The medium ground finch is one of Darwin's finches that inhabits an island in the Galapagos. It has a small beak that it uses to eat small, soft seeds. In 1977, a drought eliminated all but the hard, large seeds. The birds who had larger beaks were able to find food and survive to reproduce while the birds who had small beaks could not find food and died. Within a few generations, the beak size of the medium ground finch increased by 10%. What type of selection is this? * O Disruptive Stabilizing

EVOLUTION CONNECTION Living members of a vertebratelineage can be very different from early members of the lineage,and evolutionary reversals (character losses) are common. Giveexamples that illustrate these observations, and explain theirevolutionary causes.
Mammals belong to a group of amniotes known as synapsids. Three major lineages of mammals had emerged by the early Cretaceous period. In a tabulated form, compare these three lineages to illustrate their diversity in terms of: a. Embryonic development b. How the young are fed c. Period of gestation
Which statement/s can best explain how evolutionary perspective help us understand senescence? (a) Evolutionary theory allows scientists to compare closely related species that differ inhow they invest in reproduction and in body maintenance, to test for effects on the agingprocess. (b) Understanding evolution can generate predictions about how individuals with certain suites of life-history characteristics might fare in the aging process when compared to other individuals without those characteristics. (c) Because aging is a natural process for all species, explaining its evolution through natural selection is insufficient. (d) Evolutionary studies provides insight into the historical development of adaptations, such as the number of offspring an individual has, that may contribute to life-history trade-offs, such as aging. A. Three of the 4 statements are correct. B. (a) and (d) C. (a) only D. (b) and (c)
Insects have three thoracic (trunk) segments. While researchershave found insect fossils with pairs of wings on all threesegments, modern insects have wings or related structureson only the second and third segment. It turns out thatin modern insects, Hox gene products act to inhibit wingformation on the first segment. The treehopper insect (above)is somewhat of an exception. In addition to having wingson its second segment, the treehopper’s first segment has anornate helmet that resembles a set of thorns, which a recentstudy has found to be a modified, fused pair of “wings.” Thethorn-like structure helps to camouflage the treehopper intree branches, thus reducing its risk of predation. Explain howchanges in gene regulation could have led to the evolution ofsuch a structure.
In 1798, a stuffed platypus specimen was delivered tothe British Museum. Reports that it laid eggs createdmuch confusion. To modern biologists, a platypus isclearly a mammal. It has fur and the females producemilk. Young animals have typical mammalian teeth thatare replaced by hardened pads of the “bill” as the animalmatures. Why do you think modern biologists can moreeasily accept that a mammal can have some reptileliketraits than scientists who were considering this animal inthe late 1700s?

House sparrows (Maya) were introduced to North America in 1852. Since that time thesparrows have evolved different characteristics in different locations. Sparrow populations inthe north are larger-bodied than sparrow populations in the south. This divergence inpopulations is probably at least partly a result of natural selection: larger-bodied birds canoften survive lower temperatures than smaller-bodied birds can. Colder weather in the northmay select for larger-bodied birds. What type of evolution based on natural selectionaccounts for this observation? Explain your answer.
A similar trait that is found in two different species (ex. streamlined bodies, wings, etc). Whether this trait is homologous or analogous in these two species, and why or how.
. The upper forelimbs of humans and bats have fairly similarskeletal structures, whereas the corresponding bones inwhales have very different shapes and proportions. However,genetic data suggest that all three kinds of organisms divergedfrom a common ancestor at about the same time. Which ofthe following is the most likely explanation for these data?(A) Forelimb evolution was adaptive in people and bats, butnot in whales.(B) Natural selection in an aquatic environment resulted insignificant changes to whale forelimb anatomy.(C) Genes mutate faster in whales than in humans or bats.(D) Whales are not properly classified as mammals.
Knowledge of the genomes of ancient homininsmight help us better understand not only the evolutionaryhistory of hominins, but also the traits that differ between usand our relatives—the traits that make us human. Our understandingof the functions of different genes is growing rapidly,so detailed comparisons of our genes to those present in, say,Neanderthals and Denisovans are very revealing. What do youthink are the functions most likely to be related to the geneticdifferences between us and our hominin relatives?
