Female African elephants in Mozambique's Gorongosa National Park have been born without their ever-crucial ivory tusks, and scientists are saying it's an evolutionary result of the brutal poaching and killing of the animals during the country's civil war.
According to new research released Thursday in the journal, Science, between the years of 1972 and 2000, elephants born without tusks – almost all female – tripled in number. In Gorongosa in the 1970s, 18.5% of female elephants didn't have tusks. Now that number is 51%. Analysis from the study revealed that tuskless elephants are five times more likely to survive.

Why are tusks crucial?
Tuskless elephants is not a new mutation. It was already present in the population.staff edut
I did. I didn't see it. I apologize.Read the article, your question is answered there.
And for some reason the tuskless males are are miscarried.
It's not just a question of time, the nature and severity of the selection pressure is important.Yet in that same time period human selective pressure on elephants has had an effect. Does the study address how the mutation rate in elephants makes this possible as opposed to species such as homo sapiens where it is not possible?
