How do mutations in the DNA code impact real life?

A mutation happens by chance it cause by the rna polymerase copying the wrong piece of code from your dna leading the wrong protein to be made.

This could either be beneficial or not as it causes variation in a species helping them evolve becuase of survival of the fittest or threatening extinct of the entire specise if their environment has changed as it could threat their survival therefore having variation with in species could help increase their survival rate

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.
