Based on Darwin’s ideas of descent which modification and natural selection which observation would best support the idea that increased competition causes changes in species

Answer 1

One observation that would best support the idea that increased competition causes changes in species is the phenomenon of adaptive radiation. Adaptive radiation occurs when a single ancestral species rapidly diversifies into multiple new species, each adapted to a specific niche or environment. This is often precipitated by a new competitive pressure, such as the introduction of a new predator or the migration of a competing species into the same habitat. The increased competition for resources drives the organisms to evolve and adapt in order to survive and reproduce, leading to the formation of new species. This process is a clear example of how competition can drive significant evolutionary change within a species.
