Ribosomes make proteins inside a cell.
The right option is; extreme traits
Disruptive selection events select for extreme traits.
Disruptive selection is a type of natural selection in which organisms with extreme traits are favored (such as in reproduction) over organisms with intermediate traits. This type of selection results in increased traits differences with increase in frequency of the alleles for the extreme traits. Disruptive selection can lead to the digression in a species line.
Fossils are physical evidence of preexisting organisms, either plant or animal. ... Fossils of any kind are useful in "reading the rock record," meaning they help us decipher the history of the earth. They can help us determine the geologic age and environment (the paleoenvironment) in which they were deposited.
