Answer:

Genetic drift

Explanation:

Genetic drift is an evolutionary mechanism that in a population it changes allelic frequencies over generations just by chance. For this reason, small populations are more susceptible to be affected by genetic drift than bigger populations.  

In this example, Indiana Jones visited a small village of 50 people and over generations allele A probably was lost just by chance, or by genetic drift.

Pseudoscience may sometimes permit personal opinions as evidence.

<h3>What is pseudoscience?</h3>

The term pseudoscience refers to the reliance on logical explanations rather than empiricism to explain the observations in the universe. We know that science is empirical and results must be reproducible.

It is important to emphasize that the difference between science and pseudoscience is that science has an emphasis on empiricism and experiments are the only way that we could validate. Most of the earliest approaches to the study of the universe depended on pseudoscience.

The study of the natural world is the concern of both science and pseudoscience. The explanations in pseudoscience may sound logical but the results generated by science can be tested by others. The explanations of science can be proven false.

Lastly pseudoscience may sometimes permit personal opinions as evidence.
