  • A bastard seal from the past reveals the potential for human hybrids
    on November 30, 2018 at 4:16 pm

    If discovered as fossils, grey and ringed seals are so different that they could be classified as belonging to different families. Yet, a seal pup born in 1929 was found to be an almost perfect intermediate between the species. Compared to Neanderthals and modern humans, grey and ringed seals are genetically and dentally at least twice as different, suggesting that there may be more fossil human hybrids to be discovered. […]
