What was the first species to be extinct?
The first life on earth was unicellular organisms. These organisms reproduced asexually, meaning that they reproduced by copying themselves. Because they did not interbreed, a slight mutation in the DNA caused a new species to exist. If one of the mutant cells failed to divide, that was a species becoming extinct. Humans cannot even begin to fathom the number of these species there must have been or when they started to become extinct. Extinction is a natural process and cannot be stopped; when we talk about being concerned about extinction we generally mean extinctions caused by modifications made to the environment by humans.
