In this episode, Matthew speaks with Tamra Mendelson (@tamram), Professor of Biological Sciences at UMBC.
They talk about Tamra's work studying sexual signal evolution. They discuss the processing bias hypothesis, with a focus on the importance of the ease of processing a signal on the receivers preference for signals. They talk about evidence that efficient processing has shaped human preferences for art and faces, and consider the implications of the same phenomenon in animal signal evolution.
After the break, they talk about ICARE, an NSF-funded Masters program at UMBC that she leads that promotes social and environmental justice by training a diverse workforce of environmental scientists to solve environmental problems.
This week's Two-Minute Takeaway comes from Zeke Rowe (@Zeke_Rowe_), a PhD student at Vrije Universiteit Amsterdam . Read Zeke's paper about camouflage and complexity in moths here.
