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.
Microtaxonomy ( Species and Speciation ) People who do not believe in evolution often cite the classic example of man presumably evolving from the apes. They oftern ask: if humans evolved from apes, why are there apes until today? How will you provide a convincing answer that there is no contradiction in the existence of apes and humans at the same time?
Through _______, a body part of an ancestor is modified differently in different lines of descent. a. homologous evolution b. morphological convergence c. adaptive divergence d. morphological divergence
Approximately how many mass extinction events occurred throughout the evolutionary history of animals? 3 4 5 more than 5
In 1798, a stuffed platypus specimen was delivered to the British Museum. Reports that it laid eggs created much confusion. To modem biologists, a platypus is clearly a mammal. It has fur and the females produce milk. Young animals have typical mammalian teeth that are replaced by hardened pads of the bill as the animal matures. Why do you think modem biologists can more easily accept that a mammal can have some reptilelike traits than scientists who were considering this animal in the late 1700s?
Two species of fish had recently undergone sympatric speciation. The males of each species had a different coloring through which females could identify and choose a partner from her own species. After some time, pollution made the lake so cloudy it was hard for females to distinguish colors. What might take place in this situation?
The oldest Homo sapiens fossils were found in __________ a. the Middle Hast b. Africa c. Indonesia d. Europe
Which of the following is part of a clade believed to have died out, leaving no descendants? Paranthropus robustus Australopithecus africanus Homo erectus Homo sapiens sapiens
Adaptive radiations often follow mass extinctions because: a. mass extinctions limit the impact of paedomorphosis. b. mass extinctions foster allometry and heterochrony. c. mass extinctions decimate all forms of life on Earth. d. species that form transitional fossils often survive mass extinctions. e. extinctions open adaptive zones that had been previously occupied.
In a cladogram, each node represents a(n) _______ . a. single lineage b. extinction c. common ancestor d. adaptive radiation
Mountain gorillas are a highly endangered primate species, with 800 or so individuals surviving in the two remaining populations. A recent sampling of mountain gorilla genomes revealed a very low level of genetic diversity. Explain why a decline in genetic diversity often accompanies a decline in population size.
Hello, I need help answering number 1 (INCLUDING SUB-PARTS) true or false questions. Pls and thank you! 1. A.) T / F - All evolutionary responses to natural selection involve a genetic change. B.) T / F - If character polarity is not correctly determined, it is impossible to make a cladogram that matches the true evolutionary history of the group studied. C.) T / F - Endangered species whose effective population size (Ne) remains small for many generations will mainly evolve by adaptive evolution.
