By the passage of time, from fin on lobe-finned fish changed to legs and feet on the early amphibians due to variations among offspring, followed by natural selection. These legs and feet containing amphibians lives both in water and land.
Genetic engineering because the genes of the plants were modified
D) each parent passes only one factor for each trait to its offspring
The structures that are in the body are In a complex environment, animals learn from their responses to stimuli and events. Appropriate response to reward and punishment can promote survival, reproduction and increase evolutionary fitness.
