Textbook Question
Chapter 23, Problem 5S
Birds, pterosaurs (a type of flying reptile that lived in the Cretaceous period), and bats all have modified their forelimbs to serve as wings, but they have done so in different ways. Are these structures homologous? If so, how can they be both homologous and convergent? Do any organisms possess wings that are convergent, but not homologous?

- If mutations such as those of the Ubx gene can drastically change morphology in a single step, why do most evolutionary biologists maintain that modification of existingtraits and the evolution of novel characters have generally proceeded by successive small steps?arrow_forwardIt is possible for two different genes to imply different phylogenetic relationships among a group of species. What are the possible reasons for this? If there is only one true history of formation of these species, what might we do in order to determine which (if either) gene accurately portrays that history? Is it possible for both phylogenetic trees to be accurate even if there has been only one history of species divergence?arrow_forwardWhat is convergent evolution? Give an example.arrow_forward
- Why can't we just use DNA for all of the fossils to determine, more accurately, relatedness between extinct and extant species?arrow_forwardMatch the following statements to the correct term. Statements- -characters that are found within two descendants but not necessarily within their common ancestor -two structures that look alike and arise through divergent evolution -a term that can describe two structures that share common features but do not derive from a common ancestor -a term meaning more than one common ancestor Terms- -Analogous -Shared ancestral characters -polyphyletic -homologous -monophyletic -shared derived charactersarrow_forwardStructures in two different species may be similar because of either of two very different reasons. Describe these two reasons. You must use all four of the following terms in your explanation: homologous structures, analogous structures, convergent evolution, and divergent evolutionarrow_forward
- Draw a phylogenetic reconstruction for the hypothetical frog species. Once you have a cladogram you feel confident about, use lines and labels on cladogram to indicate where character states hanged. How many evolutionary changes occurred in your phylogeny? Is there evidence of an evolutionary convergence having occurred in your phylogeny? How about evolutionary reversals?arrow_forwardCan convergent (or parallel) evolution of similar morphology in two different lineages involve DNA sequence evolution in different parts of the same developmental gene? Explain how.arrow_forwardDoes this phylogenetic tree represent the same evolutionary relationship between all the taxa? why or why not?arrow_forward
- When I first studied hominin evolution, they had found "Lucy", an Australopithecus afarensis, and everyone thought her species was an early ancestor of Homo sapien. The picture is much more complicated, with lots of hominins living in close proximity for millions of years...much different than our now singular species. Look at the phylogenetic tree and use it as a guide to briefly describe hominin lines in Africa up to Homo. Do not discuss Homo.Just discuss a sense that you generally can grasp what was going on in Africa with our Genus for 6 or 7 million years!arrow_forwardThe figure shows a phylogenetic tree of various members of the order Proboscidea, which includes modern elephants. Which of the following claims is best supported by the information in the figure ? a.The mastodon and the Stegodon diverged from their common ancestor 22 million years ago. b.The common ancestor of the African elephant and the mastodon is the Palaeomastodon. c.The mammoth diverged from its most recent common ancestor with African elephants before the mastodon diverged from its most recent common ancestor with Stegodons. d.The Asian and African elephants are the most closely related species shown on the tree.arrow_forwardHow is convergent evolution different from evolution by common descent?arrow_forward
