Episode notes

i think a better way of thinking about it is that the cell is a whole, like the macros likethe larger simbion was. The archea sort of got smaller bacteria living within it, and those bacteria got sort of coopted being a part of this new uchareotic cell. They can't divide on their own any more but they still have a remnant little geno. So if you lookat it inside a mitocondran, it has its own geno which is one of those things that made people realize forty years ago, oh, my gosh, like these things were once free living, separate cells,.

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.
