alt Hacker NewsIf you decide to redefine sex as a collection of traits, the problem with that is it's dependent on the specific developmental mechanisms of each species. Then the question is, how do you decide which traits are female and which are male? Especially in as yet undiscovered species. And how to classify species where each individual is both male and female?
The answer to all of this is to remember that sex is about reproduction, so it must fundamentally be based on gametes.
That's reproductive sex.
The question of classifying human births is larger - not all humans born have gametes. Some have two sets.
For people interested in actual observed birth cases there's a lot more going on than a moronically over simplified two buckets cover all cases when it comes to attributing sex [] .. clearly M or clearly F with everything aligned (physical form + chromosones + gamates) covers most cases .. and then there's the rest.
It gets even broader when including mammals such as rabbits and pigs as they express cases that are potentially possible in humans but not (as yet) observed or on record.

Wishful thinking stemming from a strong held preconceived idea of how the workd must be rather than field based observation of that which occurs.
