Many people are familiar with the concept of natural selection and “survival of the fittest.” While modern humans may look like they’ve been at their “fittest” for hundreds of thousands of years, new ...

Natural selection has long been considered the driving force behind human evolution. But a landmark study of 87 fossil skulls spanning the past two million years suggests the story is far more complex ...

Learn how repeated burn injuries may have acted as a form of natural selection, influencing human genes linked to healing and immune response. Fire transformed human society in obvious ways. Less ...

Some scientists say humans may be entering a new phase of evolution, one in which culture is becoming more powerful than genes in shaping our survival and future. At the heart of that idea is a ...

Some researchers hold that evolution hasn’t much altered humans in the past 10,000 years. A new analysis of ancient DNA indicates that natural selection continued to shape hundreds of genes. By Carl ...

For more than a century, scientists have sought to reconstruct human evolution using diverse lines of evidence, including fossils, genetic variation across populations, and ancient DNA. Building on ...

Throughout most of human history, evolution progressed slowly. Small genetic changes took thousands of years to permeate populations. Natural selection was intentional, reactive, and gradual. However, ...
