    Man won’t be around as long as the dinosaurs. Because we’re so stupid.

  2. Pippa pig

    I think dinosaurs were so big because of the atmosphere was rich in oxygen and nitrogen.

  3. Bitte Bilden

    Damn you cats!

    So, the saying "we're more alike than we are different" has more than 1 meaning.

    I wonder what would happen if cats were bred for behavior. I wonder if it would be possible to breed a whole new type of cat. 🤔

    Where did the rain come from if the earth was arid prior to said rain?

    Quinkana never died out in Australia until forty thousand years ago!

    So basically.... We are like virus: We can reproduce, but one can not do it alone. We can evolve, obviously. Produce no energy but wastes a ton. No control over internal environment, being bodily or emotional. I see a pattern here......

    How scientists gathered all of this information is absolutely incredible

    Man...cats do NOT "need" humans. If we don't clean out their litter box, that bothers US, not them. They'll just find another poo-place. If anything, they have domesticated US. I mean, we keep them, and that means we have to clean up after them.

  25. Jeremy Thomas

    Feral cats are a huge problem in Australia wiping out heaps of native species.

  26. King Rama

    This is what happens when you let dinosaurs use fossil fuels

  27. Defiant_ace _x

    Cats aren’t domesticated change my mind

  28. KraggleWulf

    Well I know where my sex drive comes from now.

  29. Duck Milk

    .......so, what I've learned: 1. Dogs are dogs. 2. Cats are still the kings of the land. 3. No bears in Africa. Because cats.

  30. first last

    But arthropods don't have a circulatory system I thought? That's why insects can't grow too thick because they need to get oxygen from opening in their exoskeleton which can't penetrate very deep, I thought?

  31. brooklyn560

    A half billion years of evolution, just for us to clog it with red meat cheese and fried food

  32. Just Looking

    There was no quirk. 30,000 yrs ago there was an unknown catastrophe & the human pop. Dropped to 3,000 on entire planet.

  33. Nich Hodge

    I think that cats believe they have domesticated humans!

  34. nouman khan

    Why did we domesticate cats for gods sake?

  35. Alex Zuniga

    Who high af rn

  36. Zeus Melendrez

    entertain this thought: what if what we know were staged by the so called “archeologist” dun dun dun duuhhhhhnnn 😳😳😳😂😂😂

  37. Arun Rai

    Then that damn Squirrel started chasing acorn 😂

  38. Lurid Phaesporia

    Super interested in the criteria of domesticated animals. What are some examples of animals that have been permanently genetically changed by human influence, yet are not reliant on humans in our world today? Can’t think of any off the top of my head but I probably will after I hit post here LOL

    1. Lurid Phaesporia

      Just realized any answers are probably gonna be really sad. Bummer.

    I grew up in Darwin, in Australia's remote tropical north. There was a Dragonfly about 6 inches long, and yes it was green, so it looked like a military helicopter. There was also a Stick Insect about a foot long, it could fly and had crimson wings.

  50. Erika

    We never domesticated cats. Cats domesticated us. 🐈

  51. Ricardo Rojas

    But did you see it ?

    If only the Trilobites had taxed people into poverty and spread a Socialist fantasy of controlling the weather....

  57. robert charlton

    we all have mitochondria? is there a cure?

  58. Winkler

    I watched the video to the end and my final thoughts were.... the female host is very attractive... There's no hope for humanity.

  59. Craig Wall

    My name is Craig...dweller of the crag. I definitely have burrowing tendencies.

  60. Lindsay Williams

    What about studying the genes/DNA of indigenous people? I feel like that could show a lot of information

    Penguins are semi aquatic dinosaurs, change my mind

  65. PurpleRhymesWithOrange

    Human extinction will most likely be self-inflicted.

  66. PigIron BigIron

    Why is your nose crooked? Can we talk about this?

  67. maurizio aschero

  68. Dana Kelley

    Your not going to read this comment because there's thousands and I'm transvestite who eats plumbs.

  69. bo0tsy1

    Yeah, they always seem feral to me. Maybe title should be attempted to domesticate.

  70. Trixie Leonard

    Don't forget cave bears being mistaken by early greeks as demigods, being buried with full warrior honours, and then ancient greeks found giant people dressed in full armour and weaponry and figured they must have existed at some point. Bears look very human without fur/muscle

  71. Trip Derham

    I've never even heard of Antartica

  72. Pake Zerbonia

    What's the animal pictured that it's taking down?

  73. Averon God of fire

    “Felis catus” of thats some Tolkien level naming

  74. C N

    I can see Ned Flanders going back in time to stop this from happening.

  75. victor soto

    So, Native Africans, who never migrated and met others, are the only "true" Homo Sapiens. There is more diversity of DNA in Africa than anywhere else in the world...the more diverse, the genetics, the healthier the body. The combination of inbreeding and interbreeding, by western man, has diluted the bloodline of "true" humans.

  76. kk kkk

    I feel like of all the prehistoric animals, dinosaurs are on the tame side

  77. Pat Rick

    I find it interesting how we domesticated dogs and cats twice

  78. Thomas Watts,  Jr.

    I'm all about science and history....and because of this I am all about science and history...so this thing about "this is the only evidence we have, except for this other really rare (as if it's not all RARE) evidence which we will ignore because it doesn't fit the theory" thing REALLY bothers me. There is NOTHING wrong with saying "we think" whereas stating opinions and theories as fact is ALWAYS wrong. STOP IT

  79. bob8mybobbob

    The distant past is so mind-boggling. At one point all the animals were just scooting around slurpin' up plants, not really worried about anything but finding more food. Then one day one of them was like "No, Bob, I'm going to eat you."

    Funny how most dinosaurs have only 1 or 2 fossil examples, but dragons and griffins didn't exist because we dont have a fossil of one. Humans couldn't have been around back when dinosaurs were around also even though there are numerous fossils and other artifacts that prove otherwise.

  90. Candy Jones

    Boring video.

  91. Dusty151

    So you’re saying the earths temperature increased without human involvement and it didn’t end in 10 or 12 years?
