Definitions:

Natural Selection

Natural selection is a mechanism that can lead to adaptive evolution, whereby differences in the phenotypes of individuals cause some of them to survive and reproduce more effectively than others and therefore outcompete them.

Synapomorphy

A characteristic or trait that is shared by two or more taxonomic groups and is derived from their most recent common ancestor, indicating a phylogenetic relationship.

Molecular Phylogeny

The analysis of the molecular structure of DNA, RNA, or protein sequences to determine genetic relationships and evolutionary histories among different species.

Amino Acids

Organic compounds serving as the building blocks of proteins, crucial for life and involved in various metabolic processes.
