Example: Tarsiers vs, Lemurs

- Early primates faced intense competition from other small mammals, such as lemurs and rodents , for similar niches and resources

- In response, some primates took evolutionary pathways that distinguished them from their competitors.

- Primates began exploring arboreal habitats as a way to access new sources of food and escape the intense competition on the ground

- This shift was driven by necessity as other arboreal mammals, including lemurs, were already exploiting treetop niches.

- Consequently, primates specialized in navigating complex, high-canopy environment. they developed strong gripping abilities through the growth of elongated fingers equipped with enlarged fingertips with nails rather than claw. The nails gave primate the ability to hold on to tree branches more adeptly compared to animals with claws.

By embracing and excelling in the arboreal lifestyle primates gradually gained the competitive edge on various animals which paved the way for their subsequent radiation and evolutionary success. Thus highlighting how a driving pressure in the competition between species had a profound influence on our evolutionary path
