What are examples of are selected species?
r-K selection: the development-reproduction trade-off. Typical examples of r-species are mice, rabbits, weeds and bacteria, which have a lot of offspring, but a short life expectancy. Examples of organisms undergoing K selection are tortoises, elephants, people, and sequoia trees: their offspring are few but long-lived.
What are the different classifications of animals?
The classification system is based upon Latin names . The scientific classification of human beings, from kingdom to species, follows: animalia, chordata, vertebrata, mammalia primata, hominidae and then “homo sapiens.”.

How are species commonly defined?
A species is commonly defined as a population of organisms that can interbreed and reproduce under natural conditions. This definition has limitations, though, and is less useful for asexual microorganisms that exchange genes freely. Even those species that can reproduce with other species typically do not do so under natural conditions.
