Dr. Matthew P. Scott

President,

Carnegie Institution for Science



Carnegie Astronomy is also part of Carnegie Science and the study of all living species. From ancient single-celled organisms evolved multicellular animals whose immense numbers of specialized cell types—skin, muscle, nerve—allow division of labor. Each cell type forms in the right place, is suited to its task, and activates certain genes. Powerful cell-to-cell communication systems organize structured tissues such as lungs, limbs and brain. Dr. Scott will discuss half-billion-year-old genes that have been gradually modified to give rise to the vast diversity of animals.



Partial funding for Carnegie Observatories' 2015 Astronomy Lecture Series was provided by The Kenneth T. and Eileen L. Norris Foundation. The lectures were hosted by A Noise Within (http://www.anoisewithin.org/). Video production by Neighbors Video Services (http://www.neighborsvideo.com).
