Question

Each organism in a population produces more offspring than can survive. This is called . In order for natural selection to occur, populations must have . When the environment changes, nature selects favorable . Over time, these in a population.

Answer 1

Each organism in a population produces more offspring than can survive, a process known as overproduction. For natural selection to occur, populations must exhibit genetic variation. When the environment changes, nature selects favorable traits. Over time, these advantageous traits become more prevalent in the population, a process called adaptive evolution.

Step-by-step explanation:

Natural selection is the process by which individuals with favorable traits are more likely to reproduce, leading to the prevalence of these traits in a population over time.

Individuals with traits that provide a reproductive advantage are more likely to pass those traits to their offspring. This means that not every individual will contribute equally to the gene pool of the next generation. This differential rate of reproduction is what drives the evolution of populations over time, potentially leading to the development of new species.

Answer 2

Step-by-step explanation:

Each organism in a population produces more offspring than can survive. This is called overproduction. In order for natural selection to occur, populations must have variation. When the environment changes, nature selects favorable adaptations. Over time, these build up in a population.
