Dr Doug Wallace will join Joe LaManna, the Jeanne M. and Joseph S. Silber Professor of Brain Sciences, Physiology and Biophysics, CWRU

Oxygen is precious for life, but too much of a good thing causes us damaged vision, nausea, breathing problems and ultimately convulsions! Every mass extinction in the history of the earth coincided with a fall in ambient oxygen whereas high oxygen produced dragonflies the size of seagulls and monstrous cockroaches. As cool as giant bugs are, too much oxygen in the atmosphere makes trees spontaneously burst into flames! When they do, the CO2 released brings the O2 levels back down. So the earth self-regulates almost like a living thing itself. But this wasn’t always the case. For 2 billion years the ancestors of mitochondria and chloroplasts were free agents –free living organisms seeking their fortune on their own. How these critters came to throw their lot in with cells like ours is a very curious story indeed! Even more amazing is how their symbiotic evolution changed the face of our planet in a geological heartbeat –without which humans could never have evolved! Today, scientists can map genetic disorders to mitochondrial DNA and use mtDNA’s rapid evolution and inheritance through the mother to track the origin and evolution of humans as they have moved throughout the globe.

The Origins Science Scholars program began on campus in 2009 and has become a favorite venue for Cleveland area folks interested in or curious about cutting edge science with topics changing every semester and ranging from the beginning of the universe, to the origin of the earth and solar system, to the origin and evolution of life on earth, the human mind and consciousness, and evolution and human health.
