Have you ever wondered how humans originated from apes or why birds look different based on their environments? Evolution and natural selection are the answers to those questions! What is evolution and natural selection? How does it work?

Survival of the Fittest! Evolution with Dr. William Ratcliff

How did life go from single-celled to multi-celled? Dr. William Ratcliff is an Associate Professor and Co-Director of the Interdisciplinary Ph.D. in Quantitative Biosciences at the School of Biological Science at Georgia Tech. Dr. Ratcliff and his collaborators are working with single cells of yeast, watching them make the jump to become multi-cellular organisms. It turns out, life has done this many times in the past, and not just the jump that created the modern animals we know of today. https://biosciences.gatech.edu/people/will-ratcliff 🚀 OUR WEBSITE: ════════════════════════════════════ https://www.universetoday.com/ 🚀 PODCAST LINKS: ════════════════════════════════════ RSS:                https://universetoday.com/audio iTunes:           https://universetoday.com/itunes Spotify:          https://universetoday.com/spotify 🚀 EMAIL NEWSLETTER: ════════════════════════════════════ Read by 50,000 people every Friday.

832: Jumping to Multicellular Life with Dr. William Ratcliff

We’ve talked about the very origin of life, but certain transitions along its subsequent history were incredibly important. Perhaps none more so than the transition from unicellular to multicellular organisms, which made possible an incredible diversity of organisms and structures. Will Ratcliff studies the physics that constrains multicellular structures, examines the minute changes in certain yeast cells that allows them to become multicellular, and does long-term evolution experiments in which multicellularity spontaneously evolves and grows. We can’t yet create life from non-life, but we can reproduce critical evolutionary steps in the lab.Support Mindscape on Patreon.William Ratcliff received his Ph.D. in Ecology, Evolution, and Behavior at the University of Minnesota. He is currently Associate Professor in the School of Biological Sciences at Georgia Tech.
