Hybrid speciation is a form of speciation where hybridization between two different species leads to a new species, reproductively isolated from the parent species. Previously, reproductive isolation between two species and their parents was thought to be particularly difficult to achieve, and thus hybrid species were thought to be very rare.
The domestic cat, African wild cat and European wildcat may be considered variant populations of the same species (Felis silvestris), making such crosses non-hybrids. Serengeti, a hybrid crossbreed of a Bengal and an Oriental Shorthair. Chausie, a hybrid between a jungle cat and domestic cat. Subfamily Pantherinae. Genus Panthera
The common frog is a poikilotherm and is able to function over a wide range of body core temperatures.. A poikilotherm (/ ˈ p ɔɪ k ə l ə ˌ θ ɜːr m, p ɔɪ ˈ k ɪ l ə ˌ θ ɜːr m /) is an animal (Greek poikilos – 'various', 'spotted', and therme – 'heat') whose internal temperature varies considerably.
A mule is a sterile hybrid of a male donkey and a female horse.Mules are smaller than horses but stronger than donkeys, making them useful as pack animals.. In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction.
[61] [62] Hybridization occurs where two species' range overlap to form hybrid zones; hybrids may be created by humans when animals are placed in zoos or due to environmental pressures such as predation. [61] Intergeneric hybridizations, hybrids of different genera, have also been found in the wild.
Pattern IA occurs in most turtles, with the transition between male-producing temperatures and female-producing temperatures occurring over a range of temperatures as little as 1–2°C. [15] Pattern IB also has a single transition zone, but females are produced below it and males above it. Pattern IB occurs in multiple fish species [5] and the ...
Sometimes, kleptothermy is not reciprocal and might be accurately described as heat-stealing. For example, some male Canadian red sided garter snakes engage in female mimicry in which they produce fake pheromones after emerging from hibernation. [11] This causes rival males to cover them in a mistaken attempt to mate, and so transfer heat to ...
A human–animal hybrid and animal–human hybrid is an organism that incorporates elements from both humans and non-human animals. Technically, in a human–animal hybrid, each cell has both human and non-human genetic material. It is in contrast to an individual where some cells are human and some are derived from a different organism, called ...
