Answer:
1. Patterns in the distribution of living and fossil species tell us how modern organisms evolved from their ancestors.
2.They help in that, many recently discovered fossils form series that trace the evolution of modern species from extinct ancestors.
3.Evolutionary theory explains the existence of homologous structures adapted to different purposes as the result of descent with modification from a common ancestor.
4.The shell of a clam and the shell of a lobster are probably analogous, because they have a common function
5.The use of molecular clocks to track evolution includes both ribosomal RNA sequences for deep relationships and mitochondrial DNA for recent divergences.
6.The Grants have documented that natural selection takes place in wild Galapagos finch populations frequently, and sometimes rapidly, and that variation within a species increases the likelihood of the species adapting to and surviving environmental change.
