Fossils are the preserved remains of previously living organisms or their traces, dating from the distant past. Fossils that have been collected offer unique insights into evolution over long timescales. However, fossils have some limitations. Select ALL the limitations
of using fossils as evolutionary evidence.
es )
A)
Fossils do not exist for large animals.
B)
Fossils only form in areas once covered by water.
Plate tectonics causes loss or displacement of fossils.
D)
Most organisms never fossilize, leaving holes in the fossil record.
E)
Because marine fossils are prevalent, this can lead people to believe they
were more dominant than they actually were

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.
