Since modern humans left Africa around 50,000 years ago, ancient DNA from Neanderthals and early modern humans revealed that the two groups actually interbred somewhere in the Near East. As a result, anyone outside of Africa carries about 2% to 3% Neanderthal DNA. Those Neanderthal DNA segments grew progressively shorter in modern human genomes over time, and their length can be used to approximate when a person lived.
Furthermore, archeological evidence released last year indicates that modern humans were already present in southeastern Europe 47-43,000 years ago. However, nothing is known about who these early human colonists were - or their connections to ancient and modern human communities - owing to a shortage of reasonably complete human fossils and the absence of genomic DNA.

The discovery in 1938 of a living coelacanth of South Africa s coast was quite a shock, as it was thought that these species were extinct. Thanks to their eerie similarity to near-identical creatures spotted in the fossil record, the big fish were eventually referred to as living fossils.
A recent study published in Molecular Biology and Evolution reveals that at least one genus of the coelacanth, formally referred to as Latimeria chalumnae, is not the living fossil it is thought to be, having gained hundreds of new genes over the past 23 million years, a startling discovery and a far cry from the belief that the species has hardly evolved since its ancestors appeared over 300 mi Moreover, the discovery is further confirmation that the idea of living fossils is obsolete and something of a misnomer.
