Imagine that part of a population of south american finches is blown by a storm onto an island far offshore and manages to survive and reproduce there for a period of 10,000 years. after that period, a climate change results in lower sea levels and the reconnection of the island with the mainland. members of the formerly isolated island finch population can now interact freely with members of the original mainland population.
which of the following observations would, by itself, lead you to conclude unequivocally that the island finch population had evolved into a distinct species, according to the biological species concept? a) individuals from the different populations sometimes mate with each other, but all of the resulting eggs are sterile. b) the island birds all have red feathers, but the mainland birds have green feathers. c) hybrid offspring of matings between individuals from the two populations do not look like either parent. d) the preferred food of the island birds is quite different from the diet of mainland birds. e) individuals from the different populations frequently direct courtship behavior toward members of the other population.

In 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? in 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? staphylococcus aureus bacteria that were able to synthesize cell walls using a protein that was not affected by methicillin survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, some bacteria began to synthesize cell walls using a protein that was not affected by methicillin. these bacteria survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, bacterial populations gradually began to synthesize cell walls using a protein that was not affected by methicillin.
