Evolution

Speakers V. Ramanathan, Nancy Knowlton and Jonah Western discuss humanity's past, present and future of the Anthropocene. Veerabhadran Ramanathan has had the privilege and pleasure of collaborating with Paul Crutzen for more than 40 years. Crutzen is one of the most creative, innovative and original geo-scientists of his generation. Nancy Knowlton speaks on how the ocean is enormous, indeed so large that for centuries we assumed there was nothing we could do to substantially harm it. Unfortunately, we now know that this is not true. David (Jonah) Western emphasizes how conservation is common to all societies which learned to live within ecosystem limits. If we use our unique capacity for cooperation and planning, there is hope for combating global warming and sustaining the diversity of life globally.

Brenna Henn (Stony Brook Univ) explores patterns of genetic diversity across Africa and models for modern human origins in this talk. She discusses whether genetic data is concordant with archaeological data and suggests directions for future research.

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 difference to marine life. Of course, we still need to do much more, and do it faster. In the future, we can turn to new tools drawn from the natural and social sciences. Big data and genetic interventions have a role to play, as do ocean-based renewable energy sources and new financing schemes. Perhaps most important is the growing recognition that success depends on empowering local communities in efforts to create a healthier ocean.

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 and longer periods of growth and development, and longer lifespans. The second is the solution to these energy requirements that involve cooperative breeding and the development of the high risk/high return hunting and gathering foraging strategies. From this foundation we trace the increasing capacity of humans to extract more energy from the environment through the development of a reliance on fire, the agricultural revolution leading to the industrial revolution and modern times.

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 Anthropogeny" [Humanities] [Science] [Show ID: 37771]

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 locally offers hope for combating global warming and sustaining the diversity of life globally—if we use our unique capacity for cooperation and planning.

Veerabhadran Ramanathan has had the privilege and pleasure of collaborating with Paul Crutzen for more than 40 years. During the year 2000, when he announced to the world about his Anthropocene concept, Crutzen and Ramanathan were in the midst of a major field study on Atmospheric Clouds over the Indian Ocean. Crutzen is one of the most creative, innovative and original geo-scientists of his generation. Ramanathan describes the Anthropocene using the lens of a climate scientist. He concludes with speculation about how and when we will transition from the current adolescent age of the Anthropocene subject to multiple assaults on the environment to a mature, sustainable and safe Anthropocene.

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 the idea that interactions between climate change and infectious diseases are not solely unidirectional, specifically, that climate change can increase disease prevalence in human and animal populations, but disease, in turn, may exacerbate climate change.

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 between the actual state of the world, and the way it could be, is widening rather than narrowing. COVID-19 has been a wake-up call. It has shown that our increasingly interconnected civilization is vulnerable - but also that well-directed science can be our salvation.
