Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

A potted scarlet monkeyflower would die within a few days without water. But multiple natural populations of the species ...

An analysis of ancient and modern DNA suggests the extent of convergent evolution in different peoples around the world is ...

Understanding biological relationships is often critical when studying animal populations. Researchers have now developed a transformative approach that identifies stretches of DNA that two ...

Volcanic eruptions on the remote island of Nishinoshima repeatedly wipe the land clean, giving scientists a rare chance to study life’s earliest stages. Researchers traced the genetic origins of an ...

When the worst drought on record struck parts of the US West Coast and Mexico, many plants didn’t make it. But against the odds, the scarlet monkeyflower managed to weather the hardship and continue ...

A recent groundbreaking study has radically altered our understanding of human evolution. Homo sapiens, traditionally thought to have descended from a single lineage, is now believed to be the product ...

Wild scarlet monkeyflowers in California survived a historic drought by relying on a rapid evolution, marking the first time the process has been observed in the wild.

Genetics helped scarlet monkeyflower rebound after California’s megadrought — a real‑world example of rapid evolution.
