Best Answer

Populations evolve mainly in two ways: By natural selection and genetic drift

Natural selection is the process by which forms of life having traits that better enable them to adapt to specific environmental pressures, as predators, changes in climate, or competition for food or mates, will tend to survive and reproduce in greater numbers than others of their kind, thus ensuring the perpetuation of those favorable traits in succeeding generations.

Genetic drift is random changes in the frequency of alleles in a gene pool, usually of small populations.

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 is meant by the statement Populations evolve individuals don't?

This statement refers to the fact that evolution occurs at the level of populations over generations, with changes in allele frequencies leading to evolution. It emphasizes that individual organisms do not evolve within their lifetimes, as they do not change genetically, but rather it is the population as a whole that evolves.

Do genera populations phyla kingdoms or individuals evolve?

Individuals evolve through natural selection, leading to changes in the characteristics of populations over time. These changes can eventually lead to the evolution of new species within a specific genus, which may contribute to the diversification of higher taxonomic groups such as phyla and kingdoms.
