Biologists are quietly rewriting what it means to be alive, and the human body has become one of their strangest frontiers.

Humans make stuff up—including the names and classifications of living things. But those categories are still useful. In this episode of Crash Course Botany, we’ll explore how taxonomy and systematics ...

Life and death are traditionally viewed as opposites. But the emergence of new multicellular life-forms from the cells of a dead organism introduces a “third state” that lies beyond the traditional ...

Fish, flies and bears, oh my! A new research breakthrough gives genetic proof of how differences in (very different) animals develop. An international team of biologists has identified the molecular ...

Children are taught that all living organisms -- from animals, plants, and fungi to bacteria and single-celled organisms -- belong to specifically different categories of organic life. A new discovery ...

The history of life stretches back untold eons. Today, there is a staggering array of organisms on Earth, with more species being discovered every year. The complexity of life, from the smallest ...
