Life on Earth began in a way that still boggles the mind. Around 4.5 billion years ago, a chemical process called abiogenesis occurred, where life emerged from non-life. Imagine a hot, watery mix of ...

Human evolution spans millions of years, from early primates to modern Homo sapiens. Fossil evidence, genetic data, and climate shifts help explain how different human species emerged, migrated, and ...

The human body is a machine whose many parts – from the microscopic details of our cells to our limbs, eyes, liver and brain – have been assembled in fits and starts over the four billion years of our ...

Human evolution has long been tied to growing brain size, and new research suggests prenatal hormones may have played a surprising role. By studying the relative lengths of index and ring fingers — a ...

Humans' exposure to high temperature burn injuries may have played an important role in our evolutionary development, shaping how our bodies heal, fight infection, and sometimes fail under extreme ...

Researchers at the University of Maine are theorizing that human beings may be in the midst of a major evolutionary shift—driven not by genes, but by culture. "Human evolution seems to be changing ...

If we look across the whole of the mammal branch of the tree of life, we find there are many groups of mammals that have ...

Scientists find clue to human brain evolution in finger length: Study ...
