    The sole purpose of anything "living" is to reproduce. If one can do it without getting up from the couch, then the better. Viruses reproduce using the energy provided by the host. All other attributes of "more complex" life are solely for reproduction - respiration and metabolism, growth, response to environment, even the cellular environment.

    It has been obvious for many years, even decades, that the human caused extreme climate change story is a scam. They fiddle the figures- that much is known, the CO2 causes climate change theory was debunked over a century ago- that is another fact, even if CO2 concentration makes a difference still humans contribute less than 0.2% of all greenhouses gases, they could not make no measurable difference anyway. Even when everybody realises it is a scam we will still be told we are all wrong, and they will continue the plan which suits the people who are in a position to carry out the plan- and that is very different to what suits the interests of ordinary people.

    Those small as a dog prehistoric animals that dissipated were not horses, It is like calling a house Cat as been the same as a Tiger. There are different animals and should not be called the same. Horses that the Spanish brought to The New World were much bigger and stronger. You cannot call a house Cat as a Tiger..

    Latest studies show that non-coding genomes are really not that silent. For example, non-coding DNA in intron located near loci modulating heart function actually produce micro-RNA that can down-modulate messenger -RNA transcribed from that regulatory loci. Varieties among these non-coding DNA influence whether organism survive heart accident or not among other things. Thus, it is highly probable that it is selected for. This should call the mollecular clock's validity and accuracy into questions.

    Love the show guys. You should consider doing one on the common ancestor of cats and dogs with other living species that descended from it as well.

    Is there any evidence the ratites are actually related any more than other birds? If they lost flight independently, maybe they just all lost flight. Are old world and new world bats (or monkeys) closely related?

    Well, how do I put it. Being hunted and killed by a large strong animal is one of the best ways to lose a life. You at least know it wasn’t out of anger, and you know you’d not have been able to defend yourself on your own, but you still have some chance. I’d always pick some big cat since they are supposedly quick killer.

  • Kayenne54

    5:30 Taking a cat to my mother's; had my passenger window open literally 2 inches, and the cat flattened itself like a snake and almost escaped while I was driving. I've since theorized that cats are descended from snakes. Laugh if you like but look at that skull. And then there's the cat like predilection for "sunning itself". My overall theory is that most species are descended from reptiles anyway. Seeing as how reptiles preceded us mammal-like species anyway, apparently.

    It does make sense that ice at the equator might not only be thin but constantly cracking and breaking open only to freeze closed again due to tidal bulging. The moon was a lot closer back then so the tides would be comparatively much stronger than they are today

    Ok third time I try to post this comment, why does it keep disappearing?I get you may have gotten some odd comments on this video but there's nothing inappropriate about mine: You could also have a situation where some closer relative ape migrated to Eurasia at some time after the first apes but before the dawn of man.

    It’s not that hard for them to travel because they would’ve had dugout canoes and even better water skin canoes which can reach sizes of up to 3 x 10 m! And it’s only takes about 2 to 4 years walking to get from one side of erasure to the other and considering they had it’s of thousands of years to do this!
