He has master's and doctorate degrees from Cambridge in philosophy and history of science, and a bachelor's in physics, as well as having worked as a physicist for several years. He has also done extensive research on the issue and done lots of publishing on it. He's more qualified than almost any Hacker News poaster.
Every ounce of his scholarship has been firmly rejected by the scientific community at every step of his career. Any HN poster is perfectly qualified to assess his credentials and claims relative to those of the academic mainstream.
Edit to reply to comment below: Meyer himself agrees that it is in fact true, and would be the first to affirm that he has faced pretty stiff rejection by the scientific mainstream on questions of biology. One of his major talking points is his feeling that he's been ostracized from the scientific community. He would not agree with anyone claiming it's "not true" that he has clashed with modern scientific consensus.
