THE WORLD/SCIENCE (Naked Departure) — EVOLUTION — AFRICAN elephants are being born without tusks due to poaching, researchers say. An increasing number of African elephants are now born tuskless because poachers have consistently targeted animals with the best ivory over decades, fundamentally altering the gene pool.
In some areas 98 per cent of female elephants now have no tusks, researchers have said, compared to between two and six per cent born tuskless on average in the past. (Source: Dawkins)
If elephants can do this, why didn’t African DNA change deterministically/evolve in response to centuries of slavery? Naked Departure
