    I thought humans came from Mars after the majority of the population stopped believing in science, medicine and higher education, and a select group of people managed to flee the planet during a politicized pandemic and theocratic tyranny.

    Men are from Mars, women are from Venus, and dogs are from Pluto. No, I'm not being Sirius.

    [SIZE=6]Dinosaur footprints dating back 200 million years discovered on Wales beach, researchers believe

    Sauropoda, whose members are known as sauropods, is a clade of saurischian dinosaurs. Sauropods had very long necks, long tails, small heads, and four thick, pillar-like legs. They are notable for the enormous sizes attained by some species, and the group includes the largest animals to have ever lived on land.

    The last time that Wales would have been connected to the mainland before America and Europe drifted apart and thus creating the island would have been around 100 million years ago. Sauropods are not known to swim and for herds of Sauropods to swim the 174 meter deep English Channel would have seen all of the Sauropods drown. 200 million years ago though, much of the West was connected as an entire continent that would have allowed Sauropods to herd to the region known as Wales. Large conifers would have provided the Sauropods with all of the food that they needed. Sauropods had such a large food requirement you could say that they were Mother Nature's first lawn care company. A herd of Sauropods would have toppled a forest in a matter of days. In behind the Sauropods would have come smaller dinosaurs that now found easy prey that had been using the forests as cover but do to the Sauropod's their cover was now gone. But as the Sauropods brought down great forests, new animals would evolve in the wake of destruction left behind.

    Even though sauropods were the dominant herbivores in North America during the Late Jurassic, and though various forms persisted through the Early Cretaceous, the entire group vanished from the continent about 100 million years ago.

    100 million years ago, the continents were well on there way to breaking apart. 150 million years ago is when the last herd of Sauropods from the mainland might have migrated to the island that would eventually become the UK. Being stuck on the island and unable to swim, the Sauropods were most likely wiped out by T-Rex, and not enough conifers to feed their herd as well as not being able to cross to the mainland.

    The People
    The earliest people here that we know about were a (presumably) Homo erectus family who left their footprints on a mudflat in Norfolk about 800,000 years ago.

    With humans having been discovered in the UK 800,000 years ago is interesting for the matter of fact that humans would have had to have had boat making knowledge and the tools to make boats to cross the 240 km English channel.

    Humans could have been on Earth for close to 150 million years and would have settled into regions where Sauropods had once lived and had been chased by T-Rex and then after both died off, newer species emerged in the now forest depleted lands of Wales. Early humans would not have migrated but would have kept to a relatively small area feeding on small game and plants. As the UK broke away from the continents though, groups of early humans, unable to to build boats or tools, would stayed on their island which eventually allowed for faster progress of the human species as larger predatory species that hunted early humans, died out or were killed off by humans. Even 800,000 years ago, humans still wouldn't have developed tools for cutting down trees nor knowledge of building boats, thus putting early humans on Earth, possibly around 150 million years ago.

    200 million years ago is a very long time after the origin of life on Earth, believed to have been somewhere between 3,500 and 4,000 million years ago. Dinosaurs were multicelled, eukaryotic, tetrapod vertebrates like we are. That they might have left trace fossils of their movement is not surprising and this discovery is by no means the first. The descendants of some dinosaurs survived past the Cretaceous–Paleogene (K-Pg boundary) extinction event as birds. Modern humans only arrived on the scene much later, probably within the last 200,000 years.

    ETA: The English Channel formed more recently than 800,000 years ago:

    The claim that humans have been around for 150 million years requires extraordinary evidence other than watching crackpot YouTube videos.

    Not in any way connected with the OP's misinformed beliefs, no.

    For me, reading these threads always reinforces two facts.

    1. We know precious little about that which came before.
    2. We know that - barring a miraculous breakthrough (or series of such breakthroughs) - any advancements needed for true interstellar travel/colonization/exploitation will take countless generations into the future.

    Bring on the Vulcans, I say. A thoroughly (but temporarily) irradiated atmosphere is a small price by comparison.

    Some things may need to be rethought


    Published in Nature Communications today, evolutionary biologists from the University of Reading propose a new statistical model which seeks to explain these sudden changes and long periods of stasis that have been seen in the evolutionary history of some species.

    The team led by Professor Mark Pagel along with colleagues Dr. Ciara O'Donovan and Dr. Andrew Meade, developed a statistical model that reconstructed the body-size changes which occurred throughout the 170-million-year history of more than 2800 mammal species.

    Researchers at the University of Tokyo have for the first time been able to create an RNA molecule that replicates, diversifies and develops complexity, following Darwinian evolution.
