Base your answers to questions 84 and 85 on the information below and on your knowledge of biology. The diagram below represents a recently developed evolutionary tree for some species of birds. The new tree diagram is based on the analysis of data collected from 169 bird species and includes a change in the placement of fl amingos. The fl amingos are now grouped with the grebes and pigeons instead of with egrets and penguins. Group B Group A Crows Eagles Egrets Finches Hummingbirds Owls Penguins Woodpeckers Flamingos Grebes Pigeons Source: Science News 1/10/1584 Identify one type of molecular evidence that was most likely used to develop this new tree. Explain how this evidence would support the new position of the fl amingos. [1]85 Based on the photos above, select two bird species, one from Group A and one from Group B, and state one reason why researchers may have originally thought these two species should be on the same branch of the tree. [1] Bird species from Group A: Bird species from Group B:
