Common genetic ancestors lived during roughly same time period

Mitochondrial Eve and Y-chromosomal Adam -- two individuals who passed down a portion of their genomes to the vast expanse of humanity -- are known as our most recent common ancestors, or MRCAs. But many aspects of their existence, including when they lived, are shrouded in mystery. Now, a new study indicates the two roughly overlapped during evolutionary time: from between 120,000 to 156,000 years ago for the man, and between 99,000 and 148,000 years ago for the woman.
