Populations evolve as changes in genes are passed down from parent to offspring. When a genetic change is passed down, it is there with the offspring organism from the start of its life and can affect how it develops. The organism with the altered genes can then pass those changes down to its own offspring, and thus the change can affect a population over the course of generations. So evolution occurs not by individuals changing, but from each new generation being slightly different from the previous one.
An individual organism keeps the same set of genes it is born with through its entire life.

Did you evolve?
Populations evolve, individuals are selected.
What is meant by the statement Populations evolve individuals don't?
Only genetic changes in populations can indicate that evolution is taking place.
Can populations evolve?
Evolution is the change in allele frequency over time in a population of organisms.Short answer, populations are the only thing that evolves. Individuals die. Traits are passed on to progeny that make up the variations in the populations that evolve.
Do genera populations phyla kingdoms or individuals evolve?
which of the following evolve? population, genera, kingdoms, phyla, or individuals
Which does natural selection affect populations or individuals?
Populations evolve, but individuals are selected. Natural selection affects individual organisms.
What is the only thing that natural selection can act on?
The phenotype or genome of the individual organism. Remember, individuals are selected, populations evolve.
The smallest unit of evolution is the population?
Yes, populations evolve. Individuals/genes are selected.
What did you evolve from?
I did not evolve from anything! Individuals are naturally selected and populations evolve. Understanding this simple fact can explain certain things that creationists do not seem to understand. Such questions as, " where did the first man find the first woman? " When you understand that populations evolve and individuals are selected then you will see that questions as the one you asked and questions as the one I used as an example are just silly.
What characteristic defined individuals that survive according to Darwin's theory?
That are reproductively successful. The individual dies; populations evolve. Individuals are naturally selected.
Does the population or organism go through natural selection?
No, populations of organisms evolve, individuals are naturally selected.
Why do gene pools lie at the root of evolution?
Basically because only populations ( populations gene pools ) evolve. Individuals die and any variant trait in their germ line must be passed into the gene pool. This way, in time, this trait may spread and the population evolves.
What is the importance of reproduction in natural selection?
Everything! Survival is the race, but reproductive success is the finish line. Remember; individuals die, populations evolve.
