Approximately 22 million years ago, the first fossils of gemsnakes began to appear on the island. Now, there are 109 known species of gemsnakes im Madagascar.

Select all that apply. dispersal into different habitats: large-scale (desert, forest, grassland, etc.) and small-scale (underground, on the ground, up ina tree, etc.) ( changes in mating behaviors and/or assortative mating specialization on different types of prey (rodents, bird eggs, other snakes, etc.) Part 2 Which evolutionary mechanism is the biggest driver of rapid speciation when new ecological opportunity is the trigger? mutation genetic drift natural selection
