Footprints

Matt Mullenix sends news of some possible pre- Clovis footprints preserved in volcanic rock in Mexico. Most authorities are skeptical, but express openness to seeing the new evidence. Pre- Clovis Americans, if they existed, seem to have left little BUT footprints so far. Maybe Matt has the answer: "Hmmmmm. makes you wonder if the first large mammal species slaughtered into extinction by human immigrants from Asia was.....an earlier human immigrant from Asia".
