Final answer:
The evidence in the change in teeth of fossil antelope from browsing animal to grazing animal provides evidence for the adaptation of teeth to a new diet.
Step-by-step explanation:
The evidence in the change in teeth of fossil antelope from browsing animal to grazing animal provides evidence for the adaptation of teeth to a new diet. As antelopes transitioned from browsing on leaves and soft vegetation to grazing on tough grasses and grass seeds, their teeth evolved to become longer and covered with cement, allowing them to grind and chew tough plant material without wearing out their teeth. This adaptation in teeth structure provided them with the ability to efficiently consume grasses and survive in grassland habitats.
