Where Do Species Come From? (Speciation): Crash Course Biology #15

How can you tell two species apart? It’s not always simple. In this episode of Crash Course Biology, we’ll learn about speciation-a process that can happen over millions of years, or within a single generation. Along the way, we’ll discover how a single species can split into two and how a reptile from New Zealand continues to stump scientists.

    This is one of those “I didn't care, but now I have to know.” topics.

    Fun fact: many hybrids are named based on the Father/Mother combination of the species. If a Polar bear is the dad and a grizzly is the mom the hybrid is a Pizzley. Same logic is applied for Ligers, Tigons.

    A hebra is actually a thing. Zorse and Hebra are used interchangably based on which parent was male. It's important to differentiate because fundamental traits are often passed down by only the male or the female. This means that crossbreeds can have wildly different traits based on which parent was male, as foundational traits to their species don't get passed on.

    if a Tiger + Lion = Liger (or Tigon, depending on which is the male/female parent), Grizzly + Polar bear = Pizzly bear, Coyote + Wolf = Coywolf, Horse + Zebra = Zorse, Zebra + Donkey = Zonkey, why is Horse + Donkey = MULE and not Honkey?

    What makes plants so prone to polyploidy? Is it something about their structure that makes it happen more often, or is there something about the way of life in other kingdoms that makes polyploidy less successful among them? Is it as common among fungi as with plants?

    That was a bit oversimplified. and it did not really answer the questions I have about speciation.
