The Story Of Rodinia

13 posts in this topic

This is just a little story i like to share on occasion. Its based on scientific evidence, but to those who do not know the story of Rodinia, it can be viewed as a nice story instead :P.

Long ago, roughly a billion years ago, the super continent Rodinia emerged. Much like Pangea (which many seem to know more about), Rodinia was the compilation of many continents, gathered around the equator of the planet.

The massive super continent brought about great changes to the planet. It stripped the atmosphere of its warming gases, and its orbital cycles created a cool freezing affect. Its massive size disrupting oceanic circulation.

Eventually, around 800 million years ago the entire planet froze over in a massive sheet of ice a mile high.

But it wouldnt last forever. The rifts in Rodinia eventually pushed its pieces apart. The vulcanism from within it warmed the planet and gases re entered the atmosphere. As continents moved away from the equator, their reflectivity was less effective at cooling the planet. And so, the majority of ice retreated, leaving a new warm temperate environment.

The newly rifted supercontinent had at this point increased surface area from its rifting and created great warm temperate havens for the first complex lifeforms to explode in population on earth. This occurred around 600 million years ago with the ediacara biota and the ensuing cambrian explosion.

And thats about it :P. And so, in a general way, here we have the story of the first complex life on earth.

My wording isnt exactly perfect, but if anyone is interested in particular details feel free to ask, likewise if anyone is familiar with this material and is interested in pointing out potential errors in my translation from research to general story telling, feel free to speak up.

Alrighty, adios all.

I got a potential problem with the bolded part...

U arent talking about Humans just appearing out of nowhere?

Ah, this is roughly 600 million years ago. To put this into perspective, dinosaurs were around roughly 250 million years ago. And we're much younger than the dinosaurs, at...well depending on what stage were talking about, humans at 400 thousand years ago.

So this is, before the time of humans.

By "complex", im referring to morphological, anatomically advanced. Living things beyond prokaryotes and eukaryotes.

I wonder what the islamic perspective is regarding the creation of other species.

i dont know the islamic view on creationism in regards to the animals and stuff.

I remember this story. Thank you for refreshing for it for me (it has been awhile since I researched in the field on Geology)

I wonder how many people actually know of the ediacara biota. Often i hear people talking about the first man and women, ya know, Adam and Eve. But where are the people talking about the real first humans? or the real first complex life.

This is the first complex life.

Think about what it means, and how it relates to who we are.

I still feel in the dark regards Islamic perspective on creation / genesis and what the 6 stages of creation mean, Adam and Eve and then putting it all in context

Fascinating post would like to know more on this topic

Ah, didnt notice people had replied.

There are many stories I could tell, though they are all on different topics.

For this particular one though, I just kind of simplified things from a geology course. Evidence can be found in things like...

Well, its geology. When you look at the earth, you can apply concepts to assist you with understanding events. Concepts like superposition and cross cutting relations. Uniformitarianism, original horizontality. And of course, understanding details about the fossil record assists, combined with geologic concepts to bring about the stories that can be told.

The animals of the cambrian, those that came about in the cambrian explosion, post ediacaran times. These fossils can be found in the Burgess Shale of Canada.

Aside from that, looking into things like plate tectonics brings clarity on continental movement and where they have been in the past.

Things like geomorphology and concepts related to the milankovich cycles assist with our understanding of ice ages and the formation of ice, over time.

There is also a bit of chemistry involved in relation to atmospheric changes and alterations in global temperature.

So, there are many things that can be discussed. Many evidences for the story of Rodinia, all brought together into one.

To help better explain my prior comment. If a quantity of parent or daughter material were added to the rock, post crystalization, one mineral of the batch or perhaps many or all of them, wouldnt hold a straight line in their representative quantities.  If the rock were completely melted and recrystallized, the rock would have essentially reformed and there would be no linear data to speak of.

 

So, this means of radioactive dating essentially cross checks itself.  It alone is its own calibration.  It is Rubidium strontium dating (as it sometimes may be carried out).

 

Oh! posted in the wrong topic~!
