    Question Could it be possible for members from different species like cats and dogs to share the same haplogroup?

    Recently thought of this wild hypothesis: although the cats(feline) and dogs(canine) we see today are two totally different species, there actually existed a common ancestor which both felines and canines descended from known as the Miacidae, or the Miacis, a small, weasel-like insect-eating...

    Out of Egypt?

    I recently noticed something that we had in front of our noses for a while. I'm doubtful of the fact that Africa plays such a big role in our evolution as a species. I'm of the idea that humanity is not a big worker(in the middle of the wilderness). Instead we seek big bodies of water with...

    Rivers essential for humanity/civilization?

    The importance of rivers for the appearance of the first civilizations, that were based primarily in the mastering of an agricultural economy, is a common topic in general culture. The reasons are obvious:abundance of water, therefore food, easy transport and the bigger nets of population that...

    Civilization is good for survival

    We know that civilization is the key aspect of humanity. But, do we?You see, I've noticed that civilization and all the conventions, customs... it comprises; is the only way that humanity has set for humanity, even to the smallest detail. Particularly I want to show you how essential is for the...

    Amazing short videos about science and other topics

    I have found a series of educational videos on YouTube sponsored by various organisations around the world, including the Bill and Melinda Gates Foundation and the Australian Academy of Science. It is called Kurzgesagt, which is German for 'shortly said', but better translated as 'in a...

    90% of species on Earth today came into being 100,000 to 200,000 ybp

    Found this on Phys.org: Sweeping gene survey reveals new facets of evolution "Who would have suspected that a handheld genetic test used to unmask sushi bars pawning off tilapia for tuna could deliver deep insights into evolution, including how new species emerge? And who would have thought to...

    Why aren't humans 'knuckle-walkers?'

    The Ancient Origins of Neural Substrates for Land Walking

    Researchers have determined that the neural circuitry, and genes for walking found in animals, were developed 420 million years before the first little skates (Leucoraja erinacea) and tetrapods. Which is way before the evolution of limbs used for the means of walking movements...

    The evolution of modern human brain shape

    Abstract and symbolic thinking may have began to flourish in Homo Sapiens when our brains became rounder in shape.

    Evolution What species is most fit for life?

    All of them. No species is inferior, or superior to another when it comes to fitness for survival. One may gain a temporary advantage, but it is quickly negated by competition. :good_job:

    Genetic study shows some evolutionary changes humans are currently undergoing

    I don't think there's any doubt that we as humans are currently still evolving; It's not like we would ever stop. Younger-women reproducing, with low-education attainment doesn't necessarily speak about their intelligence. Moreover, more muscular men being favored for selection, and the last...

    Neanderthal's brain matured more slowly than Homo sapiens and other primates

    For those who still thought of Neanderthals as brutish retards, think again. It was already known that they had bigger brains than us, they could talk, buried their dead long before Homo sapiens, used medicinal plants, made and used painting and jewellery, and that they may have invented...

    First Homo sapiens may have appeared in North Africa 300,000 years ago (Hublin 2017)

    Prehistory is being rewritten once again! BBC News: 'First of our kind' found in Morocco The idea that modern people evolved in a single "cradle of humanity" in East Africa some 200,000 years ago is no longer tenable, new research suggests. Fossils of five early humans have been found in...

    The great pairings of Y-DNA haplogroups in prehistory

    When G2a Neolithic farmers started advancing from the Near East into Europe, they encountered indigenous hunter-gathering tribes belonging to various haplogroups (C1a2, F, I*, I1, I2a, I2b, I2c, and possibly even H). Interestingly, most of these lineages didn't survive in significant number...

    Mutation in Coenzyme Q gene defines most major mtDNA haplogroups
