We often think of microbes as organisms that live around us, like the Salmonella bacteria and flu viruses that cause illness. But some of our most intimate relationships are with the microbes living ...

A microorganism whose evolutionary roots can be traced to the era of the first multicellular animals may provide a glimpse of how single-celled organisms made a critical evolutionary leap. In ...

Paleorex is back on Bored Panda with his detailed, science-based creatures, showing us how animals like big cats, birds, and reptiles might evolve in the future. In this article, we’re featuring even ...

Islands act as fascinating evolutionary labs where isolated animal populations can flourish. Over countless generations, these creatures adapt, resulting in extraordinary traits and unique species.

A sweeping analysis of thousands of animal genomes suggests that chromosomes do not evolve randomly but instead follow a limited number of irreversible “evolutionary highways.” These one-way genetic ...

A series of whole genome and gene duplication events that go back hundreds of millions of years have laid the foundations for tissue-specific gene expression, according to a new study. The 'copy-paste ...

New research suggests ancient feces helped fuel marine life during the Cambrian Explosion.

In most narratives, the story of evolution is the story of organisms emerging from the ocean and eventually populating the land. But for some species, that evolution also involved a return trip.

By examining thousands of genomes along with fragments of ancient chromosomes, researchers uncovered the intricate journey of ...

Embryonic germ layers are the fundamental organizing principle in animal development. They provide the structural basis from which tissues and organs arise. During early embryogenesis, cells divide to ...
