Bottleneck Effect: Bison 2

Storyboard Text

  • There were less than 100 wild-caught founders which means nearly all of us descended from them. It decreased the genetic diversity
  • Yes! I see you retained info from our lesson on alleles huh?
  • Oh, so that's why we all kinda look similar. I'm guessing it is because the frequency at which different alleles are found, changed, so there isn't many options we could look like.
  • I thought humans were smart? That they know genetic diversity is important. Like for evolution as beneficial adaptations can arise? Also, a lack of genetic variation makes us vulnerable to changing environmental conditions
  • I think some humans are trying to help but not enough
  • But they need us
  • Do they not care, at all?
  • I thought humans were smart? That they know genetic diversity is important. Like for evolution as beneficial adaptations can arise?
  • Yes we do. Let's try to stop future human bottleneck events.
  • The End
