As a developmental biologist, molecular clock studies have long suggested that animals split from choanoflagellates >800 million years ago. There's evidence of something like 10 whole genome duplications, and many of the important signaling proteins involved in animal multi cellularity during that time, these genes would not have been selected for if these organisms were living as single celled organisms. It makes a lot of sense to me that the systems that pattern embryos would have taken at least a couple hundred million years to reach the level of sophistication seen in all modern animals, including sponges. If all of this happened in little multicellular ball like organisms that look vaguely like blastulas - which is the stage when these pathways are particularly active, that makes a lot of sense. Molecular clock studies often put the dates for these major milestones way earlier than fossil evidence. Paleontologists often respond by saying that molecular clock studies must be flawed (they are not perfect), but the fossil record is also incredibly biased towards large bodied animals with hard bones and shells, it's a little niave in my opinion that we will find fossil representatives of every major evolutionary transition at the earliest time point.
@stacie15957 ай бұрын
This is such an interesting comment! I am simply a lay person but it did stand out to me that those cells started as singular and became multicellular throughout their life cycle, just as animals do! We all start as a sex sell and become these incredibly complex life forms so it's not surprising to me that earliest ancestors started much the same.

@BenTajer897 ай бұрын
@@roseannelajara8659 Also my blastula comment makes it seem like I subscribe to Haeckle's flawed "ontogeny recapitulates phylogeny" hypothesis. I don't, but studying the pathways that patterned embryos I have wondered the situation where they all started. The problem with embryonic patterning genes, is that they are the ultimate chicken and egg question: you seemingly can't get the patterns without the genes, and but you wouldn't select for the genes without the patterning. There are three signaling pathway families: TGF-beta/BMP, Wnt, and Shh, that were made almost completely from scratch between the split with choanoflagelates. Each one of those signalling pathways needs about 4-6 minimal unrelated gene components in order to work. So to me it seems natural that there had to be a long period of time where these systems evolved and played out. And I've wondered, what the heck did this animal (can it even be called an animal) look like? One appealing answer is that maybe they looked like sponges. From a signaling standpoint that would make a lot of sense because a morphology based on repeating units would be more robust to screwups than a more symmetrical body plan. But there's a decent amount of evidence that that sponges didn't come first. The other alternative is that it was maybe something with a single axis, but also very small.

It allows for the idea that this is only what we could "see" in 1930 and there most likely were things going before then, just that we couldn't see them. Part of the "pre-Cambrian" period has been renamed (well, the name was ratified in 2004) the Ediacaran as some things we could see with the eye came to light and we are of course delving into techniques that can see with more detail. The cells here were 10 microns wide.

It’s recently been shown that sponges possibly went back 750 million years, if not even older. Them and comb jellies were likely the first forms of life, and the life forms that survived Snowball Earth. Before that and multicellular life was little more than amorphous blobs of cells. Eyes, skeletons, and differentiated tissues only evolved during the Ediacran and Cambrian periods. Comb jellyfish were basically bigger cells with cilia and everything, whereas sponges had harder tissues, but had no symmetry whatsoever.

Do this: average tectonic movement = 1 inch per year. How many years of tectonic movement makes 1 complete trip around the earth? Multiply circumference in miles 24,901 x feet in 1 mile 5280= 131,477,280 earth circumference in feet. Multiply x12 to get inches in Earth circumference = 1,577,727,360. Using average 1 inch of tectonic movement per year, and there are 1,577,727,360 inches in earth circumference means it takes that many years for 1 complete trip around the earth. But tectonics start as 2 plates moving away from each other at a common source of newly made earth. Meaning the plates will meet again in half the circumference. So divide inches 1,577,727,360 by 2 = 788,863,680. It takes that many years for the 2 plates to meet on the other side. Those plates subduct, travel vertically to be churned up and later become new earth again. And that's the reason the fossil record cant really go much further back than 788 million years. Because all living things get churned up and evidence destroyed. But there are pieces of plate that churn under but reappear mostly intact. So there are anomalies of creatures without prior history. And tectonic movement is not the same everywhere but 1 inch per year is ok to use just for a rough estimate and pretty closely matches the fossil record.

@@michaelmoore7975 Yes and no. The center of land mass for each plate, called the shield or craton, generally does not go through subduction. The cratons host some of the oldest known rock formations from 3-4 billion years ago. While the process you mention is certainly part of it, I would argue weathering and erosion processes are a larger reason why we don't find many older types of fossil. If not for erosion we would expect to find more in these older rock formation areas.

This, that is the Burgess shale and Ediacaran deposits, Cambrian explosion and the evolution of metazoa is something I studied extensively before switching to geophysics for grad school. No one, that I know of, within the field thinks metazoa magically appeared, the issue is we had no fossils, certainly not of the quality of the Burgess or Ediacaran deposits. We always assumed that colonial forms were extant long before things as complex as hallucigenia or anomalocaris, we just didn't have fossil evidence. Also, Darwin never really went into this, the book is titled On the Origin of Species, not the origin of life, or animals. He proposed the process of speciation from preexisting forms through environmental pressures, i.e. survival of the fittest, that is those best suited to fit the conditions within which they existed.
