Evolution. Repost, but it's hilarious.. the size diference is because the oxygen content of the atmosphere being much lower today. Its biologically impossible for reptiles to grow so large now

What? I'm sorry, but like 250 million years ago when the large reptiles first came about, the Earth had about half as much oxygen in it's atmosphere as it does now. I don't get what you're trying to say.

not sure on your sources but after the great oxidation event (~600 mil year ago) O2 levels in the atmosphere reached about the level they are today (at ~400 mil year ago) before a rapid increase of oxygen levels ~300 million years ago that could have been as high as 1.6 times the levels observed today. Oxygen is needed for synthesis of the ATP molecule via the ETC, which allowed for the reptiles and bugs of the time to grow to such immense sizes. The levels leveled out to about the same as they are now a little before 100 million years ago which is why dinosaurs fossil size decreased towards the end of their appearance in the fossil records.....

your looking at percent.... not atms. Rise in nitrogen levels are not an indication of a fall of oxygen levels
#16 to #15 - longboarding (05/07/2013) [-]
The green is the oxygen levels.
#17 to #16 - scullyossis (05/07/2013) [-]
oxygen levels by percent. heres oxygen levels by atmospheric pressure. red is high, green is low

haha you made me second doubt myself for a bit. i do evolutionary research with RNA and this was one of our projects to trace back conditions of O2 and Fe(II) for the past 4 billion years

What a ******* tease!
You have no arms, so evolution gives you some arms and takes all your badassery away and makes you into some slenderman retard parrot. Then it takes away your arms again, making you eve more useless. Then it's like, "hey, sorry about all that, so we're going to give you some wings," but guess ******* what, you can't ******* fly!

So many master trollers in comments, and so many idiots that think they're being serious. "omg evolution is real kiddo, I'll wreck you up with knowledge son!" ******* morons...

They say the T-Rex might possibly had feathers.
The picture is made By Sammy Hall.
Im okay with it, if it looked anything like this. Though we might never know...
#49 to #43 - aerosol (05/07/2013) [-]
I like the archaeopteryx more than any other dinosaur because it's the closest mother nature has come to making a dragon. Maybe not in terms of loos alone, but as far as physical structure goes...
#57 to #49 - darknesincontrol (05/07/2013) [-]
Here's a 3D artist rendering of it, it looks awesome as a bird
#59 to #57 - aerosol (05/07/2013) [-]
I prefer the illustrations. Mostly for the color.

Yeah its pretty cool creaure, giving in the right artist hands^^

I just google archaeopteryx to find an artist rendering of it, and this thing came up!
Oh god, it gives me the chill

No idea about the T-rex, but I do know archaeologists have stated that velociraptors did have feathers.
User avatar #55 to #53 - darknesincontrol (05/07/2013) [-]
yeah one of the thoeries with the feathered T-rex, is that many of its close relatives had feathers
User avatar #56 to #55 - jakefenris (05/07/2013) [-]
Do any of the fossils have the feather nibs on them?
User avatar #60 to #56 - darknesincontrol (05/07/2013) [-]
cant really say for sure, but probably not. But since they say that was no evidence for or agianst it having feathers, then they might have found some fossils of a confirmed feathred dinosaur, without any leftovers of their feathered coat. Maybe, i dont know :P

wait, so evolution goes from gigantic, man eating, terrifying dinosaurs to delicious, harmless birds? and you see this as a bad thing?

evolution supposedly makes things bigger, faster, smarter yet it turned dinosaurs into birds....the whole theory sounds like a desperate attempt to explain reality without God.
User avatar #73 to #25 - tomtomat (05/07/2013) [-]
Look, it didn't turn T Rex into a bird. T Rex died... remember? The giant astroid 65 million years ago? The animals that survived the blast were the smaller ones. Like birds. This picture is just for ***** and giggles (Mostly, anyway).
User avatar #27 to #25 - yourbaus (05/07/2013) [-]
not necessarily bigger, but more efficient
#29 to #27 - John Cena (05/07/2013) [-]
how the **** does an unguided, unconcious mechanism KNOW how to make something more efficient? if you believe in evolution, that's fine. but just be consistent with your worldview and kill yourself. after all, you're just a bunch of molecules in motion and life has no objective meaning
User avatar #33 to #29 - yourbaus (05/07/2013) [-]
it doesnt. i could explain it to you, i feel like you havent learned it completely yet.
#34 to #33 - John Cena (05/07/2013) [-]
blah blah natural selection blah blah random mutations blah blah. it's all gibberish to me. not because i don't understand it, but because it's complete nonsense
#40 to #34 - palindromia (05/07/2013) [-]
Well if the Earth were to suddenly freeze over to near uninhabitable temperatures, it is likely that the fat people with a lot of body hair would survive to reproduce and the world would repopulate the human species as fat and hairy.
This is natural selection. The characteristic which BEST suits the environment are the ones who survive to reproduce. Obviously, fat, hairy people aren't stronger and faster than skinny people but their characteristics are what best fit the environment for survival.
Now imagine this process only with a million more changes over millions of years.

The simplest way I know how to explain evolution.
#75 to #40 - ngxd (10/16/2014) [-]
That's not evolution. That's survival of the fittest. Sure, survival of the fittest plays a part, but evolution also involves natural selection. Just describing survival of the fittest whilst trying to explain evolution is like telling people how to create a while loop, but not specifying which programming language you are talking about. It's nonsensical.

Anyway, you described survival of the fittest very well. I'm impressed.

Side note: Wow. My first comment is a rant. Technically.
#76 to #75 - palindromia (10/16/2014) [-]
I know it's not evolution. What I'm describing is natural selection as the mechanism by which evolution functions.
User avatar #41 to #34 - cyanskater (05/07/2013) [-]
Are you trolling? Evolution makes perfect sense, and it has nothing to do with any "knowing" force. It's a natural process which is guided by the organisms themselves. Individual organisms that can reproduce, do so. Individuals that can't, do not. Therefore, the individual genes which are "successful" become a bigger part of the population, and eventually the species overall adapts due to changing environments. Not that hard of a concept bro; it's all about procreation.

i understand how it supposedly works, but i'm not convinced that it's true. this is not a difficult concept
#66 to #63 - KungFuZerO (05/07/2013) [-]
If you understood how it worked, you would see the insurmountable evidence for its truth. Can u give one good reason why it would be in every credible science textbook in the world?
User avatar #35 to #34 - yourbaus (05/07/2013) [-]
you could have said it nicer
User avatar #70 - shodaihokage (05/07/2013) [-]
I was just thinking...over the course of thousands of years we could take a population of rats and make the undergo natural selection by killing one off with undesirable traits. Technically speaking we could make these rats evolve into pikachu!
