Transposable elements are DNA sequences that contain numerous point mutations. Thus, option "4" is correct.
<h3>What are Transposable elements?</h3>
Transposable elements are fragments of DNA that have the ability to jump from one part of the genome to another. While most of the DNA is always in the same place surrounded by the same neighbouring pieces of DNA, mobile elements move from one place to another causing many changes or mutations.
When a transposon moves through the genome, it can insert into a vital gene, disrupting its function, or into a location near vital genes, causing erroneous activation or inactivation.
On the other hand, there can be chromosomal rearrangements due to transposons of the same family with complementary sequences that are separated in the genome and that by sequence homology match.
This can lead to ectopic recombination. Large-scale rearrangements induced by mobile elements are considered a particular class of recombination events that influence genomic plasticity.
Thus, option "4" is correct.

Answer:
The video says that Tibetan people from birth have higher oxygen saturation due to evolution.
The video says that people in Siberia and the high arctic have adapted to survive extreme cold.
I think that one evolution that could be beneficial to humans is the ability to have more tougher skin because our skin doesn't have too many layers.
