Male bowerbirds construct elaborate nests in order to attract females. Different species of bowerbirds often live in the same area, yet they will not mate with each other because of the females' strong preferences for a particular kind of nest. What does this exemplify? convergent evolution reproductive isolation homologous structures geographic isolation

Males of different species of the fruit fly Drosophilathat live in the same parts of the Hawaiian Islandshave different elaborate courtship rituals. These rituals involvefighting other males and making stylized movements thatattract females. What type of reproductive isolation does thisrepresent?(A) habitat isolation(B) temporal isolation(C) behavioral isolation(D) gametic isolation
Consider two species that diverged whilegeographically separated but resumed contactbefore reproduction isolation was complete. Predictwhat would happen over time if two species matedindiscriminately and a. hybrid offspring survived and reproducedmore poorly than offspring from intraspecificmating or b. hybrid offspring survived and reproduced aswell as offspring from intraspecific mating.Provide an example for each to illustrate yourpoint.
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.
What is the nature of the reproductive barrier between a species that mates at dawn (sunrise) and a species that mates at dusk (sunset)? gametic temporal habitat behavioral mechanical A mountain range divides a freshwater snail species into two isolated populations. Erosion eventually lowers the range and brings the two populations together again, but when they mate, the resulting hybrids all produce sterile young. This scenario is an example of allopatric speciation gradualism punctuated equilibrium extinction sympatric speciation
Adaptations B Fossils Ancestral structures Homologous structures 2. The process by which individuals that are better adapted to their environment are more lik to survive and reproduce than other members of the same species is called Natural selection Evolution C Competition Over production 3. Which of the following is the best example of an adaptation that helps organisms surviv their environment? A green coloring in lizards living on gray rocks B. a thick coat of fur on animals that live in the desert an extensive root system in desert plants
The Abert and the Kaibab species of squirrels live on opposite ends of the Grand Canyon. Physically they are very similar to each other, which leads scientist to think that when the Grand Canyon was shallower (millions of years ago) the populations use to have genetic contact (sexual reproduction). In present day, they are completely isolated from each other. When tested the Abert and Kaibab squirrels cannot produce a fertile offspring. This is an example of ___ speciation. [Fill in the blank]
