What is adaptive evolution How could evolution possibly be n

What is adaptive evolution? How could evolution possibly be non-adaptive or even maladaptive? If you think about the forces that can change allele frequencies, which could result in each?

Solution

Adaptive evolution is produced by natural selection. Adaptive evolution define why different species live in their particular environments.
It also defines cross purposes of some species to others.

Evolution possibly be non-adaptive or even maladaptive because their effects are independent of adaptive significance and organisms traits are well adapted . It may also be caused when there is lack of genotypic variation and it respond to selection.

Forces that can change Allele Frequencies:
1. Mutation – introduces new alleles into
population
2. Natural Selection – specific alleles are
much more likely to be exceeded.
3. Non-random Mating – individuals of 1
genotype are more likely to mate with
individuals of equal genotype
4. Migration – individuals with unique
genotypes circulate in or out of a populace
5. Genetic Drift – random changes in allele
frequencies.
