Abstract Coevolution requires reciprocal genotype-by-genotype (G × G) interactions for fitness, which occur when the fitness of a genotype in one species depends on the genotype it interacts with in a...

Lactase persistence (LP), the ability to digest lactose from milk into adulthood, is a classic example of natural selection in humans. Multiple mutations upstream of the LCT gene are associated with L...

In this episode of the Armen Show, Armen Shirvanian interviews Dr. Kaleda Denton, a post-doctoral fellow at the Santa Fe Institute. They discuss the interdisciplinary nature of the Institute, the concept of niche construction in biology, and the dynamics of decision-making, particularly the differences between following the mean versus the majority. The conversation also explores the limitations of game theory, the role of cultural evolution in cooperation, and the impact of AI on accessibility and learning. They delve into the importance of reducing polarization while maintaining diversity in viewpoints, emphasizing the need for mixing and collaboration across different fields and perspectives. In this engaging conversation, Dr. Kaleda Denton and Armen Shirvanian explore a variety of topics including the distinction between majority and mean opinions, the challenges of reading in the digital age, and the implications of large language models (LLMs) on culture. They discuss the importance of communication in society, the influence of close circles versus wider communities in learning, and the role of influential figures in personal development. The conversation also delves into the concept of memes and cultural transmission, the impact of role models on cumulative culture, and the question of human uniqueness in the context of cultural evolution.
