Biographical observations suggest that a modification process caused new species to arise in the way that new species are showing up without explanation and with new adaptations to their environment. One example that is widely used is the appearance of opposable thumbs in humans and monkeys.
Biogeographic observations indeed suggest that a evolutionary process caused new species to arise, through the process we call natural selection. This is due to an animals adaptability in it's environment.
Darwin used the phrase "descent with modification" in his book "On the Origin of Species" instead of the word "evolution." He used this phrase to describe the process by which species change over time through natural selection.
Organisms on island clusters were very similar to each other and to nearby mainland species.
That the offspring of one species may adapt to it's surroundings and live longer then though without the modification.
Darwin's theory of descent with modification, also known as evolution by natural selection, proposes that species evolve over time through the process of variation and differential survival and reproduction. This means that species descend from common ancestors and accumulate changes or modifications that help them adapt to their environment.
Charles Darwin's idea of how species change over time is called natural selection. This process involves the survival and reproduction of organisms that are best adapted to their environment, leading to gradual changes in the characteristics of a population.
