Chapter 8 Evolution 2024-2025

Significant genetic similarity between the two organisms.

Seedless vascular plants evolved before gymnosperms and angiosperms.

By comparing gene sequences, we can identify which species are most closely related.

Some bacterial variants can survive and reproduce, leading to antibiotic resistance.

The lighter-shaded moths will be selected out of the population.

Evolution is the process by which species change over time through genetic variation and natural selection.

Natural selection is the mechanism by which individuals with favorable traits are more likely to survive and reproduce.

A phylogenetic tree is a diagram that shows the evolutionary relationships among various biological species.

Fossils provide evidence of past life forms and their changes over time, helping to trace evolutionary history.

Genetic drift is a change in allele frequencies in a population due to random sampling of organisms.
