Are Men Doomed To Go Extinct?

The Sydney Morning Herald on evolutionary scientists’ assertion that biological males as we know them are on the way out, due to the inherent flawed nature of the Y chromosome:

The poorly designed Y chromosome that makes men is degrading rapidly and will disappear, even if humans are still around.

Evolutionary geneticist Jenny Graves says that while the process is likely to happen within the next five million years, it could have begun in some isolated groups. Professor Groves, who first made the prediction some years ago, gave a public lecture on the subject for the Australian Academy of Science.

If humans don’t become extinct, new sex-determining genes and chromosomes will evolve, maybe leading to the evolution of new hominid species. “As long as something came along in its stead, we would not even suspect without checking the chromosomes,” she said on Tuesday. This had happened in the Japanese spiny rat, which had survived the loss of its Y.

    Monsanto will have made everyone sterile long before that with their healthy GMO crops.

    I guess I am going to have to start taking Testosterone Replacement therapy once I become immortal because my balls might fall off in 5 million years.

    Somewhere there is a group of feminazi geneticists modifying Wolbachia to infest humans.

    there is abundant archeological evidence that
    there have been hundreds of different humanoid species on Earth in the past 4 billion years
    some of whom we are related to & some not
    as to this version called Homo sapiens
    I think Homo says it all

    It’s a bit meaningless when you have prove a point by referring to 5 million years in the future. All species will become extinct at a certain point in time.

      Yeah, anticipating an evolutionary trajectory 5 million years out seems absurd when no one really understands the system we’re all living in to begin with.

        You didn’t understand the article because you have a low IQ.
