A little more info on how glaciers shaped the land would clear up how lakes, valleys and rivers were formed. How thick were these ice sheets? What kinds of artifacts might we find as the glaciers recede.
This is unfortunately a tad late as there is a new epoch proposed and it's based off of radiation levels, genetic evolution in city dwelling fauna, and the change in geologic features like tilt and density levels.
@@marvintpandroid2213I think the "help" in that sentence can imply they don't fully explain it. Communicating through text is really not good for understanding the intent. Like, you're totally right, but idk if that's what they meant.
@@SECONDQUEST yeah they’re not the end all be all of climate science but they help explain certain trends we see in ice cores and ocean bed core samples
Cavemen knew where babies came from and ancient Egyptians were trying to make contraceptives. The only reason we are still arguing about it is because it's politically advantageous for the groups fighting about it.
At the very beginning of this video he says the first life forms were bacteria and viruses about 2 Billion years ago. He then says cyanobacteria showed up around 2.4 Billion years ago. 2.4 Billion years ago is older than 2 Billion years ago. That said, you you have citations or a bibliography to back up the claims of this video?
No, he said there were bacteria and viruses 2 billion years, not that they began then. He well knows, like anyone with at least basic science knowledge, that life began sometime shortly after the creation of the earth and the moon. For the first 2 and a half billion years, there were only bacteria and viruses.
This is not the complete answer but cyanobacteria are the "Blue-green algae" Very simple organism that do not even have a nuclear membrane. They are forced into the bacteria group just so scientist do not have to create a whole new form of life classification for them. To throw a further wrench into the works is that latest finding are that life, on earth, many be over 3.5 to 4 billion years old. Sea vent sediments indicate processes that require life but scientist have no direct connection to what type of life it was (of note is this research was done to find test for any form of life to be done with spacecraft test nearby planets and moons for "signs of life"). Also, one version I read is that bacteria and viruses are at LEAST 2 billion years old, not "started 2 billion" years ago. The statement may not be incompatible, just poorly worded. Hope a different point of view may help.
As an American, I've only ever heard it as "ee-pock." And "eh-pock" and/or "ehpick" has been known on my side of the States as a mispronounciation. I will say that "eh-pock" is the more common mispronounciation; I actually don't think I've ever heard anyone say it as "ehpick" before now.
