The new trait appears in a group of previously isolated people is an
example of genetic drift.
<h3>What is Genetic drift?</h3>
This is defined as the random fluctuations in the frequencies of alleles
from generation to generation due to occurring events which makes the
trait to be present or disappear.
The new trait appearing as a result of events such as migration helps to
infer that it is genetic drift.

Organisms that are characterized by being unicellular, photosynthetic, and having double shells made of silica are known as B. diatoms.
<h3>Photosynthetic</h3>
By converting light energy into chemical energy through a process called photosynthesis, plants and other living things can subsequently release that chemical energy to power their activities. The name "photosynthesis" comes from the Greek words "phs" for "light" and "synthesis" for "putting together." Some of this chemical energy is stored in carbohydrate molecules like sugar and starch, which are created from carbon dioxide and water. These creatures are referred to as photoautotrophs and include the majority of plants, algae, and cyanobacteria. Most of the energy required for life on Earth is produced and maintained through photosynthesis, which also produces and maintains the oxygen concentration of the atmosphere.

The correct answer is glycolysis.
Glycolysis is an anaerobic process of splitting a molecule of glucose (6 carbons) to 2 molecules of pyruvate (3 carbons each). Glycolysis does not require the presence of oxygen and will still produce energy, albeit lower than aerobic metabolism. In the absence of oxygen, fermentation can occur wherein pyruvate is further converted into lactate.
