Question

Through which mechanism does evolutionary change occur at the population level?

विकल्प

• Individuals altering their inherited genes during their lifetimes

• Direct transmission of acquired behaviours to offspring

• Shifting gene frequencies within the population over time

• Simultaneous identical mutation of every individual

Answer 1

Evolutionary change occurs exclusively at the population level through shifting gene frequencies over time. Individual organisms cannot evolve because they are fixed with their inherited genes.
