Even cooler, this is what happens if the digital flowers in our algorithm are "toxic" (cost you points when you click them): they evolve warning colors. Boom. Aposematism.

In case you were wondering, here's what our genetic algorithm looks like when you're "playing" it. The flowers start out pretty colorful, but they evolve pretty quickly to match the background (which we set as a purple-red in this iteration). Green bar means a "hit", white means a "miss."

Virtual "flowers" evolving camouflage in response to human selection pressure over generations in a Python algorithm we wrote (the video snapshots of the whole population over time). Evolution - it just happens.

Brownfields are greener than you probably think. Abandoned industrial spaces can actually have higher amounts of animal activity - and more species diversity - than parks, suburban yards, and even (in some cases!) primary growth forests.

When Helene hit Appalachia it left roughly 750,000 (back of napkin estimate) crayfish in ONE riverside soccer field on the Radford University campus. So... A) the number of crayfish in our rivers is totally crazy and B) that's absolutely one hell of a natural selection event.

Can migrating birds predict the weather that they're about to fly into? And, if so, how do they change their physiology to compensate? That's the question. Spending a lot of our fall sunrises in cow pastures is how we try to find an answer. Ecophys life :)
