New coyote-wolf hybrid sees explosion in numbers http://www.independent.co.uk/news/science/coywolf-new-coyote-wolf-hybrid-sees-explosion-in-numbers-a6717151.html
>In one of the great success stories of interspecies animal breeding, the coyote-wolf hybrid ‘coywolf’ can now count its numbers in the millions. >amazing contemporary evolution story that’s happening right underneath our nose >Some dispute whether the coywolf is genetically different enough to be considered its own species but Jonathan Way from the National Park Service says that there’s enough morphological and genetic divergence that it should be placed in a class of its own.
species as understood by geneticists, phylogenists, and most active biologists that understand evolution and speciation (creationism is a belief held by some doctors who are a type of biologist) and accept it
population that is closely related genetically and interbreeds regularly
closely related varies by species and size of population
a slow reproducing species like humans may be the same species for centuries and millennia of complete separation
bacteria can speciate in a few months under the right selective pressures ie an abundant but radically different food source which would take many new genes to be efficient at and a hybrid that digests two wildly different foods would reproduce too slowly
while a species like rabbits or squirrels that loses most offspring before they breed twice may speciate relatively quickly when separated geographically by obstacle or distance into different climates
"clines" Cline is a word used for a successful and populous species that has a large range compared to its movement and the territory of individual groups
depending on time since original expansion and interbreeding this can lead to complete separation and eventual speciation… or it could mean a stable population with gene flow never really separating- can't call the center populations hybrids because it started as one species that never broke contact
there are many ways speciation begins but not all of them are final - much to the torment of autistic evolutionists because if this example happened long ago there might be no genetic sign and often there won't be enough fossils to hint at it either
A species expands in numbers and begins speciation one way or another, climates shift and the distant relatives that can be distinctly identified start breeding again and form a hybrid - climate continues to become unfavorable to the parents and the hybrids and together with local extinctions or extirpations…
only one small and interbreeding population remains - possibly surviving and expanding again but as one homogenized species
TLDR interbreeding does not mean the same species pic related
