In biology, a ring species is a connected series of neighboring populations that can interbreed with relatively closely related populations, but for which there exist at least two "end" populations in the series that are too distantly related to interbreed. Often such non-breeding-though-genetically-connected populations co-exist in the same region thus creating a "ring". Ring species provide important evidence of...

But many archaeologists still talk of cultural revolutions associated with our kin (and not the others) and many palaeoanthropologists have continued to insist that we are a different species (Homo sapiens) from them (Homo neanderthalensis).

More than 35,000 new species of flowering plants may be lying undiscovered in cupboards around the world, it is claimed. Botanists looked at how long it takes for new species collected in the field to be identified, and found it often took decades. They concluded that of the 70,000 flowering plants that experts believe are yet to be found, over half may already be in collections, awaiting identification.

Not so very long ago, we shared this planet with several other species of human, all of them clever, resourceful and excellent hunters, so why did only Homo sapiens survive?

The natural world contains about 8.7 million species, according to a new estimate described by scientists as the most accurate ever. But the vast majority have not been identified - and cataloguing them all could take more than 1,000 years. The number comes from studying relationships between the branches and leaves of the "family tree of life"...

Neanderthals were already on the verge of extinction in Europe by the time modern humans arrived on the scene, a study suggests. DNA analysis suggests most Neanderthals in western Europe died out as early as 50,000 years ago - thousands of years before our own species appeared. A small group of Neanderthals then recolonised parts of Europe, surviving for 10,000 years before vanishing.
