103.   Scientists disagree whether they were the ancestor of modern humans or a related but different species.

104.   Some DNA has been recovered from ancient bones, he said, and researchers in Sweden are attempting to compare gene fragments from Neanderthals to that of modern humans.

105.   Such information could be central to the understanding of where and how modern humans, Homo sapiens, evolved, the newspaper said.

106.   The ancestors of modern humans were more than tree-climbing plant-eaters, according to a new study.

107.   The researchers said they are not certain if the remnants were left by Neanderthals or modern humans.

108.   The scientists speculate that the gene might have been active long ago in evolution but then turned off, leaving modern humans with much less facial hair.

109.   They are also a blow to the theory that modern humans evolved simultaneously in Africa, Europe and Asia from multiple early humans.

110.   They said it might be the oldest evidence outside Africa of the evolutionary group called Homo, which includes modern humans and close ancestors.
