Definition of a human: has 22 + 1 sex chromosome from each parent for a total of 46 chromosomes. Derived from the Human
Genome Project's website. Notice how it states, "On December 1, researchers in the Human Genome Project announced the complete sequencing of the DNA making up human chromosome 22." So I've decided it's safe to make this assertion. I've also read other places that verify this.
Definition of a species: "A fundamental category of taxonomic classification, ranking below a genus or subgenus and consisting of related organisms capable of interbreeding."
These two combined would eliminate infertile/sterile beings (that are wrongly labelled as humans), Down's Syndrome, Turner's Syndrome, and other beings wrongly labelled as humans containing XXX, XXY, XYY and any other genetic modifications I'm missing. I've also heard that to be part of the same species one has to be able to produce VIABLE offspring (to eliminate grouping animals like donkeys, horses and mules together. This would further eliminate people who did not produce non-sterile offspring.
Maybe this is why you can see how the definition of human is flawed.
