Question

What are the five causes of evolution?

Answer 1

Causes of evolution:

1. Gene Duplication:

1. This is a duplication of a specific DNA region.
2. It arises as a result of recombination, aneuploidy, transposition, polyploidy, and replication errors in DNA.

2. Modular Components:

1. This is a DNA segment that may be introduced into any part of the genome.
2. The most prevalent transposable element identified in humans is aluminium.

3. Mutation:

1. Genome alterations are caused by random mutations.
2. The nucleotide sequence changes, causing a frameshift mutation in the DNA.
3. Prokaryotes are the most prone to this.

4. Exon's Reshuffle:

1. Two exons from distinct genes join together during this period.
2. New genes are responsible for this process.
3. As a result, the genome gains a new gene.
