The scientist is studying how long it took for a single ancestral population of chimpanzees to become two distinct species, common chimpanzees (Pan troglodytes) and bonobos (Pan paniscus). Which scenario would likely have resulted in the fastest rate of speciation of the common chimpanzee and bonobo? Two small ancestral populations existed A with the same environmental conditions. Two large ancestral populations existed with the same environmental conditions. Two small ancestral populations existed with different environmental conditions. Two large ancestral populations existed D with different environmental conditions. B

What causes convergent evolution resulting in two species, distantly related from each other to have similar adaptations (such as birds and bats)? A Hybridization of two different species to produce an offspring with traits of both parents. B Similar environmental pressures Mutations Similarities in DNA

A population of 600 scorpions was split into four populations when irrigation canals were built through their habitat. The four new populations were called the Northern, Southern, Eastern, and Western populations. Each new population consisted of about 150 individuals. The four populations continued to evolve, and no migration occurred among populations. One hundred generations later, each population still has about 150 individuals, and a biologist investigates them.  Consider what a biologist expect to see in the four populations after 100 generations if the environment did not change for any of the populations. Would the biologist agree or disagree with the following statements?  a) In the smaller populations of 150 individuals, the processes leading to genetic drift could have a stronger influence on a gene than natural selection. agree or disagree b)Chance survival of some individuals occurred in some generations, but not every generation. agree or disagee c)Beneficial mutations…

How is sympatric speciation different from allopatric speciation? Group of answer choices Allopatric speciation requires a geographic barrier, while sympatric speciation occurs in one place Allopatric speciation results in hybrids, while sympatric speciation does not Allopatric speciation is a result of behavioral isolation, while sympatric speciation is a result of habitat isolation Allopatric speciation occurs in one place, while sympatric speciation requires a geographic barrier
