Discover the meaning of genus, a key rank in biological taxonomy that groups together closely related species. Learn its importance in science.

An introduction to taxonomy, the science of classifying living organisms, and its critical importance in conservation, medicine, and research.

Discover homologous structures, the similar anatomical features in different species that point to a shared common ancestor and divergent evolution.

Discover the kingdoms of life, the highest level of biological classification. Learn how scientists organize everything from bacteria to animals.

Dive into Animalia, the vast biological kingdom of all animals. Explore the diversity, classification, and importance of these incredible life forms.

Discover the fossil record, the Earth's diary written in stone. Learn how these ancient remains reveal the history of life and evidence for evolution.
