Hmm very interesting, I was unaware of some of your example such as the Orangutan. Upon further research, at the Genus level "Two organisms from one genus might or might not produce an offspring with sexual fertility, but it is very certain that organisms from two different genera (plural of genus) can never produce a fertile offspring." While species has the same number of chromosomes and will produce fertile offspring. I guess my question, or perplexion, is why every verbally articulate human being on the earth now are solely the same species. Questions 1) Either by selection. 2) Even though genetic diversity. Maybe all our classifications are semantic, I'm still processing this. (Quote source: https://www.differencebetween.com/difference-between-genus-a...)
