- Cooper Bison Skull: The Hunt (Part 1) 013In 1994, archaeologists were investigating an ancient arroyo that contained evidence of three, separate, large bison kills by Folsom culture hunters. In the middle kill, they found a painted bison skull. It's the oldest painted artifact ever discovered in North America. In this episode, Dr. Leland Bement tells what his research indicates about this hunting technique and the possible significance of the Cooper Bison Skull in the hunt.23 min
- Missing Links Episode: Trees 012
There is no single botanical definition of what makes a plant a tree, but there are certain features that we use to identify trees. This episode explains what a long-lived, woody perennial is and highlights some of the records setting trees on Earth.
12 min - Pleistocene Megafauna Extinction 011
The Pleistocene is known for the large mammals that lived during the “Ice Age” and the mass extinction of the mammalian megafauna that occurred as it ended. In this episode, I talk with Tom Luczycki and Dr. Hayley Lanier from the Sam Noble Oklahoma Museum of Natural History to learn about the Pleistocene megafauna of Oklahoma and the probable causes and consequences of their extinction .
34 min - Tree Thinking 010
With a tree diagram and the simple phrase “I think” written next to it, Charles Darwin gave us a new way to look at evolution. This episode explains the basic principles and processes of reading phylogenetic trees called tree thinking. Dedicated to Dr. V. Funk, the greatest cladist.
19 min - Charles Darwin’s Mail & Notebook 009
This episode commemorates Darwin Day 2021 by looking at his contributions to evolutionary biology from the perspective of an old mystery and a new one.
26 min - Missing Links Episode: Systems & Models 008
Systems are an important biological concept for understanding the world around us. In this Missing Links Episode, I explain what systems are, how systems are described with models, and how systems have emergent properties.
8 min - Missing Links Episode: 2020 Top 5 Stories 007This episode runs down the top five science stories that caught my attention in 2020. This is a new shorter episode format called Missing Links. We hope you enjoy!15 min
- Unprecedented 006One of the things that you hear a lot lately is that things are unprecedented. To evaluate whether that is true or not, we need to compare the present to what has happened in the past. In this episode, we look at the 1918 Influenza Pandemic and what we can learn from it to determine what is and perhaps what isn't unprecedented with COVID-19.30 min
- The Botany of Halloween 005
The Halloween that many people think of with candy and trick-or-treating is dramatically different from the ancient traditions of Samhain. This episode of BioTA explores the origins of Halloween and its botanical iconography. So, pull up a seat, get a little closer to the fire, and bundle up against the October wind as we celebrate Halloween on Biota.
21 min - Bloodsucking Vectors 004
Ticks are not just parasites that like to attach to animals for a blood meal, they can also be incredibly important vectors for spreading viral, bacterial, and parasitic pathogens to their hosts. In this episode, I interview Dr. Heather Ketchum, a medical, veterinary, forensic entomologist to learn what ticks do, how they transmit diseases, and what you can learn from a maggot. [note: Like many things now, this interview was conducted via video conference, so please excuse a few sound glitches.]
