    Reading 1998 report on section exc at Grotte du Renne, they found at base of Chatelperronian a limestone plaque with black and red pigment on it. Anyone know if this has been analysed with modern methods?

    I generally refuse to believe things are real until a plane ticket materializes. Yesterday I received a one-way ticket to Indonesia to begin a year of research—after months of waiting! A 📸 of the volcanos that loom over the town of Ruteng, near that hobbit cave, to celebrate!

    The discussion continues, there are no valid arguments against rock art of . Skeptics are cordially invited to come to . The cave can be visited by appointment. New datings are in progress

    There’s also the cost to the planet. Reading the IPCC report now and it’s so frustrating that scientists call for action on climate change yet we can’t come up with better ways to network than to fly places.

    a question I have been asking myself a lot recently: why did post-neolithic civilizations around the world reject cannibalism as part of death/funeral rituals, after embracing it for maybe millennia?

    Way to go !

    We are so proud of our own Dr Julie Lesnik, who was one of four faculty at Wayne State to receive the Prestigious Junior Faculty Research Award from the WSU Academy of Scholars tonight! Way to go!

    In summary, toes are cooler (& more fascinating) than I realized! I plan to keep my mine for now :) Toe joint dynamics (esp. stiffness) have a larger effect on gait mechanics than I expected. We r excited to continue this line of research. Stay tuned! 9/9

    I've spent most of my research career studying ankles, knees & hips. But we recently took a detour to examine the role of toe joint dynamics. Our first study has yielded some interesting and also unexpected results thus far... 1/n

    For folks at the conference in San Diego next week, I'll be hanging out in the Inspiration Lounge on Thursday 10/18, starting at 12:30. Come stump me on human origins!

    Holocene migrations happened, but possibly natural selection accelerated some demographic changes, or filtered some alleles from spreading. At an extreme, ignoring selection might make "ghost populations" appear in models.

    Replying to @johnhawks @eLife @Kelley__Harris
    "It remains to be seen how much of what we think we know about human history has been thrown off by non-neutral evolutionary forces." Potentially radical overturning of 'settled' migration paradigms?

    Have to give a presentation next week that requires Powerpoint be uploaded in advance. Haven't used PP in 15 years. Seriously considering making timed video of Prezi to embed in PP.

    Um, what? “Because Crispr involves only the removal of DNA, not the addition of new material, the resulting produce isn’t considered genetically modified organisms in the U.S. or Canada, Dr. Van Eck said.”

    Endorse. I submit papers with words spelled out and often editors insist that I take out the words and use abbreviations in their place. We don't need the cognitive load that abbreviations impose.

    I feel strongly there needs to be an editorial ban on using excessive abbreviations - it makes reading articles near impossible when you have to spend time flipping back and forth for definitions and I've almost given up on a good article in despair and fury.

    Of course, the mechanisms of background selection and draft were formulated before genome-wide data were available. But most people still assumed the genome was 98% neutral.

    I think of how hard we had to fight fifteen years ago to get people to acknowledge that selection had an important effect on genome-wide variation.

    Great insight article by : "Just 5% of the human genome is subject to neutral evolution, but this process remains central to understanding the history of human migration across the Earth."
