Forms match habitats…but why? There must be some evolutionary force (selection) for different habitats…predation on the spiders, or maybe camouflage for their predatory activity (or maybe some other reason)

  1. Forms match habitats…but why? There must be some evolutionary force (selection) for different habitats…predation on the spiders, or maybe camouflage for their predatory activity (or maybe some other reason) But, the question for this paper is where did the “raw material come from” for selection to work on? Presumably there are these niches on all the islands, but where the organisms come from to fit into these niches?! Two possibilities that work singly or in combination… Colonization vs Speciation Twigs Moss Leaves Trunks

  2. What does this mean?

  3. What is this? What does this mean?

  4. What is this? What does this mean?

  5. Okay, so the evolutionary pattern matches the habitat differentiation! What does this mean?

  6. What does this mean?

  7. In this case, the evolutionary pattern is a not a match with the habitat…in fact , the phylogeny alone tells us nothing about the habitat selection… How is this different?
