Hybridization is the crossing of species. It sometimes takes place in nature, such as when horses and donkeys mate to create mules (male offspring) or hinnies (female offspring), though oftentimes these hybrids are born sterile or struggle to find mates when they are old enough to breed. But advantageous hybridization has been observed in lots of species, such as in fruit flies in Hawaii and more recently in finches in the Galápagos.

Quotes
Half a millimeter can decide who lives and who dies. Since these slight variations are passed down from one generation to the next, the brood of a small beak and a medium beak would be likely to have intermediate beaks, equipment that would sometimes differ from their parents' not by one or two tenths of a millimeter but by whole millimeters, maybe by many millimeters. […] Daphne Major is not a forgiving place. A line of misfits should not last.
[…]
That is why the Grants are so puzzled now.

Quotes
The arrival of human beings means a new phase in the evolution of Darwin's finches, and its directions are still unclear. […] Rosemary and Peter do think they see something odd about the finches of Santa Cruz. The birds around the research station, and in the village, seem to be blurring together. The Grants have never made a systematic study of this: but to their eyes the species almost look as though they are fusing. "They just sort of run into each other," says Rosemary. There is no difference between the largest fortis and the smallest magnirostris.

You don't find situations that chaotic under natural conditions, but you do find them in the havoc that human beings bring in their train. […] Thus, our disturbances hybridize both the environment and the species.
We are hybridizing the planet.
