Differential reproduction is key in natural selection by impacting the success of passing on genes. Genetic variation from sexual reproduction aids in adaptation to environmental changes. Natural selection acts on an organism's phenotype, determining evolutionary paths.
Differential reproduction plays a crucial role in natural selection by influencing the success of organisms in passing on their genes to the next generation. Organisms that produce more reproductively successful offspring have a greater impact on subsequent generations, driving the process of natural selection.
For example, in sexual reproduction, the generation of genetically distinct organisms creates genetic variation, providing populations with the flexibility to adapt to changing environmental conditions, including the presence of rapidly reproducing pathogens.
Ultimately, natural selection acts on an organism's phenotype, which encompasses both individual and social traits that influence reproductive success, shaping the evolutionary pathways of populations over time.
