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

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.

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.

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?

Well done!!! Excellent way to sneak up some serious science in this 101-style course ☀️

Hi, Friendly Neighborhood Entomologist! I'm the Friendly Neighborhood Anthropologist. In undergrad, we really emphasized the Phylogenetic Species Concept (operational) and the Evolutionary Species Concept (theoretical). My prof told us to ignore the Biological Species Concept haha (for the purpose of the classes)

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?

Hey. I just finished hank's crash course on biology. You think you can hang with the man who coined "biolography"? We shall see.

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