natural selection depends on the ability of organisms to ____, which means to leave descendants.

reproduce

Distantly related organisms may be similar if they live in _____

similar environments

When individuals from a mainland bird population immigrate to various islands, natural selection may result in _____, but different, island species

similar/closely related

Lyell thought most geological processes operated extremely _____
