In a new episode of Define the futureGeologist Casey Luskin discusses biogeography and the problems it poses for the idea of a global common descent. To make this work, evolutionists would have to propose, for example, that Old World monkeys roamed across the Atlantic from Africa to South America on a natural raft. really? This is some raft. How did the monkeys not starve to death? Or die of thirst? They couldn’t drink the salty ocean water, after all. And talk about the genetic bottleneck!
This is just one of several problems Luskin has raised with the idea that all species gradually evolved from a universal common ancestor. In his conversation with host Emily Reeves, he also touches on the issue of closeness, such as when two creatures are, at best, very distantly related, yet share a major common trait, such as humans and octopuses having camera eyes. But evolutionists concede that the supposed common ancestor of humans and octopuses didn’t even have eyes, which means evolutionists should hold to the view that this very specific marvel of optical engineering has evolved twice.
Luskin notes that this example of convergence is just one of countless such cases. In each case, evolutionists find ways to explain the problem further away, but Luskin compares that to this Patches on the rotations that Renaissance proponents of the geocentric solar system continued to introduce to explain the growing body of astronomical evidence conflicting with their geocentric theory. As your theory gets too messy and messy to explain the new data, maybe it’s time to step back from the theory and consider other possibilities. The alternative that Luskin prefers is the popular design.
