CARTA: Comparative Anthropogeny - Language: Uniqueness Out of the Ordinary with Eva Wittenberg
January 01, 2024 21:00 - 23 minutes - 230 MB VideoHuman language is a strong contender for the title of most often named species-specific feature in the literature. But why is that? In this talk, Eva Wittenberg explores what we could mean by "human language", and how different conceptions of language inevitably lead to different answers about whether it is species-specific. While syntax is a central feature, it is only one of several, and the uniqueness of human language is that it arose from a combination of, perhaps, ordinary ingredients. ...

CARTA: Comparative Anthropogeny - Did Humans Evolve Concealed Ovulation? with Pascal Gagneux
December 29, 2023 21:00 - 23 minutes - 213 MB VideoHuman ovulation lacks visible signs, unlike chimpanzees and bonobos with conspicuous genital swellings during fertility. This led to the concept of "concealed ovulation," seen as a human adaptation. Proposed reasons include encouraging paternal investment, confusing paternity to deter infanticide, enabling secret mating and female choice, and reducing female rivalry. Many non-human primates also have unsignaled ovulation. While self-reported human mating doesn't match ovulation, debates persi...

CARTA: Comparative Anthropogeny - The Evolution of Shorter Inter-birth Intervals in Humans with Corinna Most
December 27, 2023 21:00 - 19 minutes - 241 MB VideoLife history theory suggests that inter-birth intervals (IBIs) depend on a trade-off between maternal investment in current and future offspring, influenced by the mother's energy and somatic maintenance. Normally, IBI aligns with maternal and infant body size, larger relative infant size leading to slower breeding. In contrast, humans have relatively shorter IBIs due to cooperative breeding, support from the social group. Some other species with cooperative behaviors also exhibit shorter IBI...

AI Agents That Do What We Want
December 15, 2023 21:00 - 56 minutes - 550 MB VideoResearchers used to define objectives for artificial intelligence (AI) agents by hand, but with progress in optimization and reinforcement learning, it became obvious that it's too difficult to think of everything ahead of time and write it down. Instead, these days the objective is viewed as a hidden part of the state on which researchers can receive feedback or observations from humans — how they act and react, how they compare options, what they say. In this talk, Anca Dragan, Associate Pr...

CARTA: Comparative Anthropogeny - Delayed Neuronal Maturation in Humans with Carol Marchetto
November 23, 2023 21:00 - 20 minutes - 155 MB VideoSince humans split from their primate ancestors, their brains evolved with a larger mass relative to body weight, more cortical neurons, and distinct connectivity patterns. Human neurons mature more slowly, a trait known as neoteny, likely influencing these differences. Gene regulation, not new genes, may underlie species differences, particularly in the primate lineage. The role of these regulatory mechanisms in human neuron development remains poorly understood. This lecture explores the mo...
