What evolutionary advantage does sexual reproduction grant *Lepidophyma* populations compared to purely clonal lines regarding long-term adaptation?
Answer
Maintaining genetic recombination for adaptation to shifting pressures
Sexual reproduction acts as a critical engine for long-term evolutionary success, especially when environments are unpredictable or subject to significant shifts. By involving genetic recombination, sexual populations continuously shuffle the genetic deck, creating novel combinations of genes. This mechanism allows these populations to potentially adapt more quickly to changing environmental pressures where new combinations of alleles might confer a fitness advantage. In contrast, asexual lineages rely solely on rare beneficial mutations arising within the clonal line.
