Your statement is false, even for humans. See for example: Gender change in 46,XY persons with 5alpha-reductase-2 deficiency and 17beta-hydroxysteroid dehydrogenase-3 deficiency (full text here). People with this condition literally undergo physiological changes in biological sex at puberty, to varying degrees. As I said earlier, conditions like this are relatively rare (although it can become more common in certain sub-populations, cf. the above article p. 400), but your claim that "one absolutely cannot become the other" is false, as is the claim that sex is strictly dimorphic, which I covered earlier.
To repeat myself, human sex is nearly dichotomous, and that clearly does matter to an understanding of social norms about gender, but it's not the same as being absolutely dichotomous, and the failures involved with treating sex as an absolute binary are important to understanding the existence of transgender people.
Defects and aberrations are just that; nothing more nor less.
