Good To Know: Human's Earliest Known Ancestor Had A Mouth But Lacked Anus

January 31, 2017


Seen here looking eerily like several of my relatives, an artist's rendition of Saccorhytus smiles for the camera. Saccorhytus, which were about one millimeter long, lived some 540-million years ago and are believed to be the earliest known ancestor to humans and a bunch of other species. Interestingly, Saccorhytus had a mouth but no anus, meaning the mouth was used for both consuming food and expelling waste. That's nasty. We sure have come a long way, haven't we? 540-million years ago we didn't have one at all, and now it seems like a lot of people are almost entirely anus. Oh, evolution.

Thanks to Mark B, who's convinced 540-million years from now we won't have mouths or anuses.

    No anus? Sex must have been terrible.

    So you're saying Saccorhytus doesn't give a s**t?

    Funny - our current POTUS is all mouth AND anus.

  • Sounds like it's literally full of shit.

  • Jenness

    I admit there is this part of me that thinks some scientists just make shit up and they are so good at it that it just kind of gets a "whatever, sounds legit" and then we just go with it because it would take too much effort to disprove

  • No, that's religion you're thinking of.

    Saccorhytus' have been making excuses for their bulimia for 540 Million years. This 'no anus' b.s. is just the most recent nonsense being spread by alternative news sources. Don't buy the hype, Saccorhytus have a disorder and need treatment, see the signs, get them help, and save what could potentially be a human life in roughly 540-Million years.

    If you see something, say something.
