Both of them (tortoises and anoles) represent examples of evolution observed by different scientist.
Darwin proposed that animals such as Galapagos tortoises changed as they adapted to new environments and this observation led to his theory of evolution by natural selection.
On the other hand, Losos observations were anoles of the Caribbean islands. He noticed that physical characteristics of those animals changed in response to their environment change. The traits that changed were the ones that affect the survival of anoles. Losos also concluded that the similar lizards that are not closely related, but were similar evolved separately in response to their environment. This is known as convergent evolution.
