Two big ideas in biology: the evolution of species via mutation, fitness and natural selection; and the embryological development of individuals, from fertilized egg to whole organisms. How do these two big ideas-“evo-devo,” as it’s called-relate? What novel ideas emerge?
Featuring interviews with Alex Rosenberg, Alan Love, Rachell Powell, and Terrence Deacon.

I might have said this before but if Closer To Truth produced a video that was just a mega-compilation of clips of Robert Lawrence Kuhn walking around pondering while looking cool I would watch it.

This is my exact field of evolutionary biology, and I worked in it in the 1980s and wrote my Ph.D. dissertation on mechanisms of macroevolution ("speciation") that are altered during early development of the individual organism. This can cause sudden macrochanges in anatomy that result in new species or even genera in just a few generations.

Given the diversity of life forms, it’s astounding to note the similarity in the developmental genetic toolkit

@simonhibbs887 4 ай бұрын

It seems like that toolkit must have evolved very early on, and was inherited by all the life forms we see today from a common ancestor.

Using embryology (which is part of zoology, not botany or microbiology) to reimagine organismic evolution, and conversely using evolution to reimagine embryology, are surely useful exercises. But the current waves of this effort will likely be reinvented once more in the coming decades because of multi-omics, tech-enabled approaches to classifying the range of variation above the genome: epigenome, transcriptome and translatome, functional proteomics, then in a different scope, the metabolome and its processes that build the structures of cell, tissue, organs, organ system, individual organism, family lineages of organisms, and social groups in some (contingent) environmental niche. I was recently impressed by efforts to come up with expanded cell type classifications, that are exploiting the convenient shotgun approach of transcriptome analysis as a key level, while still relating it traditional morphology of cells (including the development of cell lineages, and embryology) and layers of organization above or after the transcriptome, as well as layers before and below. As data about cell types in different species becomes available (initially they are working on model organisms mouse, marmoset (maybe more convenient to work with than the macaque) and humans, evodevo will have to reimagine itself based on an expanded vocabulary of what are the pieces, the actors, involved in evolution and development. Clearly, with their choice of initial model organisms, they are interested in the evolutionary connections, especially in brains.

There are organizational vectors(ie evolutionary) that drive this at many scales. From very large as in solar influence to very very small involving Quantum processes that become functional drivers of neuronal /brain development. (I just made that up)❤

Should corporeal organisms evolve while the spiritual or mental does not? Does the evolution of mental development have any impact on the biological or vice versa? With such biological evolution, how does it open new doors and pathways in cognition? The more i learn about all such physics and teleology i find myself always alluding to mind, Nous, Cit. If you try reducing everything to mere matter and particles, there's just no way it could work that way. So Nous i acknowledge.

22:49 this is an example in science that resembles evolutionary development; an early figure in a field makes some remarkable observations and starts the process of founding a field of inquiry but because the field is so new, these important observations lack the theoretical context to describe them. As a result, incorrect explanations get embraced and passed on by their followers in the field. It can take a long time and a lot of work for the false explanations to get weeded out because the views of people working in the field and their view of the founder and his contribution became constrained early on. We eventually get to the point where we can recognize a founder and his ideas as important for starting a science while not being overly invested in everything he “discovered”.

@capitalistdingo 4 ай бұрын

Like how lots of what Aristotle “knew” turned out to be wrong but his contributions pushed knowledge forward anyway.

What if one would consider Evolution as part of the fourth dimension. The Earth evolves,is it alive.A life cannot be unless it has sparked into existence.space driving development,time driving evolution.

Science is so fractured into disciplines we're now used to 3 Big Words Acronym for any field of study. Which is good on one part, the complexity of our models should try and keep up to world's entropy, but on the other we're not hive-mind-like enough to communicate and digest disparate discoveries quickly. It's overwhelming, a race lost from the start. Hopefully we're close ti a paradigm shift that compresses our theories in a more sensible way. Like idk assembly theory might be a candidate for a continuum between physics and biology, or cognitive and social psychology, so that they fit well and don't seem at odds like they do at the limit of our current theories

Why he keep out brains development? Brains evolution explains reality biology. However guys doesnt know How brains is so important. They are Focus in biology development It is NOT utter shows up biology development . Brains show up biology development reality. For instance brains perceptions biology proceendings not biology show up reality to the brains.

Kuhn, you have repeatedly mentioned fine tuning, life, consciousness etc are due to accident of luck, but you never made a video explaining it, most physicists/scientists, often claim so without clearly explaining. Your viewers want a scientific explanation. Please.
