Answer:
O founder's effect
Explanation:
A founder effect can be defined as the loss of genetic variation when a new population is established from a few individuals. This process is known to increase the frequency of particular gene variants (alleles) at different <em>loci</em> when they are selectively neutral (or nearly neutral), and thereby such genes are fixed by genetic drift (i.e., through the random sampling of founder individuals). Interestingly, it has been discovered that the majority of South American and Central American Indians are nearly exclusively in the O blood group, which has been further associated with random genetic drift and a founder effect.

If we could see your choices, it would better help us to help you.
Explanation:
But, if you are referring to the most widely accepted theory:
Anthropogenic (man-made) Global Warming, or AGW. The theory states that man-made greenhouse gases, primarily carbon dioxide (CO2 ), are the predominant cause for the global warming that has occurred during the past 50 years.
I neeeed help on the question too
As a mollusc, the animal probably has a mantle and a radula.
Molluscs are aquatic species that belong to the phylum of Mollusca. Mollusca is one of the biggest and most diverse phyla of the sea.
A mantle is a term that describes the fold in their body which secretes the hard protective shell of their body. A radula is a toothed structure (similar to the tongue) used to collect food.
