Evolution

Fish showed up in the fossil record about 500 million years ago, and today, they are the most diverse group of vertebrate animals on the planet. Phil Hastings, Scripps Professor, and Curator of the SIO Marine Vertebrate Collection, will discuss the global diversity of fishes. Series: "Jeffrey B.

This symposium presents varied perspectives from earth scientists, ecologists, and paleoanthropologists on how climate may have shaped human evolution, as well as the prospects for the future of world climate, ecosystems, and our species. Elizabeth Hadly begins with a discussion about A Tipping Point: Using the Past to Forecast Our Future, followed by Naomi Oreskes on Human Impacts: Will We Survive the Future?, and Veerabhadran Ramanathan on Climate Change Mitigation: In Pursuit of the Common Good.

The oxygen content of earth’s ocean has changed dramatically through time, beginning with essentially no oxygen and rising to present-day levels, with important consequences for the evolution of life. Oxygen levels in modern oceans are also shifting as a consequence of global warming. Learn how low-oxygen settings in the modern ocean can inform us about the “explosion" of animal life more than half a billion years ago, mass extinctions, and the future our ocean.

This CARTA symposium addresses the question of how human language came to have the kind of structure it has today, focusing on three sources of evidence. One source, which is discussed in these three talks, concerns neuroscientific investigations of functional specialization for language in the human brain and its dependence on the linguistic input the language learner gets during cognitive development. Evelina Fedorenko (Massachusetts General Hospital) begins with an examination of Specialization for Language in the Human Brain, followed by Rachel Mayberry (UC San Diego) on How the Environment Shapes Language in the Brain, and Edward Chang (UC San Francisco) on Neuroscience of Speech Perception and Speech Production.
