Answer:
The legs of the lizard
Step-by-step explanation:
Some Anolis species have different sizes of legs according to what part of the tree they inhabit and forage. An ancestral Anolis lizard species might have gave rise of different species nowadays. Anolis species that lives on twigs have shorter legs than the Anolis lizards that live on the trunk of a tree. This observation is explained by adaptive radiation, which lead to lizards with long and short legs to survive specially in the trunk and twigs, respectively. The lizards with long legs could survive and reproduce more than short legs lizards in the trunks of trees, therefore a population of long legs gained more individuals throughout generations and became more predominant on those areas.
