CARTA - Anthropogeny (Audio)

This talk considers the effects of the most aggressive ants on the environment, arguing that certain invasive species resemble humans in their capacity for global conquest and environmental destructiveness.  Series: "CARTA - Center for Academic Research and Training in Anthropogeny" [Humanities] [Science] [Show ID: 37772]

UC San Diego professor Carol Marchetto discusses how a comparative gene expression analysis of human and non-human primates revealed differences in the regulation of a class of transposable elements LINE1 retrotransposons between species. University of Southern California professor Joseph Hacia discusses studies profiling phytanic acid levels in red blood cells obtained from humans and captive non...

This symposium addresses several important distinctly human characteristics that range from molecules, to metabolism, anatomy, disease, and behavior. Goals include transdisciplinary interactions, improved self-understanding, promotion of ethically sound studies to explain known differences, and the generation of new, potentially unexplored, insights on uniquely-human specializations. Given the int...

Unlike our closest primate relatives, chimpanzees and bonobos, humans form strong intergroup ties which can mitigate coalitionary aggression and make peace possible. However, such bonds can also be used to build larger alliances that take such conflicts to a new level of magnitude, supported by cultural and linguistic proficiencies. Arizona State University and University of Utah professor Polly W...

Identifying cellular and molecular differences between human and non-human primates is essential to the basic understanding of the evolution and diversity of our own species. While preserved tissues are the main source of comparative studies between humans, chimpanzees and bonboos, the samples do not accurately represent the traits of live cell behavior and cannot be genetically manipulated. UC Sa...

Emory University professor Dietrich Stout discusses an evolutionarily motivated definition of technology that highlights three key features: material production, social collaboration, and cultural reproduction; UC San Diego professor Pascal Gagneux discusses how recent comparative genome studies have revealed that this polymorphic system is ancient and shared between humans and non-human primates,...

Arizona State University and University of Utah professor Polly Wiessner addresses intergroup ties between humans, chimpanzees and bonobos and explores some of the possible evolutionary developments that contributed to the human disposition to form mutually supportive external bonds, and then discusses the impact of social ties on coalitionary action; UC San Diego professor Rafael Nuñez discusses...

Technology is clearly central to human life and evolution but remains hard to define and study. Emory University professor Dietrich Stout discusses an evolutionarily motivated definition of technology that highlights three key features: material production, social collaboration, and cultural reproduction. This perspective has important implications for the way we conceptualize and study the origin...

Humans and many other species have biologically endowed abilities for discriminating “quantities” to some degree (e.g., subitizing), but only humans, via the distinct capacity of “symbolic reference” exhibit “number” — i.e., exact symbolic quantification. Language, with its symbolic properties although present in all human cultures, is a necessary condition for “number” but it is not a sufficient...

Sialic acid-recognizing immunoglobulin-type lectins (Siglecs) are a family of cell surface proteins prominently expressed on immune cells in mammals. Siglec-11 is an example of an inhibitory Siglec. It was the first protein in the brain found to be “human-specific”: non-human primates express Siglec-11 in other tissues but not in the central nervous system. UC San Diego School of Medicine professo...

Language is a human cognitive specialization, and as such, is expected to be supported by human neurological specializations. The arcuate fasciculus is a white matter fiber tract that connects Wernicke’s and Broca’s language areas in the human brain, and also connects the homologues of Wernicke’s and Broca’s areas in non-human primate brains. Emory University professor James Rilling discusses the...

During embryogenesis, the three germ layers (endoderm, ectoderm, mesoderm) differentiate into epithelial and non-epithelial cells, which eventually form differentiated tissues and organs. Abundant data now indicates that we humans are very closely related to other hominids including chimpanzees, bonobos, gorillas, and orangutans, the so-called "great apes". UC San Diego School of Medicine professo...

Diet has played a major role in the evolution of human and non-human primate digestive systems. Phytanic acid is a potentially toxic branched chain fatty acid that can be acquired in humans by ingesting plant and/or animal products. Although it was established that humans cannot derive phytanic acid from chlorophyll and instead normally obtain it only from meat, dairy, and fish products, less was...

ABO Blood groups represent the first described human molecular polymorphism. The ABO gene encodes variants of a protein (a glycosyltransferase) that produces the short sugar chains on glycoproteins and glycolipids that define the A, B, or O antigens. These antigens are found on red blood cells, plasma glycoproteins, and other cell types in various tissues. Individual humans can have one of four bl...

Humans are unusual in that we depend on shared foods, especially among families and friends and between potential mates. Food sharing occurs between healthy individuals and those that are infirm or elderly. We also differ from other great apes in our early ages at weaning, late ages at maturity, short birth intervals and survivorship decades past menopause. The emergence of these patterns was cruc...

Discussion session about The Evolution of Human Physical Activity. Series: "CARTA - Center for Academic Research and Training in Anthropogeny" [Science] [Show ID: 37188]

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species? Herman Pontzer explores the evolution of metabolism, Grazyna Jasienska discusses different effects of activity on women's reprod...
