Elephants are starting too evolved thanks to the threat of poachers. Now in days elephants are being born with shorter or no tusks. Poachers killed the elephants for their tusks because they are valuable to them. What poachers do not understand is that tusks are important to the elephants. Tusks are used to dig up food and water, to dig up trees and branches and moved them around. Tusks can also be used for self defense and for sexual display. Male elephants in China will be born without tusks because the poaching of the species is reducing the gene pool. To help preserve their species elephants are losing their tusks as fats and effective evolutionary response to escape being killed. This is a result of a chance genetic mutation. Since only male elephants have tusks they are being killed rapidly. For every ten females there is only one male. The tusk less elephants are an adaptive trait because poachers will not be able to killed them. They know in order to survive they must not have any tusks otherwise they will get killed. Therefore, they willed be able to survive and increase their numbers. A maladaptive trait would be because they are tusk less the elephants could die if they do not know get uses to being without tusks. An example of speciation is the bears. There used to be only the brown bear but then some bears moved north and their color lighten and now they are white instead of brown. Extinction would be the dinosaurs. Millions of years ago they had roam this earth and now they are gone. There were many speculations and one is that they were hit by an asteroid.
