How does DNA replication affect evolution?

Can you explain how DNA replication influences evolution?

DNA replication is crucial for evolution as it ensures genetic information is passed on. Errors during replication can lead to mutations, which are a primary source of genetic variation.

What kind of mutations can occur during DNA replication?

Mutations can be point mutations, insertions, deletions, or duplications. These changes can affect an organism's traits and potentially lead to evolutionary changes.

Are all mutations harmful to an organism?

Not at all! While some mutations can be harmful, others can be neutral or even beneficial, providing advantages that may enhance survival and reproduction.

How do beneficial mutations spread through a population?

Beneficial mutations can spread through a population via natural selection, where individuals with advantageous traits are more likely to survive and reproduce, passing those traits to the next generation.
