In fact, the evolution of the majority of dog breeds is a relatively recent phenomenon, beginning with selective breeding practices during the past 200 years. Today, various breeds demonstrate a ...

Washington DC - Obesity is on the rise not just in humans but in dogs, whose history of selective breeding makes them an ...

A species is a group of organisms that interbreed to produce fertile offspring. Selective breeding is when organisms are deliberately bred so their offspring have the desirable characteristics.

A dog breeder explains selective breeding, looking at puppies that have useful and less useful traits. Michaela explains how artificial selection is also used in vegetables, showing how broccoli ...

A selective python breeder has created an Emoji Ball Python snake after 8 years of trying. Justin Kobylka breeds snakes with unique patterns and sells them. The patterns are caused by recessive ...

If significant changes like the ones found in this study took, say, 10 generations of selective breeding to be detected, it would take 30 to 40 years of work to see any effects. Coral reefs are ...

The "science" of eugenics proposed that human perfection could be developed through selective breeding. In the late nineteenth century researchers developed the idea, a blend of genetic research ...

From Pekingese to St. Bernard and greyhound, dogs come in such startling variety it's easy to forget they belong to the same species. The profusion of breeds today -- at least 150 -- reflects ...

Obesity is on the rise not just in humans but in dogs, whose history of selective breeding makes them an ideal species for ...

Researchers from MLU analyzed 3D scans of 135 pig skulls and found significant shape changes over just 100 years. Selective breeding and diet shifts led to shorter snouts and flatter skulls, even ...

Selective breeding is not considered a form of genetic engineering. Retinitis pigmentosa (RP) is the most common type of inherited retinal dystrophy without effective treatments. Here, authors ...
