Answer:
C) Population bottleneck reduced genetic diversity, as the gene pool of the 30,000 elephant seals resulted from the few alleles present in the 20 bottleneck survivors.
Explanation:
<u>The correct answer would be that population bottleneck reduced genetic diversity, as the gene pool of the 30,000 elephant seals resulted from the few alleles present in the 20 bottleneck survivors.</u>
A sudden decrease in the population of an organism as a result of disaster or any other factor leads to a population bottleneck - a decrease in the genetic variability of the population.
<em>The decrease in the available number of alleles in the population limits the amount of genes that natural selection can influence. Hence, as the population keeps increasing, the genetic diversity of the entire population rarely changes because the few alleles present in the population keep recombining.</em>
The correct option is C.
Answer:
The fossils gradually drifted apart over a long period of time
Explanation:
Although a single human was not able to witness it since the earth's plates shift slowly, the fossils eventually seperated over the course of tens of millions of years.
The first serious attack on the idea of spontaneous generation<span> was made in 1668 by Francesco Redi, an Italian physician and poet. At that time, it was widely held that maggots arose </span>spontaneously<span> in rotting meat. Redi believed that maggots developed from eggs laid by flies.</span>
