Growth & Evolution : Hybrids

GROWTH AND EVOLUTION : HYBRIDS

Hybrids are the offspring of two plants or animals of different species or varieties, a thing made by combining two different elements. Whilst hybrids can occur naturally, for the most part especially in modern times, its due to human interference, however direct or indirectly the interference is. Below is a list of hybrids found in more recent years...

Hybrid animals include;
MULES are mixes of male donkeys and female horses.

BEEFALOS are mixes of American bison and a cow.

URSID HYBRIDS occur between black bears, polar bears and brown bears. (The above picture is of a Grizzly/Polar bear hybrid)

LIGERS are mixes of a male lion and a female tiger, and a TION is a female lion mixed with a male tiger.

CANID HYBRIDS occur between cyotes, wolves, dingoes, jackals and domesticated dogs.

WHOLPHINS  are mixes of false killer whales and bottlenose dolphins, they are very rare.

A CAMA is a mix of a camel and a llama.

  • Ligers are the results of breeding a male lion with a female tiger (and a Tion is the reverse). This is a completely human induced process, due to lions and tigers naturally living in habitats thousands of miles away from each other so it would be physically impossible for them to naturally breed without human interference. The offspring usually suffer from birth defects and may die young.

  • A Grolar bear is a Grizzly bear and a Polar bear hybrid, of very rare occurence due to (although sharing the same countries) the fact polar and grizzly bears tend to avoid each other. Theories for the cause of this naturally occurring hybrid may be that polar bears are being driven southward by the melting of their ice cap habitats, bringing them into closer contact with the grizzlies.
