Showing results for "the great courses" in Evolution & Genetics

Epigenetics is the science of living DNA, charting the chemical pathways that spur DNA into action by turning genes on and off. While the Human Genome Project of the early 2000s was hailed as the key to understanding human heredity and disease, that historic effort was just the beginning. It has taken epigenetics to fill in the picture, explaining how the fixed code of our genome is implemented in countless living processes.

Imagine a world without bees, butterflies, and flowering plants. That was Earth 125 million years ago. Turn back the clock 400 million years, and there were no trees. At 450 million years in the past, even the earliest insects had not yet developed. And looking back 500 million years, the land was devoid of life, which at that time flourished in a profusion of strange forms in the oceans. These and other major turning points are the amazing story of evolution.

In 10 riveting episodes, paleoanthropologist Elen Feuerriegel takes you on an unrivaled tour of the human fossil record in search of the biological and behavioral underpinnings of our very “humanness”.

Today, with relatively easy access to our DNA ancestry, we have more data about ourselves and family history than previous generations could have imagined. In the 12 fascinating lessons of Identity in the Age of Ancestral DNA, Anita Foeman, PhD, professor of communication and media, and founder and primary investigator of the DNA Discussion Project at West Chester University, takes us behind the scenes to examine what really happens when individuals receive their personal DNA ancestry results.

Since the publication in 1859 of Charles Darwin's remarkable On the Origin of Species, the modern science of biology and genetics has added surprising new dimensions to evolutionary theory. In this course, you’ll discover what Darwin didn’t know, covering much of the curriculum of an introductory college course in evolutionary biology. No background in science is needed to follow these engaging lectures, delivered by Professor Scott Solomon of Rice University, a gifted teacher and widely traveled field biologist.

Locked inside the DNA of every species that ever lived are endless stories - about origins, ancestors, fate, and much more. Until recently, these secrets were completely inaccessible. But with the help of new technologies, scientists are now reading the hidden history of DNA, making remarkable discoveries about ourselves and our fellow species. Your gateway to this treasure trove of information is Unlocking the Hidden History of DNA, 12 informative and accessible lectures delivered by New York Times best-selling author Sam Kean.
