LOS ANGELES — A 50,000-year-old toe bone found in a Siberian cave is giving scientists a surprising view of the breeding habits of early humans.

In what has been described as a "Lord of the Rings"-type world, researchers say that Homo sapiens, Neanderthals and two other groups of early humans mingled and interbred thousands of years before all species but ours became extinct.

The findings were presented Wednesday in the journal Nature by a team of scientists who sequenced the DNA from the Neanderthal toe fossil and compared it to the genomes of 25 present-day humans, as well as the genome of a sister group to Neanderthals called Denisovans.
