"octogintatetraploid" = 84-ploid (me 31 hours before my biology midterm)

Yeah, well, it's not an "error" in mitosis, but in meiosis, and it may not lead to speciation in case, for example, the 2n gamete fertilize a 1n, and 3n's are oftentimes sterile. Just saying, good vid.

Why is polyploidy almost always fatal in humans when there's complete tetraploidization events even in mammals as close to us as rodents?

Correct me if I am wrong. Any polyploidy in mammals, that includes rodents, has a reduce life span and generally sterile. This, in nature, prevents further genetic variation of said polyploidy mammal. (May be not entirely correct) Homeostasis in mammals are encoded within their genes and has acquired the necessary basic function. However, in polyploidy mammals, anything that adds or subtract has negative consequences in one way or another. Though, (again, theorizing), if it was helpful in anyway, nature will certainly find a way to pass on said genes. However, given the environmental factors currently on planet earth, changes that occur looks like snail pace in comparison to the time of the universe existent. Therefore, genes changes overtime to adapt to the factors it exist in. If anything that changes said factors, certain genes or polyploid in this case, may be selected as an adaptation. The billions of changes that occur each second/minute/hour/day etc. Polyploid is a normal occurrence in the span of 4.5 billion years of this planet. (Again, correct me if I’m wrong) This is my understanding anyhow
