The elephants of the Garongusa National Reserve were slaughtered for ivory during the 16-year war that ended in 1992, but one-third of the women of the next period formed a toothless generation or were became much smaller than she had been before. Attractive for fishermen, according to the website "Daily Mail".
"Elephants target big elephants, so the disappearance of the gene that is responsible for them is a way of life for these animals," said Dominique Damele Correa Gonzalez, environmental and wildlife specialist. "Elephants and females are usually born with canines up to 10 feet.
She explained that the development of elephants in this way is due to the fact that their offspring belong to their members who survived the fishing during the war, because of the small teeth that mated later and transmitted this attribute to his children resulting in the disappearance of the gene responsible for big fangs over time.
Scientists also believe that female elephants have developed aggressive behavior towards humans because of their need to defend their young. "The behavior of elephants today is very interesting because it is recent," Dominique said. "Testimonials from people who lived in this region before the war, That elephants were silent and do not care about the existence of human beings.
Evolutionary scientists at the University of California are studying elephant blood samples today to determine the effect of genes on the absence and smallness of fangs, and why they are more pronounced in women than in men and also affect their behavior.
"Elephants use their teeth to dig in search of water or food, which means that the lack of fangs can force them to go further to survive, which affects their natural species," explains Ryan Long, ecological behavior specialist. Human beings on the ecosystem ".
