“Genesis” and the idea that someone could have evolved from an arachnid
“Genesis” is a seventh season episode that takes on the science of evolution, by proposing that humanoids could share genes with a whole myriad of creatures, including spiders. While the idea is ridiculous on its own, it’s also in complete conflict with “The Chase,” a season six gem in which it’s discovered that all of the humanoid species in the galaxy were created by a single alien race who just wanted to spread their seed. Goddammit, could no one in the writers’ room have taken a freshman biology course?
