The real problem with divisions of species isn't that they are just guidelines, but that nobody can agree on the rules. Evolutionary biologists have proposed almost 30 different species definitions (called "species concepts") over the years, and none of them apply to all organisms. For example, the "no fertile offspring" definition is a paraphrase of one of the most popular species concepts called the Biological Species Concept (BSC), which actually states that a species is "a population or group of populations reproductively isolated from other such groups". "Reproductively isolated" in this case can mean "no fertile offspring", but it can also mean "they never encounter each other" or "they don't see each other as potential mates". The problems with the BSC are: 1. it doesn't work for organisms that reproduce asexually, 2. lots of organisms we would otherwise call different species have hybrids from time to time, and 3. reproductive isolation is actually really difficult to test (many organisms will hybridize in captivity but almost never in nature). As I said, there's like 30 more definitions of species that have been proposed, and most of them are slight modifications of other species concepts to fix problems with them (and introducing new problems lol). Some researchers have tried to come up with a definition that unifies all these different definitions (e.g. "a species is an independently-evolving metapopulation lineage"), but unified definitions fall apart because they're almost impossible to apply in the real world (how do you determine if something is "independently-evolving" or part of a metapopulation?).

>>947069914It's not just the definition of the term species that is far from clear cut. For example, even though we humans have spent much of our existence dividing individuals who look different up into what we seemed to think were distinct "races", it's actually ways off from the true scientific definition of the term. Biologically, with the amount of commonality in our genes that we share, every single one of us whether your ethnic roots are at the North Pole or in central Europe or Oceania, we're actually much closer to the definition of "breed", as in, dog breeds. But even at that, there is much more genetic diversity between most different dog breeds than there is between a person with ethnic roots in Scandinavia and somebody originally from South America. Compared to the rest of the animal kingdom, humans are almost unusally genetically similar, considering that ethnic appearance in humans can still vary to a considerable extent. Which is still a consequence of a near-extinction event that befell Homo Sapien very early on in our history, just after the dawn of our species and before we had even begun to disperse across the globe, and where it's thought that fewer than 50,000 individuals survived. In that sense, we're all descendants of the few that made it past that bottleneck.The take-home from this should be that, although we may sometimes look different from each other, we are genetically so similar that both racism and any other notion that one ethnicity of us is superior or inferior to another is the biggest and most harrowing bullshit that humanity has ever come up with since literally the first anatomically modern humans walked the Earth. And it makes all the things that humans do to each other because of that idea of racial or ethnic superiority all the more harrowing.
