Basically it is because they die and any mutations in germ lines, genetic recombinations and any beneficial variations die with them. Only populations evolve because the frequency of alleles in population gene pools change over time due to the selection of individuals who pass on these frequency changing traits to progeny.
A species evolves over time through the process of natural selection acting on individuals within a population. Individuals themselves do not evolve, as evolution refers to changes in the genetic composition of a population over generations.
It is not correct to say that individuals evolved because it is not possible for an individual to change drastically over their own timelife. Species have the faculty to evolve as a whole not as individual organisms.
The smallest biological unit that can evolve over time is an individual organism, typically a unicellular organism like bacteria or archaea. These organisms can undergo genetic mutations and natural selection, leading to the evolution of their populations over generations.
Populations evolve over time due to genetic variation, natural selection, and other mechanisms that drive changes in the gene pool of a population. Individual organisms do not evolve, but rather the population as a whole exhibits changes in its genetic makeup over generations.
Individuals cannot evolve in the biological sense because evolution occurs over generations through the process of natural selection acting on genetic variation within a population. An individual's traits may change during their lifetime due to environmental factors or personal choices, but these changes are not considered evolution.
a population adapts over time. an individual cannot adapt during its lifetime. it happens over many generations.
it cant evolve... if you evolved it from evee then.... yeah you cant evolve it

no he cant evolve
Evolution is defined as a change in allele frequencies over time. Since individuals have only the set of alleles that they're born with, an individual cannot evolve. This leaves the population as the smallest unit that can evolve.
Pelipper cant evolve.
it cant evolve
you CANT evolve mew !!!!
Its Simple it DOES not evolve it cant evolve!
abamasnow cant evolve
..... Tyranitar cant evolve!!
No you are stupid no you cant evolve a munarsha
