This is when mating occurs between members of the species with undesirable traits for survival, or when two different species mate and create an infertile hyb liberateization breed. In other words, reverse evolution. .
There are also different types of extinction. Mass extinction is when almost all of the species are wiped out, such as what we expect happened to the dinosaurs with meteor destruction. Co-extinction occurs when one species becomes extinct because another species becomes extinct. This often happens to parasite species when their host becomes extinct. Modern extinction or Holocene extinction is extinction caused by human interaction.



These are human activities like pollution, over-harvesting, and habitat destruction. Humans also are responsible for planned extinction. This is often an effort to conduct rid of viruses and bacteria that threaten our lives.
One of the greatest threats of extinction at present is global warming. It has been estimated that within the next forty years, between xv and thirty-seven percent of our land species could face extinction.
The vast majority of human beings probably do not realize how near extinction is. Most of us think of dinosaurs when dateing animals that have become extinct. Perhaps, it would help put it in better perspective to consider the species that have become extinct in this century. The...If you want to get a full essay, order it on our website: Orderessay
