Explain what is meant by the term evolution?

Answer 1

The term itself refers to the gradual shift of something over time.

More specifically, in Biology it refers to the gradual shift in traits in a population as caused by natural selection. Traits which are harmful or cause an organism to have a decreased chance to survive are 'selected against' in that they are less likely to pass on those traits. Likewise, traits which are beneficial cause there to be an increased chance the organism will survive to pass on it's traits.

Answer 2

The best definition of evolution would be the general definition of "A gradual process in which something changes into a different and usually more complex or better form". Mathematics and Biology also offer up their own definitions of evolution.

Answer 3

Evolution is the change in inherited characteristics in a population over successive generations.

The most widely accepted theory is evolution through natural selection. Natural selection is a gradual, non-random process causing changes in the frequency of certain biological traits in a population as a result of the reproductive success of those possessing these traits. This is commonly referred to as "survival of the fittest".

Answer 4

Evolution can be defined as a genetic change in a line of descent over time.

Survival of the fittest

Answer 5

The evolving of a species to fit into it's habitat.

Answer 6

Formal definition. Evolution is the change in allele frequency over time in a population of organisms.

Informally, it is just change over time.

Answer 7

Simply put, evolution is the change in allele frequency over time in a population of organisms. Simpler, change over time.
