Therefore, the question about the origin of Strepsirrhini monkeys is incorrect. Instead, we can ask: Where did the Strepsirrhini come from?
The answer is: Africa and Asia.
* Lemurs are endemic to Madagascar, meaning they evolved and diversified exclusively on this island.
* Lorises are found in parts of South and Southeast Asia, including India, Sri Lanka, and parts of mainland Southeast Asia.
* Galagos (also known as bushbabies) are found in mainland Africa, primarily in sub-Saharan regions.
It is believed that the Strepsirrhini lineage diverged from other primates about 58 to 63 million years ago. Fossil evidence suggests that they originated in Africa, and some members of the group later spread to Asia. The lemurs of Madagascar are thought to have arrived there around 60 million years ago, likely by rafting across the Mozambique Channel.
In summary:
* Strepsirrhini are not monkeys.
* They are a distinct infraorder of primates that include lemurs, lorises, and galagos.
* Their origins are in Africa, with lemurs later colonizing Madagascar.
* Lorises are found in parts of South and Southeast Asia.
