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.

When populations groups diverge, whether they're separated geographically, temporally, or behaviorally, they find themselves on the pathway to speciation.

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.

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 te…

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.

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 prote…

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.

New DNA molecules are generated through a complex replication process, and mutations can be repaired with a variety of mechanisms.

The genome encodes information to 'build' the organism; the process of transcription encodes the DNA information into RNA, and translation encodes the information into polypeptide chains, which form …

Meiosis is a specialized form of cellular replication, which creates many haploid daughter cells, each possessing a single copy of the genome.

A brief introduction to genetics, including the structure of DNA and RNA, gene expression, genome replication, and more.

As organisms a born, grow, reproduce, and die, so too do cells. The cell cycle is the pattern of cellular growth & replication that sustains life.

The cell is one among many; all cells in a tissue, or an organ, or an organism, have relationships with other cells, and these relationships help to sustain life.

Cellular respiration is a perpetual cycle of energy generation that sustains not just the cell, but the life of the organism it's a part of.

Enzymes are among several diverse groups of chemicals that participate in the metabolic pathways that keep the cell alive.

The cell perpetuates itself with a variety of organelles, metabolic pathways, and biochemical subsystems.

A brief introduction to the cell, including its structure, physiology, metabolism, and replication.

The lipids are fundamental building blocks of life, as they can store energy for the long-term, and they compose the cellular membrane.

The carbohydrates are carbon-rich molecules that can do many things, from storing energy, to supplying carbon atoms for molecular synthesis.

The nucleic acids are fundamental building blocks of life, forming the basis for countless derivative compounds, and the monomers of DNA.
