Over one-fifth of native North American pollinators at elevated risk of extinction – Research News

https://www.floridamuseum.ufl.edu/science/over-one-fifth-of-native-north-american-pollinators-at-elevated-risk-of-extinction/

A pivotal new study led by NatureServe reveals that more than 22% of native pollinators in North America are at an elevated risk of extinction. This first-of-its-kind, taxonomically diverse assessment evaluated nearly 1,600 species—including bees, beetles, butterflies, moths, flower flies, bats a
We also have a lot of plant diversity, which begets insect diversity.

DNA duplication linked to the origin and evolution of pine trees and their relatives – Research News

https://www.floridamuseum.ufl.edu/science/gymnosperm-origin-evolution/

Plants are DNA hoarders. Adhering to the maxim of never throwing anything out that might be useful later, they often duplicate their entire genome and hang on to the added genetic baggage. All those extra genes are then free to mutate and produce new physical traits, hastening the tempo of evolution
A new study shows that such duplication events have been vitally important throughout

https://www.floridamuseum.ufl.edu/science/genome-sequencing-of-butterflies-resolves-centuries-old-conundrum/

When conditions are just right, organisms can undergo rapid bursts of diversification, and what starts out as one species can end up as an entire family tree in the evolutionary equivalent of the blink of an eye. A new study published in the journal Proceedings of the National Academy of Sciences

Mammals are a bit odd when it comes to bones. Rather than the bony plates and scales of crocodiles, turtles, lizards, dinosaurs and fish, mammals long ago traded in their ancestral suit of armor for a layer of insulating hair. Armadillos, with their protective and flexible shell of imbricated bon
