The Earth's freshwater is even rarer. For humanity to thrive, or even exist, we need to sprinkle that teeny bit of fresh water in the right places, at the right times and in just the right amounts, Gallo said. 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.

Mammals, and all other animals for that matter, are divided into classifications of species (taxonomic ranks). A species is defined as a group of organisms capable of breeding â¦ and producing fertile young. Therefore, it is possible to breed mammals of the same species together and produce fertile young. Some mammals of different species can be bred together but will produce infertile young; an example of this is the mule where a horse and donkey (different species) breed to produce an infertile mule as offspring. Answer#2: Only if they are related to one another.
