Stuff like this is why Amazon is now glutted with garbage AI books that are essentially a scam
This person is a scam artist. They’re offering financing on whatever their “founding membership” is. Evil

Part of my task at Bowie is building classes in vertebrate anatomy and paleontology, and to do that I will be expanding the teaching collection. Anyone have advice on doing so?

I was just looking for papers on fish spine evolution, how fortunate!
Haines et al. show rapid evolution of defensive spines in two lake populations of threespine stickleback in Parc national du Lac-Témiscouata, QC, following stocking of brook trout.

Important to remember our history as a field, good and bad. Great thread.
Founders of modern paleontology, and their contributions to systemic racism, classism and sexism (🧵)
Henry Osborn (1857–1935), responsible for naming of Tyrannosaurus & Velociraptor; president of ANHM.
Co-founder of the American Eugenics Society. Contributing to books later praised by Hitler.

My cat seems convinced there is something under the stove/fridge, a fun addition to the work from home experience. Can’t wait to find out if there’s a mouse or if she’s just messing with me for attention.

Meeting students who are excited to get started in zoology/science is the best part of the job for sure. Especially now that I have a teaching collection of cool animals to show people. Nothing like a frog skeleton to get people interested in zoology.

I am excited to announce that I have accepted a position to serve as a lecturer of zoology at Bowie State University! I am thrilled to have the opportunity to combine teaching and undergraduate research experiences in zoology, paleontology, and ecology.
