On the islands of Hawaii there are a group of about 30 species of highly variable, but closely related, species of plants called silverswords. These species appear to be related to a small group of plants in North America. What are the silverswords
very large, have random mating, no geneflow, no mutations, no natural selection
random mating
adaptive radiation
They show that ancient species share similarities with species now on Earth
result in increased genetic variation
fossils
traits as adaptations
Hardy-Weinberg principle

Some features in organisms can be compared to spandrels in architecture in that, although they appear to have a function, they are really just there because of the evolution of other structures. This analogy is used as an argument for care in identi
