Humans have adapted to meet their water needs across disparate environments over time using behavioral adaptations. Yet, as temperatures rise and freshwater sources become depleted, it is critical to understand 1) how populations modify their environments to meet their water needs, and 2) the consequences of these anthropogenic - or human caused changes - on the environment and further on human health. This talk will provide an overview of different global water challenges and focus on a couple ...

Human-made chemicals with the unexpected ability to interfere with our body’s endocrine system have become prominent contaminants in daily life. Because the hormones produced by our endocrine system create complex signaling networks that control our growth, maturation, fertility, immunity, behavior, and sleep, these endocrine disrupting chemicals, or EDCs, can exert powerful biological effects. Declines in human fertility evidenced by falling sperm counts and increases in the incidence of infert...

The world is facing a health crisis due to increasing rates of obesity and diabetes, and the consequences of this pandemic will accumulate over the coming decades. Simultaneously, climate change is accelerating and is already having devastating effects that will undermine our ability to feed the world’s growing population. In turn, our food systems contribute importantly to greenhouse gas emissions, water and land use, and multiple forms of pollution. Thus, a solution to feeding what will be abo...

This CARTA public symposia focuses on the long and short-term impact of humans on the planet that we inhabit, and the consequences for the future of our species. This also gives us the opportunity to celebrate the memory of the late Paul Crutzen, who coined the term “Anthropocene.” It is relevant to ask how a single species evolved the capacity to completely alter the surface of an entire planet and dominate its governing environmental and ecological processes. This symposium brings together exp...

Speakers Leslie Aiello, Michael Purugganan and Vanessa Ezenwa discuss humanity's past, present and future of the Anthropocene. Aiello speaks on how the human capacity to change the planet is not something new, but is rooted in our deep evolutionary past. One of the hallmarks of humans is our large brain size, which began to expand about 2 million years ago. Purugganan discusses how domesticated species are an interesting group of organisms that have co-evolved with Homo sapiens, and have been im...

The ocean is enormous, indeed so large that for centuries we assumed that there was nothing we could do to substantially harm it. Unfortunately, we now know that this is not true. We are having success on some fronts, such as saving species from extinction, protecting ocean waters, fishing more sustainably, and restoring damaged ecosystems by replanting critical species and reducing pollution. Even actions on land, such as removing dams from rivers and rats from islands, can make an important di...

The human capacity to change the planet is not something new, but is rooted in our deep evolutionary past. One of the hallmarks of humans is our large brain size, which began to expand about 2 million years ago. This expansion did not come without consequences, and two are particularly important. The first is the additional energy requirements needed to fuel this larger brain size together with the concomitant life history factors such as shorter inter birth intervals, more dependent offspring a...

Domesticated species of crops are an interesting group of organisms that have co-evolved with Homo sapiens, and have been important in human survival and fitness. We trace the origin and spread of these domesticated crop species over the last 12,000 years, discussing both their impacts on human society as well as to the climate and human evolution. We will also present the challenges in modern agriculture and food security. Series: "CARTA - Center for Academic Research and Training in Anthropoge...

Conservation is common to all societies which learned to live within ecosystem limits. In breaking the evolutionary and biological straight-jackets constricting other species, we became the ultimate multi-niche free-ranging species. Our rise to global conquest and ecological emancipation from nature through domestication and manufacturing expanded conservation for survival to saving whales, elephants, the Acropolis and Mona Lisa. The universal rules for overcoming a tragedy of the commons locall...

Climate change is one of the hallmarks of the Anthropocene. Rising global temperatures are having profound effects on ecosystems and the organisms that inhabit them, including disease-causing organisms such as viruses, bacteria, and parasitic worms. However, much less is known about the potential for infectious agents to contribute to changes in climate. Many infectious agents have the potential to affect greenhouse gas emissions via effects on their hosts. In her talk, Vanessa Ezenwa explores t...

This century is the first in Earth's history when the catastrophic threats to the entire planet can be induced by one species, humans. We have an ever-heavier collective footprint on the planet. We’re empowered by ever more powerful technologies that can be hugely beneficial, but which if misapplied could trigger calamitous setbacks to civilization. Such events could be global: we’re so interconnected that no continent would be unscathed. It’s an ethical indictment of humanity that the gap betwe...

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 Wiessner addresses intergroup ties between humans, chimpanzees and bonobos, explores some of the poss...

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 San Diego professor Carol Marchetto discusses how a comparative gene expression analysis of human and ...

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 condition for it. UC San Diego professor Rafael Nuñez discusses the comparative analysis of “quantit...

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 professor Ajit Varki discusses the importance of Siglec-11 and the paired receptor Siglec-16, and how they p...

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 difference of arcuate fasciculus between human and non-human primate brains and how the specializati...

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 professor Nissi Varki discusses the incidence of carcinomas, including the rarity of occurrence of common hu...

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 known about the capacity of non-human primates with proportionally larger hindguts to obtain phytani...
