Biogeographical patterns provide clues about how species are related to each other • The fossil record, though incomplete, provides information about what
Two biogeographical patterns are significant to Darwin's theory The Closely Related but Different To Darwin, the biogeography of
Closely related organisms go through similar stages in their embryonic development because they evolved from a common ancestor • All vertebrates go through a
Organisms that are closely related may also have physical similarities before they are even born Take a look at the six different embryos below:
Biogeography – the geographical distribution of living species They were also slightly different from the most similar species on the mainland of South
Biogeography has had a long history, but only recently has it started to be closely related species living in very differ- ent, but adjacent habitats
Whales and dolphins can breed with one another to produce a new species 11 Apply concepts A scientists studies two organisms with many similar traits He
