Episode notes

We're pretty sure that archia m ifu arose from the midacondra. We have a mixture of archel stuff and bacterial stuff in our cells. Our lipid membrane is actually bacterial. It's not archel ther us, a dfferent kind of chemistry in their lipids,. Which which make the membrane of the cell. And we think that actually came over from the um, from the midACondra.

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.
