Evolution and the Human Body

Signs of evolution can easily be found in the human body. Vox recently put together this AMAZING video explaining how you can see evidence of evolution in your own body. From babies born with tails to why you get goosebumps.

I can’t recommend this enough to get a better understanding of how evolution has affected the human body.

Microbes and You

(Note: The following is a news release from the University of Oklahoma)

Norman, Okla.—University of Oklahoma anthropologists are studying the ancient and modern human microbiome and the role it plays in human health and disease.  By applying genomic and proteomic sequencing technologies to ancient human microbiomes, such as coprolites and dental calculus, as well as to contemporary microbiomes in traditional and industrialized societies, OU researchers are advancing the understanding of the evolutionary history of our microbial self and its impact on human health today.

Christina Warinner, professor in the Department of Anthropology, OU College of Arts and Sciences, will present, “The Evolution and Ecology of Our Microbial Self,” during the American Association for the Advancement of Science panel on Evolutionary Biology Impacts on Medicine and Public Health, at 1:30 pm, Sunday, Feb. 14, in the Marriott Marshall Ballroom West, Washington, DC.  Warinner will discuss how major events, such as the invention of agriculture and the advent of industrialization, have affected the human microbiome.

“We don’t have a complete picture of the microbiome,” Warinner said. “OU research indicates human behavior over the past 2000 years has impacted the gut microbiome.  Microbial communities have become disturbed, but before we can improve our health, we have to understand our ancestral microbiome.  We cannot make targeted or informed interventions until we know that.  Ancient samples allow us to directly measure changes in the human microbiome at specific times and places in the past.”

Warinner and colleague, Cecil M. Lewis, Jr., co-direct OU’s Laboratories of Molecular Anthropology and Microbiome Research and the research focused on reconstructing the ancestral human oral and gut microbiome, addressing questions concerning how the relationship between humans and microbes has changed through time and how our microbiomes influence health and disease in diverse populations, both today and in the past.  Warinner and Lewis are leaders in the field of paleogenomics, and the OU laboratories house the largest ancient DNA laboratory in the United States.

Warinner is pioneering the study of ancient human microbiomes, and in 2014 she published the first detailed metagenomics and metaproteomic characterization of the ancient oral microbiome in the journal Nature Genetics.  In 2015, she published a study on the identification of milk proteins in ancient dental calculus and the reconstruction of prehistoric European dairying practices.  In the same year, she was part of an international team that published the first South American hunter-gatherer gut microbiome and identified Treponema as a key missing ancestral microbe in industrialized societies.

Warinner has published 17 peer-reviewed journal articles, 2 books, and 5 book chapters, and she serves on the Editorial Board of Scientific Reports.  Her research earned an Honorable Mention for the Omenn Prize, an annual prize for best article published on evolution, medicine and public health; and her ancient microbiome findings were named among the top 100 scientific discoveries of 2014 by Discover Magazine.

Warinner’s research has been featured in more than 75 news articles, including stories in Science, Cell, Scientific American, The New Scientist, Archaeology Magazine, the LA Times, the Guardian, WIRED UK, MSNBC, FOX News, and CNN, among others.  She has presented before the Royal Society of London and on behalf of the Leakey Foundation, and in 2015 she was invited to participate in a White House microbiome innovation forum sponsored by the Office of Science and Technology Policy.  She has been featured in two documentaries, and her current work on ancient Nepal appears in the award-winning children’s book, Secrets of the Sky Caves.

Warinner was named a U.S. National Academy of Sciences Kavli Fellow in 2014, and she was awarded a TED Fellowship in 2012.  Her TED Talks on ancient dental calculus and the evolution of the human diet have been viewed more than 1.5 million times.  For more information on Warinner’s AAAS presentation on the “Evolution and the Ecology of the Microbial Self,”

Science Research in Oklahoma

There is so much science happening right under our noses here in eastern Oklahoma. The OSU Center for Health Sciences is just one example. You’ll find research into biomedical and forensic science, healthcare, medicine, and ,my personal favorite, paleontology.

The cool thing is OSU-CHS has a fantastic resource to help you stay on top of what they’re doing. They call it the Research Spotlight. There are videos and information all on kinds of topics. The video below is one example of the research taking place right here in Tulsa!

 

 

Adventures on Turkey Mountain

Turkey Mountain is a popular place to hike, walk, or ride a bike. Thousands of people go there every year but I wonder how many have stopped to think about the science that’s all around them.

Dr. Stanley Rice recently gave me a personal science tour of Turkey Mountain. He showed me tree fossils and explained that Turkey Mountain is the only place in Oklahoma where a certain oak tree grows. This just shows that science is everywhere. It’s also why you’ll often find me checking out rocks, I’m looking for fossils and evidence of ancient Earth.

This is important-If you find fossils on Turkey Mountain please do not remove them.

(Dr. Rice has been featured before on SIO…click here to see his impersonation of Charles Darwin.)

 

Tools for Digging up Dinos

Ever wonder what tools paleontologists use for digging up dinos? Wonder no more. Here’s the second video from my trip to the Oklahoma Panhandle. (Here’s the first.) It was part of the ExplorOlogy program sponsored by the Sam Noble Museum. We went to Kenton, OK and Black Mesa. It’s home to a ton of fossils from about 150 million years ago.

Dr. Lindsey Yann of the OSU Center for Health Sciences explains the main kinds of tools they use to dig up those fossils and why it’s important to study Oklahoma’s past.

Dr. Yann is the volunteer coordinator for the Vertebrate Paleontology lab in Tulsa. It’s a great place to volunteer if you want to see fossils up close but can’t make it to the Panhandle.

Thanks again to the scientists at the Sam Noble Museum and the OSU Center for Health Sciences for inviting me on this trip.

Digging for Dinos

Who doesn’t like digging for dinos? I had the chance this summer to go on a real-life, honest to goodness dinosaur dig in the Oklahoma Panhandle. It was in Black Mesa near Kenton, OK. That’s about thisclose to the New Mexico and Colorado state lines.

I was a guest of Dr. Anne Weil of the OSU Center for Health Sciences. (She’s been featured before here, here, and here.) The dig was part of the ExplorOlogy program run through the Sam Noble Museum in Norman. ExplorOlogy is all about helping Oklahoma students and teachers get a hands on look at the wonderful world of science. The kids spend the night in the Sam Noble Museum, they get an up close look at the OKC Zoo, and they go work in the field on actual science expeditions.

The dinosaur dig in Black Mesa is an example. The students were helping dig up some Apatosaurus bones. That was a huge dinosaur most of us grew up calling a Brontosaurus.

In addition to digging up the dinosaurs the students went hiking and took a census of the local insects in Black Mesa (video to come!!).

I can’t thank Dr. Weil and the staff at the Sam Noble Museum enough for letting me tag along.

If you know a student who is interested on going next summer click here to learn more about the program and how you can register.

 

This Scientist is OK- Dr. J.P. Masly

Dr. J.P. Masly is an assistant professor of biology at the University of Oklahoma. He studies how genes evolve over time to form complex organisms (like you and me!!).

He recently received an award from the National Science Foundation that will allow him to continue with his research and build educational outreach programs in the community.

He talks, in this video, about why he studies the genes of fruit flies (here’s a hint, we’re a lot a like) and at the 2:15 mark about why he thinks science and religion do not have to conflict.

Another New Dino

I’ve been busy working on a project but there’s always time to talk about the latest dinosaur find. That illustration above is Yi qi. It was found in China and dates back to 160 million years ago.

It’s unique because it’s a theropod that has wings similar to a bat. You can see its long bones in the hand region used to support the wing membrane.

Dr. Jerry Coyne has a great write-up on it on his blog at Why Evolution is True. (Which is also the name of his outstanding book on evolution. It’s a great read to help you get a better understanding of evolution.)

This is what I love about science. It seems everyday a new discovery is made which brings up more and more questions, which spurs more and more research.

Snakes and turtles and stuff

I had the privilege of spending an afternoon with researchers from OU studying snakes and turtles and stuff. Jessa Watters is the Collection Manager for Herpetology at the Sam Noble Oklahoma Museum of Natural History. Herpetology is the study of amphibians and reptiles.

Watters is part of the Cameron Siler lab at the museum. She was joined by two students this weekend at the James Collins Wildlife Management Area in Latimer County, it’s near Robbers Cave State Park. I’ll be producing a story of my visit soon and show why they say studying these creatures is important.

Have Fun with Aquilops

It’s been a while since we’ve checked in with Aquilops americanus. That’s the small horned dinosaur found in Montana by a team that included Sam Noble Oklahoma Museum of Natural History paleontologist Dr. Richard Cifelli.

The tiny fossil is now on display at the museum, but what better way to celebrate this historic find than to have your own version…sort of.

Sauropod Vertebra Picture of the Week is the place to go for the latest news on this awesome little creature. They’ve also passed on some most outstanding ways you can make Aquilops your own. Click here to see how you can make hand puppets, 3D models, even a baby Aquilops for the kiddos. It’s all very cool and a great way to teach kids about dinosaurs.
