Episode 23 - Phylogenetics
As all living things are fundamentally related, phylogenetics is the study of these genetic relationships, and the evolutionary history of the many diverse lineages of Earthly life.

Episode 22 - Divergence & Speciation
When populations groups diverge, whether they're separated geographically, temporally, or behaviorally, they find themselves on the pathway to speciation.

Episode 21 - Mechanisms of Evolution
Besides natural selection, evolution is influenced by mechanisms like gene flow, the random walk of genetic drift, and the novelty-generating phenomenon of genetic mutations.

Episode 20 - Natural Selection
The forces of natural selection remove from the gene pool those lineages too unfit to survive in a given habitat, while those with good health survive to make healthy offspring, and their lineages ten...

Episode 19 - Introduction to Evolution
A brief introduction to evolution, including its mechanisms, selective pressures, runaway effects, and the fundamental importance of evolution as a guiding force for the perpetuation of life.

Episode 18 - Gene Modification
Genetic information is complex; there's the gene sequence, the regulation of gene expression, and there are even mechanisms to modify genes, allowing a single gene to produce multiple different protei...

Episode 17 - Gene Expression
The gene itself encodes raw information, but this is just the beginning of gene expression, which is a complex, highly-regulated, and tightly-coordinated process.

Episode 16 - DNA Synthesis & Repair
New DNA molecules are generated through a complex replication process, and mutations can be repaired with a variety of mechanisms.
