Biologists reported that crossbreeding  is more common  than previous statement

Explanation:

Charles darwin’s “Tree of life” describes how species are related to other pertaining to evolutionary history.The conception is wrong according to scientists. Modern genetics have revealed by doing genetic tests on bacteria,plants and animals are mostly crossbreed than their original conception.i.e., the genes are passed on in and individual  branches of the tree of life,but they are transferred between species of various evolutionary tracts. The result is more complex and entangled.

Microbes exchange their genetic material  and it will be hard to distinguish one type from another. Likewise plants and animals are crossbreeds and  the resulting offspring are fertile.
