Darwins Big 3

Biological evolution, Natural selection, Common Descent

Natural Selection

Variation, Inheritance, and Differential survival/ reproduction

Artificial Speciation

The process by which new species are created through artificial means, often involving selective breeding or genetic manipulation.

Sexual Selection

A form of natural selection where certain traits increase mating success, influencing the evolution of species.

Genetic drift

Random changes with no advantage; driven by chance rather tha events.

Speciaition

The evolutionary change that divides a group of organisms seperating them into diffferent resulting in evolution of a new species

Character

a trait (shape, gene, or behavior)

Synapomorphy

shared or derived character

Homologus

inherited from a common ancestor

Plesiomorphy

ancesterial trait (passed down trait)

synamorphy

evolved trait

convergent

evolved independently

divergent

evolved frpm a common ancestor
