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
In what way does the modern synthesis strengthen scientific understanding of evolution? (a) is based on the sequence of fossils in rock layers (b) uses genetics to explain the source of hereditary variation that is essentialto natural selection (c) was first proposed by ancient Greek scholars (d) considers the influence of the geographic distribution of organisms on their evolution (e) is reinforced by homologies that are explained by common descent
With regard to biological evolution, which of the following statements is incorrect? Explain why.A. During its lifetime, an animal evolves to become better adaptedto its environment.B. The process of biological evolution has produced species thatare better adapted to their environments.C. When an animal is better adapted to its environment, the process of natural selection makes it more likely that the animalwill reproduce.
What is Mount Improbable in Richard Dawkins' concept of evolution? a) A physical mountain where organisms evolve to survive at high altitudes b) A metaphorical mountain representing the difficulty of evolving complex adaptations c) A hypothetical location where new species originate d) A mountain range where convergent evolution occurs
Imagine that you have the DNA sequences fromthe intron of a gene in three species called A, B,and C. Species A and B are most closely related,while C is more distantly related. The sequencesof A and B differ by 18 base pairs, A and C differby 26 base pairs, and B and C differ by 28 basepairs. Fossils show that species A and B divergedabout 1.2 Mya, but there is no fossil evidence asto when the most recent common ancestor ofall three species lived. Use the genetic data toestimate that date. What assumptions are youmaking to get this estimate?
A scientist is attempting to a cladogram that shows the evolutionary closeness of three organisms in relation to humansAfter doing DNA analysis, they that the organisms share the following percentages of DNA Organism A and humans share 85% of their DNA Organismn and humans share 80% of their DNA Organism and humans share 90% of their DNA Based on informationwhich order should they go on the cladogram ( related to most related ?
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.
Which pattern of evolution is more likely to introduce homoplasies in the relationships between species?A) divergent evolutionB) parallel evolutionC) convergent evolution
Researchers have found fossils of Eocene horse species in Colorado. Deeper deposits contain smaller species, and more recent deposits contain larger species. How does this observation support the theory of evolution? A. It provides evidence that species change over time. B. It does not support the theory of evolution. C. It shows that all species are related to each other. D. It proves that environments have changed over time. E. It suggests that species are unchanging and of recent origin.
Darwin’s finches are a noteworthy case study of evolution by natural selection because evidence suggests a. they are descendants of many different species that colonized the Galápagos. b. they radiated from a single species that colonized the Galápagos. c. they are more closely related to mainland species than to one another. d. None of the choices is correct.
Biological evolution is best defined as A. the process of direct observation B. unchanging nature of life on earth C. change in a populations' genetic charteristics over time D. adaptations to common decent
