Friend, let me show you something most of us were never taught concerning how the world was created. Logically. Let the word of God be true and very man be a liar -Romans 3:4 Here we go… Genesis 1:1 In the beginning, God created the heavens and the earth. Ok, but do you see it? Do you see the Trinity of “time, space, and matter” in this verse? Let’s break down the word of God. “In the beginning” = TIME “God created the Heavens” = SPACE “and the Earth” = MATTER This goes deeper because Time, Space, and Matter each have their own trinity. Trinity of Time = Past Present Future Trinity of Space = Length Width Height Trinity of Matter = Solid Liquid Gas The very first verse of Gods word in His Bible is everything used to create and measure the physical world we live in today. This is irrefutable. Friends… God is real. Jesus is real. Heaven and hell are real and so is the devil and his demons. Macro and micro evolution is a lie from the devil to deceive you away from the truth of Gods word to mankind. Don’t be deceived. All glory and praise to The Most High God! Thank you.

Notice all of the climate change and extinction level events. This is what happens throughout history. We can’t prevent it or lessen it’s effect. No ‘taxation’ or special congressional bills passed, will change it in any way. All of you morons screaming and throwing tantrums about how we horrible humans are destroying the planet, will not make a gnat’s ass of difference. The world’s governments are well aware of the ‘next’ event (2046) and are using ‘climate change’ as an excuse to enslave the masses and enrich themselves at your expense, building deep underground bunkers, where they and the chosen elete, think they can ride it out. It’ all bullshit folks. Don’t buy into it…..Do some research and you’ll clearly see what’s going on…

Love the graphics. This vid helped solidify my loose understanding of early Earth: iron banding; snowball earth etc. I would like to have seen a bit on the evolution of cell structure (ie. nucleus vs no-nucleus). Visit the channel. Click on "videos" (otherwise it says there is no content). There are some great titles that I can't wait to watch.

How are they dating the earth as rocks can't be dated except through geology (layers) and trapped carbon which of course would all be rock or oil by now. Plus all the radioactive decay would be based on when it was created in supernova NOT when it reached earth. Except specific rocks which have two datable radioactive elements together in a rock which still doesn't deal with the issue of when they formed (as this dates the rock NOT the "planet". Thus how can you find the right stone from the right age with the right radioactive elements (2 dif ones) and deal with when they were created in supernova, travel time, etc etc... Unless decayed from very large unstable elements on earth, but that still doesn't tell you when.

Anatomical features that we see as adaptations are not selected for by natural selection. They aren't subjects of natural selection. Instead, they are the residue, or what remains after natural selection proceeded to eliminate whatever worked poorly or didn't work at all. Adaptation is not designed. It's what remains.

Well said. If they do not die they continue to increase breeding pools that will descend with genetic modification. But we are used to explaining things as if the function came first instead the death being the selector. ru-vid.com/group/PLXJ4dsU0oGMLnubJLPuw0dzD0AvAHAotW

Hi Lizzy, Did Eukaryotes evolve from prokaryotes during the Archaean era? And do we have transitional fossils of that? If not, what kind of evidence do we rely on to substantiate it ?
@lizzysgambelluri4710
@lizzysgambelluri4710 5 лет назад
Hey there! So eukaryotes arose from prokaryotes during the Proterozoic eon, which was the last eon of the Precambrian supereon. The first eukaryotes that arose were single celled organisms. The evolution of multicellular eukaryotes arose later in this eon after the meltdown of Snowball Earth, in which a high amount of niches were available and, more significantly, there was a significant increase in atmospheric oxygen (thanks to the activity of photosynthetic organisms). Now unfortunately, we do not have transition fossils of the first diversification event that occurred, as these organisms were soft bodied and thus did not fossilize. There are some fossils that provide evidence of the major diversification and evolutionary events of multicellular eukaryotes during the Cambrian explosion (Cambrian; Paleozoic). As far as transitional fossils between prokaryotes and eukaryotes at that time in history, there are no specific "fossils" per say, but there is evidence of such. The major source of evidence stemming from the theory of endosymbiosis, which proposes the creation of eukaryotes from prokaryotes by phagocytic activity. Essentially one larger cell engulfed a smaller cell and incorporated that smaller cell into its cellular composition. This is what is used to explain the prokaryotic relics that are the mitochondria and chloroplasts. It is thought that these two organelles evolved from bacteria living in large cells. In general, it is proposed that eukaryotes arose from prokaryotes through symbiosis - in other words, teamwork. Collaboration. By engulfing smaller cells, larger cells could take on selective advantages provided by the cells that were engulfed, while the cells that were engulfed continued to survive and got a nice cozy home in the process. Again, we do not have "fossil" evidence of such transition, BUT there is evidence. That evidence is molecular, arising from the prokaryotic based characteristics found in mitochondria and chloroplasts. Particularly the mitochondria. Like prokaryotes, the mitochondria has its own cellular membrane, a circular DNA genome, and reproduces through fission, just like bacteria.
