name of the process - natural selection
how can it cause evolution?
organisms who are more adapted to their surroundings have a higher probability of survival. by having a higher probability of survival, they have a higher possibility of passing their genes, which are better adapted, to their offsprings. the weaker organisms are less likely to survive, and less likely to pass their genes on. over time, a species who has adapted better to their surroundings, will keep producing offspring’s with good “adapted” genes, eventually leading to change in species, as the less adapted organisms become less common due to lower survival rates.
