Evolution Flashcards
what is evolution?
evolution is the change in characteristics of a species of several generations and relies on the process of natural selection.
what is divergent evolution?
the process in which organisms with a common ancestor evolve and accumulate differences, which results in the formation of a new species.
what is convergent evolution?
the process by which different organisms not from the same common ancestor, develop characteristics in similar appearance and structure.
what is an example of convergent evolution?
sharks and dolphins have the same streamlined shape despite being unrelated due to aquatic evolution.
what is an example of divergent evolution?
Darwin’s theory about finches in example of divergent evolution, he discovered that there were several different species of finch despite the fact they shared a common ancestor. They had different sized and shaped beaks which reflected their individual and unique diets.
