Detailed explanation-1: -Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes.

Detailed explanation-2: -Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.

Detailed explanation-3: -Microevolution and Macroevolution. One can distinguish between two general classes of evolutionary change: microevolution (change below the level of the species) and macroevolution (change above the level of the species).

Detailed explanation-4: -A genetic mutation is a change to a gene’s DNA sequence to produce something different. It creates a permanent change to that gene’s DNA sequence.

Detailed explanation-5: -A population is a group of individuals that can all interbreed, often distinguished as a species. Because these individuals can share genes and pass on combinations of genes to the next generation, the collection of these genes is called a gene pool.
