The chapter delves into the phenomenon of polyploidy in both plants and animals, exploring its evolutionary implications and genetic consequences. It discusses the importance of polyploid speciation in creating new species and the adaptive nature of such events in different ecological niches. The conversation extends to specific studies on amphibians, highlighting how polyploidy influences competitive advantages and species diversity in varying climatic conditions.
In this 226th in a series of live discussions with Bret Weinstein and Heather Heying (both PhDs in Biology), we talk about the state of the world through an evolutionary lens.
In this episode, we discuss a new breakthrough in plant genetics: polyploid potatoes and corn from Ohalo Genetics, which are claimed to double the harvest from individual plants. Beginning with a discussion of naturally occurring polyploidy in other species, including frogs, we analyze the discussion of Ohalo’s new products with an evolutionary lens. Is it possible that biotechnology can evade trade-offs, or is this utopian thinking in the corporate world? Why do so many mistakes of modernity come in the form of people accustomed to complicated systems, applying their knowledge to complex systems? Finally: does Terrence Howard (recently on Joe Rogan) have a predictive model, or is he just blowing smoke?
