The Earth's freshwater is even rarer.

Here's how Earth's freshwater is spread around the globe: 1  70 percent of freshwater is locked in ice caps.
Believe it or not these are not the first lines of terrible jokes, but real scientific questions with real living answers. Hybrid animals are the offspring produced when two animals of closely related â but different â species breed.The young produced will usually not be fertile, and so hybrid species are not normally seen in the wild. In order for more of these hybrid animals to exist the original two species must be cross-bred again.elieve it or not these are not the first lines of terrible jokes, but real scientific questions with real living answers.

Wolf and wolf-dog hybrid ownership by private citizens has long been a contentious issue in the United States.Wolf-dog hybrid (hybrid for short) is a term used to describe an animal that is part wolf and part domestic dog. Dogs (Canis lupus familiaris) and wolves (Canis lupus) share an evolutionary past and thus share many physical and behavioral traits. Dogs evolved from wolves through a centuries-long process of domestication. Domestication is the process by which a wild animal adapts to living with humans by being selectively bred by humans over thousands of years.
