Summary Introduction
To explain: Whether the statement “Most species that evolved have already become extinct” is true or false.
Introduction: Extinction is a process of termination of one species or group of species. The species formed get extinct on an ongoing basis.

Would it be possible to bring extinct species back?
In an article it was expressed how brinng extinct species back is still very futuristic, and we should aim at a smaller creature. Using a smaller sized species like the Christmas rat can set up scientists for potentially larger species. There is a major issue that comes up and that is incomplete genes. It makes it difficult to even compare modern day rat to the Christmas rats' genome because their genes are specialized and as more time passes, the harder it is to have a match. The article also talked about using modern day elephants to make a woolly elephant, meaning they don't want a perfect match. Rather, scientists want to make hybrids since it could be more realistic.
The evolution of one species into two or more species as a result of different populations becoming reproductively isolated from each other is best termed as adaptive radiation. True or False.
Before humans began altering the natural world. The number of species on earth remain stable through geological time true or false,

- Since different species may occupy the same habitat, explain why they continue to remain separate species? Adaptive radiation is when populations diverge from a common ancestor into new species, each of which is adapted to its own unique niche.
