Answer:
Testing positive for HIV means a high chance of death and a good chance of lower reproduction rates. But some people are immune to HIV, which makes them more evolutionarily fit, likely to live longer, likely to reproduce more, which would increase the frequency of the immune allele in the population. Over time, this increase in frequency of the gene that causes immunity could spread across the human race and cause it to evolve.
<u>Answer:</u>
An example situation of artificial selection is "More African elephants today naturally lack tusks compared to the elephant populations 100 years ago, because big game hunters sought elephants for ivory".
<u>Explanation:</u>
- The process of breeding animals to acquire the desired characteristics by the external means other than natural selection and behavior of animal itself is called as artificial selection.
- The first artificial selection was carried out by Darwin when he mated penguins that would have a higher chance of breeding.
- The practice of artificial selection was existing in human civilization a long time ago.
