The island of Madagascar is located in the tropics 300 miles east of the coast of Africa, from which it separated 165 million years ago. It is characterized by a large number of endemic species. What are the main reasons that Madagascar is a hot spot of endemic biodiversity? a. Madagascar has a climate that is more conducive to evolution than the larger African continent. b. Madagascar is close to the tropics of Africa and consequently has a large number of species. c. Madagascar shows species diversity of both temperate and tropical regions. d. Madagascar has been isolated geographically and species evolved there without interaction with outside influences.

AFRICA MADAGASCAR lorises bushbabies lemurs W 254 mya 255 mya 262 mya This picture shows that the ancestor of modern lemurs left the African mainland and made it to the island of Madagascar around 54 million years ago. This ancestor then proceeded to evolve into all the different lemur species of today. This is an example of which evolutionary pattern? stabilizing selection stasis cladogenesis extinction
Each of the following observations comes from a different scientific discipline. Which is the best support for Darwin’s concept of descent with modification? a. Geologists provide evidence that earthquakes reshape life by causing mass extinctions. b. Botanists provide evidence that South American temperate plants have more in common with South American tropical plants than temperate plants from Europe. c. Zoologists provide evidence that fewer animal species live on islands than on nearby mainlands. d. Ecologists provide evidence that species diversity increases closer to the equator
