It’s the beginning of December and more than a month since we’ve had a Forum Friday, but since most people were either still enjoying their Thanksgiving dinners or fighting through crowds of shoppers, I opted for a Monday meeting. October was a busy month and November followed suit. Most of what we posted on Paleoaerie since the last Forum was a rundown of the Society of Vertebrate Paleontology annual meeting in Los Angeles. A huge amount of material was presented at the meeting, of which we barely scratched the surface. We also reviewed The Big Golden Book of Dinosaurs, a great book for elementary kids.
We covered a lot on the Facebook page. Evolution in medicine got a lot of attention, including a whole online, open-access journal about it. We learned about evolutionary theory being used in the fight against the flu, malaria, HIV, and cancer, twice, no three times! We even learned why we have allergies, and if that isn’t enough for you, we found a whole series of papers on evolutionary theory in medicine for you.
Studies of human evolution had a good showing this month, starting with a new skull of Homo erectus changing our views of our ancestors and a book called “Shaping Humanity: how science, art, and imagination help us understand our origins.” We learned how women compete with other women and how natural selection can be tracked through human populations.
Modern experimentation has demonstrated how life may have gotten started chemically and how clay hydrogels may have helped. We watched the evolution of bacteria in a lab over 25 years. We also learned how evolution can evolve evolvability.
Evolution outdid itself with deep sea animals eating land plants and an amazing mimicry display. We learned why bigger isn’t necessarily better, why monkeys have colorful faces, and that large canines can be sexy.
In addition to all the news from SVP, we learned about two new giant theropods, the tyrannosaur Lythronax and the allosauroid Siats. We also learned about the toothed bird, Pelagornis and pachycephalosaurs. We also learned about research on what modern animals tell us about dinosaur brains. We also saw evidence that the Mesozoic may not have had as much oxygen as we thought.
Dinosaurs weren’t the only fossils of interest to be announced. A new unicellular organism is providing insights into the evolution of multicellularity. The oldest fossil of a big cat and a suction-feeding turtle were found, as well as the oldest known fossil ever, providing evidence of life almost 3.5 billion years ago. We read the beginning of a series on the evolution of whales and how the first tetrapods crawled onto the land. We learned about fossil giant mushrooms and watched the Red Queen drive mammals to extinction.
Putting 3D images of fossils on paleoaerie has always been one of the goals of the site and the potential for this to revolutionize geology has not gone unnoticed. The Smithsonian has taken up the challenge. If you want to learn how to do it, here is the paper for you.
We celebrated Alfred Russell Wallace and American Education Week. Along the way, we listened to the great David Attenborough describe the history of life and Zach Kopplin tell us about his efforts to keep creationism out of public schools in Louisiana.
For educational techniques and resources, we looked at BrainU and a website by the ADE and AETN. We examined the usefulness and pitfalls of gamification. We saw how to build your own sensors and use them in class. We discussed how to change people’s idea of change through business concepts the truth about climate change. We even saw doctoral dissertations via interpretive dance.
Do you have any gift ideas to share? Any of the stories particularly pique your interest? Let us know. Don’t just talk amongst yourselves, talk to us.
Time for another Forum Friday! As always, please leave comments about what you liked and what you would like to see more about. What did you think about our stories? Do you have a book or show you want reviewed? Have any resources you would like to see discussed? Have you made an interactive or other resource that you think might be beneficial to others? Let us know.
On Facebook we celebrated National Fossil Day and Earth Science Week, looking at fossilized arthropod brains, new skulls of Homo erectus and what that means to our understanding of human evolution, how cartilage helped dinosaurs get so big, and learned about the origin of flowering plants. We learned a website letting you make your own geologic time chart. We found a great video discussing what phylogenetic trees are and how to interpret them.
Going along with Earth Science Week, we found special Earth Science Week resources and a STEM Student Research Handbook put out by the NSTA, as well as resources available at Scitable. We discussed the pros and cons of the NGSS and the benefits of preschool education.
We learned about unusual deep sea creatures off the East Coast, more ways to tell moths and butterflies apart, how Black Skimmer birds can skim, and how the arapaima’s armor protects them from piranha. We saw how color evolved and its role in mimicry, how hands came before bipedalism, and how epigenetics affects evolution (it’s not just about mutations).
It’s your turn. What do you want to talk about?
