According to Neo-Darwinism, any species can come into being from its ancestor or ancestor. According to them, a species can exist only where its ancestors existed. But in many places biogeography rejects neo-Darwinism. You can understand from the following examples.
1. Giant tortoises are found on the Galapagos Islands, while the Galapagos Islands are located 600 kilometers offshore from mainland Ecuador in the Pacific Ocean. How did land turtles that can't swim get here?
2. Based on morphological and molecular analysis of platyrrhine monkeys from the South American continent, it is believed that their ancestors belonged to the continent of Africa. According to the fossil record, these monkeys appeared 30 million years ago, while according to the plate tectonic theory, the continent of South America separated from the continent of Africa 120 million years ago.
