But the male chromosome isn’t competing against the female chromosome. The mutant male chromosome is competing against the unmutant male chromosome. The mutant male chromosome is fitter, rises to fixation at its allele location, and in one more generation the species as a whole goes extinct.
I would still be loath to call it “evolved to death”. Where is the “evolution”? You are describing an event that would wipe out a species in an instant (considering it on the time scales that evolution acts on). Species die out instantaneously (on an evolutionary time scales) for many reasons.
How else can I respond to an event that takes “one more generation” to kill the whole species? Nothing “evolved”; the species died because the evolved machinery of genes didn’t preclude such a mutation from killing a species in a handful of generations. Too bad, so sad. If there was an “evolution fairy”, she would have designed a better machinery of genes. But if it is essential for the preferred use of the phrase “evolved to death” to describe events that take place instantaneously on an evolutionary time scale, I have to describe that phrase as misleading.
it is still possible for a species to evolve to extinction directly.
Favor me with another example. I found the other examples lacking.
From the fog of my misunderstanding, I am surprised you would use the phrase “evolved to death” without it immediately being followed by qualifications and clarifications. I look forward to you removing this fog away from my person.
