Answer;
Genetic drift
The mechanism of evolution that would have caused this change is genetic drift.
Explanation;
Genetic drift refers to changes in allele frequencies due to random chance. Genetic drift will eventually lead to allele loss or fixation even in large populations, but will take many more generations to occur in large populations than small. It may rapidly alter allele frequencies when population size decreases; bottle neck effect and founder effect.
Answer: <u>Option A point source pollution
</u>
Explanation: The pollutants which can be tracked, from the source of origin are termed as point source pollution. This can be water source, air or even light or noise pollution. The pollutants are easily detected being released from the source of pollution. Whereas the non-point source of pollution are those which are indirect sources and they carry off the pollutants which lie on the way, like runoff water carrying the pesticides from the agricultural land.
