1) Darwin's studies of Galapagos finches are well known in the study of evolution. These studies have been instrumental in helping us understand how new species evolved from pre-existing species. Which statement is true about the speciation of the Galapagos finches?
A) The finches evolved traits to help them survive in different environments.
B) The finches had different traits that influenced the environment in which they chose to live.
C) Genetic variation occurred amongst the finches, giving some a genetic advantage in a changing environment, allowing them to better survive.
D) Members of the original population evolved in such a way that it became impossible for individuals from the two new populations to interbreed.

- How do mechanisms of speciation, such as genetic isolation, reproductive barriers, and ecological factors, apply to the human-chimp-gorilla trichotomy? Discuss the role of these mechanisms in driving speciation and shaping the evolutionary relationships among humans, chimps, and gorillas, based on genetic evidence such as comparative genomics and molecular phylogenetics.arrow_forwardBelow is a phylogenetic tree of flightless birds. Which species is the common ancestor, with shared characteristics to the flightless birds shown below? A) Great spotted kiwi B) Chicken C) Ostrich D) Greater rheaarrow_forwardHow, specifically, is the concept of ALLOMETRY relevant to the phylogenetic position of Homo floresiensis? Because if allometry explains the anatomy of Homo floresiensis then we can conclude that it is not separate species but instead a member of our species. Although most mammals on islands go through a process of getting smaller, Homo floresiensis evolved from a smaller ancestor to be bigger, meaning that allometry is an important factor. Mutations in the allometry allele are associated with many of the characteristics of Homo floresiensis. Because Homo floresiensis is so much smaller than other members of the genus Homo, it is important to determine how shape changes associated with smaller size impacted the species. Because Homo floresiensis had both small- and large-bodied forms, variation within the species is in large part dictated by allometry.arrow_forward

- A phylogeny of 5 species of birds is shown below with values for three different phenotypic traits for each species shown in the rows above (e.g., species A has a wide, long beak and red tail, while species C has a narrow, very long beak and a green tail). DNA sequencing of tissue samples found buried in a freezer confirms that an extremely rare and reclusive species (D) is a sister species of E, but preserved samples of entire individuals of species D have been lost, the original collector of the samples has passed away, and no individuals of species D have subsequently been seen in the wild. In other words, we have no idea what species D looks like. Employing the principle of parsimony, which of the following conclusions is MOST appropriate for the likely values of these traits in species D? Beak width: wide wide ?? narrow narrow Beak length: long long ?? long very long Tail colour: red blue ?? green green A E a) wide beak, very long beak, green tail b) narrow beak, long beak, all…arrow_forwardWhat type of geographic barriers could have led to the speciation of finch in the Galápagos Islands?arrow_forwarda) Is Figure 1 a cladogram, phylogram, or chronogram? b) According to Figure 1, all bears share a common ancestor with what group of mammals? c) What pair of bear species diverged most recently? d) The ancestor of what species of bear diverged the earliest from the ancestor of all other bears?arrow_forward

You are a primatologist, and you are trying to determine its phylogenetic position. You are sure its closest relatives are Species B and Species C, but you want to know which one it is more closely related to or if it is equally closely related to both. You are using Species D, a more distant relative, as the outgroup. You have come up with a list of ten characters you think will be useful in resolving this phylogeny, and you have determined the character state of each species for each character. The character states are: (in image below) Estimate the phylogeny of these taxa by plotting the changes on each of the three possible phylogenies for species A, B, and C and determining which tree requires the fewest evolutionary changes.

Fossil evidence showing that the common ancestor of species A, B, and C had long wings E. Evidence showing that species A and B live in an environment that favors long wings, whereas species C lives in an environment that favors short wingsarrow_forward
