Process of Evolution Questions and Answers Rated A+ An example that shows adaptations for plants growing in the desert? spines to protect plants against animals seeking water An example that shows adaptations for plants growing in the desert? a waxy coating on leaves to reduce water loss The foramen magnum position is the hole in the skull where the spinal nerve cord passes through. Which statements can you infer? organisms share a common evolutionary lineage & Humans likely share more common ancestors with chimpanzees than they do with wolves. In the Galapagos Island finches, the variation in the beak shape corresponded to which finch characteristic? their diet Red and green beetles from a forest migrate to grasslands. In the new environment, green beetles are able to protect themselves better from predators through camouflage. Which change in the population will most likely happen over time? Most of the beetles will be green. Rock pocket mice with different color variations are observed in the desert regions of Arizona. The fur color of the mice helps them blend in with their environment to avoid predators. There are black basaltic rocks in the southwest region of the desert. However, most of the desert regions have sand that is light brown in color. Which two statements are true about the population of mice in both regions? Black mice will be better adapted in the black basaltic rock regions. & Light brown mice will be better adapted in the sandy regions of the desert. On island X, he saw both species of finches. On island Y, he only saw the finch on the right. Based on these observations, what is the most likely conclusion Darwin would have made? There was a variety of food available on island X, but there were only large seeds and nuts on island Y. provide evidence from developmental biology of a shared evolutionary history? Both lobsters and frogs go through metamorphosis as a process in their life cycle. How did the artificial selection practiced by pigeon breeders influence Darwin's theory of evolution by natural selection? Darwin concluded that if traits in captive pigeons could be selectively passed on to offspring, the selection of traits could also happen I nature, On the Galapagos Islands, Darwin observed tortoises with domed and saddle-shaped shells. How did Darwin's observations of these tortoises help him form the theory of evolution by natural selection? The tortoises provided evidence that different species have adaptations suited to their particular environments. Approximately 60% of human genes are also found in fruit flies. About 97.5% of human genes are also found in mice. What does this evidence suggest? Humans and mice share a more recent common ancestor than do humans and fruit flies. What did the evidence that Darwin collected during his voyage on the HMS Beagle allow him to accomplish? to propose the theory of evolution by natural selection Researchers have historically considered the human appendix to be a vestigial structure. What evidence, if true, would best disprove this claim? The human appendix helps to maintain the health of the gut, and arose fairly late in the evolutionary history of mammals. The images show the wings of two different organisms. The wings of the housefly and the bat are analogous structures. This indicates that their wings have different evolutionary lineages. Which field of study matches with "embryo of a pig and a calf" ? developmental biology Which field of study matches with "DNA of a pig and a calf" molecular biology Which field of study matches with " limb structure of a pig and a calf" comparative anatomy Based on this phylogenetic tree, which species is most closely related to Bos taurus? Ovis aries Giraffes with short necks lived in arid regions and fed on grasses. Over time, grasses disappeared, forcing giraffes to eat from trees. Mutations in the genome led to some giraffes inheriting the trait for long necks. Over time, there were more giraffes with long necks in the region. What are the two reasons for the change in the population of giraffes? adaptation & natural selection Match the characteristic with the correct evidence for evolution: The inner ear bones of mammals have evolved frombones that form the jaws of reptiles. homologous strucutures
