Sure okay some tarantulas developed a dwarfism trait and some developed a trait in their DNA that allowed them to grow abnormally large. But how did these species survive? What factor (maybe like environment space or something) allowed them survive instead of just dying off?
Example, lets just talk about Darwin's findings on the Galapagos islands. Some finches developed a mutation where they got a different shaped beak. This benefited them because a thinner beak allowed some finches to feed from pollen and such, and the bigger, wider, stronger beaks allowed some finches to crush nuts.
But why was a dwarf tarantula, or a large tarantula, beneficial? How did these species thrive?
I hope you understand what I'm asking.
I'm doing an essay, actually. This is why I'm asking. What better example to use than tarantulas? Or maybe tarantulas aren't a good example... I'm just trying to compare how two towns in a book (The Chrysalids in case you're wondering) resembles evolution.
If you can, can you perhaps recommend me to someone who might know, or a website, or something? I need a secondary source to back up my points.
BUT YEAH. Why or how did these tarantulas survive?
My theory is that bigger tarantulas -> scarce food, largeness allows them to easily take down larger prey like rodents rather than just insects. Possibly also because they had to travel at a greater distance to find food or etc. Smaller ones -> smaller prey. Able to catch and eat smaller prey. Also able to fit into smaller areas.
Also H gigas can swim... maybe because their species was more towards a lake or ocean, and in that period of time there was little land-food, so they went to go and fish?
Damn I'd love to study the genetic code of tarantulas...
Thanks for any help.
