Microevolution is the change in allele frequencies that occurs over time within a population this change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic driftthis change happens over a relatively short (in evolutionary terms) amount of time compared to the changes termed 'macroevolution' which is where greater differences in the.

In general you should describe each of the four forces of evolution, to a degree that lets me know that you understand each of them you should also cover both the concept of species and population given that variation is also critical to the process, a description of variation between populations is also necessary. These four forces continue to be valid when moving to a phenotypic view of evolution in particular they are actually the only four logical ways that we can have the addition or loss of individuals from a population in a constant environment.
The evolution of humans is the concept that humans evolved from the same ancestors as apes and monkeys human evolution is the part of biological evolution concerning the eme rgence of humans. Microevolution (evolution on a small-scale) refers to the changes in allele frequencies within a single populationallele frequencies in a population may change due to four fundamental forces of evolution: natural selection, genetic drift, mutations and gene flowmutations are the ultimate source of new alleles in a gene pool.

Forces that drive evolution categorizing the processes that affect allele frequencies might be subject to issues of semantics without going into the details, we generally recognize 4 forces that drives evolution. Macroevolution is evolution on a scale at or above the level of species, in contrast with microevolution, which refers to smaller evolutionary changes of allele frequencies within a species or population.

4 forces of evolution can anyone tell me about the 4 forces of evolution also, could you give me some ideas as to how cultural activities, beliefs and values influence them. In this view, four evolutionary forces (mutation, random genetic drift, natural selection, and gene flow) acting within and among populations cause micro-evolutionary change and these processes are sufficient to account for macro-evolutionary patterns, which arise in the longer term from the collective action of these forces.
