    I would like to know how brain cells collectively work together to make each of us conscious, and when they die, of course, that consciousness comes to an end. It seems like the lower forms of life don't have consciousness because they don't have these cells.

    Illuminating! What bugs me is the idea that we all have a common ancestor of the human kind, like a 'mother' way back when. Such bollux assumes a linear evolutionary path which I find quite hard to believe .. all this biblical begetting as if that was always the way. We are the synthesis of many paths yet people want to adore Lucy for example or some mythical ancestor of her's. The LCD approach to genetics is futile, the HCF approach is more likely to shed some light.

    LUCA was probably mesophilic (preferred what we would call "room temperature") or possibly even cryothermic (cold-dwelling), not thermophilic (heat-dwelling) or hyperthermophilic (like hydrothermal vent organisms). The common ancestor of the bacteria probably lived in or around hydrothermal vents, as did the common ancestor of the archaea, but not the common ancestor of the archaea and the bacteria.

  • Tim Meyer

    Why is there only 1 LUCA? If there was primordial soup ponds in various locations around the globe, couldn't it be possible that a different single cell organism came into existence at a different location? Even if a couple million years separated the two different species, couldn't the slow pace evolution allowed each organism to gain a foothold? Even if there was only one primordial pond, isn't it possible that the pond spawned more than 1 single organism? Why must all life evolve from 1 single organism? Why can't some life forms evolve from a different organism? Could some similarities between species been caused by creatures copying a mutation rather than evolving from it? Is it possible there was a second genesis of life on Earth or even more?

    What was so extraordinary those days that out of nothing these #Progenotes appear out of nowhere with genetic information about what. Why now days things don't appear out of nowhere with some genetic information and start a new form of life. I always struck on this question of out of nowhere started big bang and the out of nothing started first single cell organism with I don't know about what genetic information. Is it science or Magic where things appear out of nowhere..

    If the laws of physics work the same at all points in time, it would seem that cellular life should have randomly occurred many times over, and because the building blocks of that life are the same, the basic functions of cellular life would be recreated as well. Like, wheels need to be round, so the wheels that are invented separately by different cultures are going to function pretty much the same way and be made of pretty much the same stuff. Endosymbiosis seems to have happened more than once with chloroplasts, and continues today in Dinoflagellates that are unable to synch the division of their tertiary chloroplasts with their own cell division, and so only one of two daughter cells get the chloroplast, while the other needs to capture a new one. Certainly this doesn't represent a primary endosymbiotic event, but it does show that endosymbiotic events still happen. There is also evidence of at least one other primary endosymbiotic event in a species of freshwater algae, in which the chloroplast retains the peptidoglycan wall of the cyanobacteria, yet the genome of the cyanobacteria is reduced, as in other primary chloroplasts, showing evidence of endosymbiosis, though much less reduced. This puts the endosymbiotic event in the distant past for humans, but in recent history for chloroplasts.
    The same proteins, show up over and over again in various species, like the rhodopsin of some types of photosynthetic bacteria, is the same carotenoid found in our own eyes that allows our retinas to function, because in both uses it allows the capture of a photon and the transfer of it's energy to do cellular work. Though their eyes developed independently, rhodopsin is found in arthropod's compound eyes as well. This isn't evidence that our eyes, arthropod eyes, and photosynthetic bacteria all are closely related, it's evidence that the same chemicals perform the same functions when their constituent parts are arranged in a specific way to produce that greater structure. The function and form are linked.
    Another example involving eyes: The eyes of Cephalopods and Humans evolved entirely independently but both our lenses are made of the same crystallin proteins, and both species developed the DNA to code specifically for it. The same building blocks of amino acids, translated by ribosomes, folded in the same way by various actions, will always produce the same proteins, because the form and function are intrinsic to one another, and both follow the laws of physics and chemistry. A crystallin must be made the same way, because that arrangement of matter creates that thing, and that thing's properties, from it's arrangement, allow it's function.
    Why then do we assume that all life is descended from a single common ancestor? I don't think that the similarities that we see between different phyla necessitate that all life is related by a single common ancestor. That is an assumption. Very simple cellular life could have arisen a number of times, and produced similar results, because life must follow certain chemical and physical laws to function, and the molecular building blocks of life are entirely defined by their form and function. Given the same circumstances it should arise again and again.
    TL;DR I think Wose was right about progenotes.

    What if the universal bit of genome we try to identify doesn't come from LUCA but at some very early stages of live on earth let's say there were hundreds of species of simple organisms and a virus implemented that bit of genome into each and every single one of them, or at least into each and every one that survived and lived to tell its genomic tale?

    I believe there was not one LUCA but multiple. It's possible that the earliest forms of RNA have existed in some kind of a goo, maybe encapsulated by micells of triglcerides (fatty acids + glycerine.).These might have shared molecules, proteines and genes that gave them chemical advantage over other specimen until eventualy some became complex enough to survive on their own.
