Darwin' theory is that life changed or evolved through a process called natural selection. The theory is sometimes described as "survival of the fittest," but that can be misleading, Pobiner said. Here, "fitness" refers not to an organism's strength or athletic ability, but rather the ability to survive and reproduce.
Darwin also described a form of natural selection that depends on an organism's success at attracting a mate, a process known as sexual selection.
The colorful plumage of peacocks and the antlers of male deer are both examples of traits that evolved under this type of selection.
Darwin didn't know anything about genetics, Pobiner said. "He observed the pattern of evolution, but he didn’t really know about the mechanism."
That came later, with the discovery of how genes encode different biological or behavioral traits, and how genes are passed down from parents to offspring.
The incorporation of genetics and Darwin's theory is known as "modern evolutionary synthesis."
Darwin's book "On the Origin of Species" proposed the process of natural selection as the mechanism for evolution. This theory suggests that organisms with traits best suited to their environment are more likely to survive and reproduce, passing on those favorable traits to their offspring. Over time, this process leads to changes in the characteristics of a population, which can result in the evolution of new species.
Darwin's book "On the Origin of Species" suggested that organisms evolve through the process of natural selection. This process involves the competition for limited resources, with individuals possessing advantageous traits being more likely to survive and reproduce, passing those traits on to their offspring. Over time, this leads to the gradual change and adaptation of species to their environment.
Darwin's book, "On the Origin of Species," suggested that organisms evolve through natural selection. This process involves organisms with favorable traits being more likely to survive and reproduce, passing those traits on to their offspring. Over time, this results in the adaptation and change of populations to better suit their environment.
Comparing organisms can show similarities in their DNA, anatomical structures, and developmental processes. These similarities suggest that the organisms share a common ancestor and have evolved from it through the process of descent with modification. By studying these similarities, scientists can trace the evolutionary history of different species and understand how they are related through common ancestry.
Darwin's Theory of Evolution states that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce within their environment. Over time, this process leads to the gradual change and divergence of species.

Most organisms develop through a process that starts with the fertilization of an egg
through a process called photosynthesis.

These three ideas seem to run together, so it's important that you are able to distinguish among them. The theory that organisms change over time is evolution. The mechanism by which organisms evolve is natural selection. Survival of the fittest explains how natural selection works.Answer = Natural SelectionThe process of natural selection, of course.
