The Genera Theory

**The Genera Theory** is a scientific theory that suggests than subspecies and species under the same genus are able to be attracted, mate and successfully crossbreed.

## About

The subject of hybridization amongst organisms has been very controversial amongst the science community, with different experts having different approaches. But this one may be the one that will solve everything. The Genera Theory suggests that subspecies or species of animals within the same genus are able to be attracted, mate and successfully crossbreed.

## Ways to be prove it

The genera theory can be proven in three ways:

-Most prehistoric animals are referred by the name of their genera but not by the name of a species.

-All species within the same genera generally look very similar and their scientific names start with the same word.

-The vast majority of hybridization examples in the wild have happened between species or subspecies within the same genus

## Notable examples

This are examples of hybridization in the wild:

-Homo Sapiens Sapiens x Homo Neanderthaliensis

-Homo Sapiens Sapiens x Homo Denisova

-Homo Sapiens Sapiens x an unknown Homo species

-Homo Sapiens Sapiens x an unknown Homo species

-Canis Lupus x Canis Latrans

-Leopardus geoffroyi x Leopardus tigrinus

-Panthera Leo x Panthera Uncia

-Mammuthus primigenius x a lineage related to Mammuthus trogontherii

-Corvus cornix x Corvus Corone

-Mus musculus musculus x Mus musculus domesticus

-Setophaga occidentalis x Setophaga townsendi

-Setophaga coronata auduboni x Setophaga coronata coronata

-Vermivora chrysoptera x Vermivora cyanoptera

-Carcharhinus limbatus x Carcharhinus tilstoni

-Salvator rufescens x Salvator merianae

-Ursus Maritimus x Ursus Arctos

-Crocodylus rhombifer x Crocodylus acutus

-Chrysolophus amherstiae x Chrysolophus pictus

-Mauremys reevesii x Mauremys mutica

-Mauremys annamensis x Mauremys sinensis

-Alouatta palliata x Alouatta pigra

-Felis silvestris x Felis catus

-Macropus fuliginosus x Macropus giganteus

-Salvelinus Fontinalis x Salvelinus namaycush

-Oncorynchus Mykiss x Oncorynchus Clarkii

-Zea diploperennis x Zea perennis

-Zea perennis x Zea mays

-Musa acuminata x Musa balbisiana

## What is this theory trying to prove?

The theory tries to prove many things. For centuries, species was once though to be the main taxonomic category. But this theory suggests that genus should be the main taxonomic category while species are multiple variants of it. Many people have thought that hybrid animals are genetically deformed or do not work. This theory however, suggests that only inter-genus hybrids are the one's who are genetically deformed or polluted. And that hybrid animals of the same genus have mixed genes rather that polluted ones.
