Natural Selection

Evolution occurs through natural selection, genetic drift, and adaptation. DNA mutations create variations in populations. Environmental pressures select advantageous traits for survival and reproduction.

Genetic Mechanisms

Genetic inheritance follows Mendelian principles and molecular genetics. Gene flow and genetic recombination increase diversity. Population genetics studies allele frequencies and evolutionary changes.

Species Development

Speciation occurs through geographic isolation and selective pressures. Adaptive radiation creates new species in diverse environments. Convergent evolution produces similar traits in unrelated species.

Research Applications

Evolutionary studies inform medicine, agriculture, and conservation. Understanding resistance evolution guides pest management. Phylogenetic analysis traces species relationships and disease origins. Shutdown123
