Out of the Ashes: Dawn of the Age of Mammals | HHMI BioInteractive Video

Ғылым және технология

Sixty-six million years ago, a giant asteroid struck the Earth. It wiped out 90% of all species, including all the large dinosaurs. How did life on Earth recover after this mass extinction? This video follows paleontologists working at a fossil site near Denver, Colorado. Their discoveries, along with discoveries from other sites, have allowed scientists to piece together how ecosystems recovered and changed in the aftermath of the asteroid.

    The Early Palaeocene is one of my favorite periods for this exact reason. I've always been fascinated on how long it took plants and animals to recover and how Earth's landscape looked back then. Please do more documentaries on the Palaeocene period!

    For me too. Also the earliest Triassic is fascinating. I would also like to find a list, exhibition or documentary of most species so far known that survived these major extinctions, before they evolved into new things. Sort of the Creme de la Creme of the preceding age, that live in a changed world.

When was the moment, when one of us went left, and the other one went right? Was that in the final, 65 million years period, after the KT-event? Or was it before?

    you can get a job as amateur excavator pretty easily. my brother used to assist in roman burial ground excavations. pretty sure its the same with paleontologists. because they want cheap or volunteering work force to do the hard work. its usually volunteers and students doing it. but some dig sites are pretty big so they want more people you do the hard work of hauling rocks around and digging, archeologists or paleontologist will come with brushes afterwards and then you stay quiet to get near them, dont touch anything and listen to them what was cool about almost 2000 year old skeletons on first glance from even an amatuer was that their teeth were pretty healthy, nice natural shape, and white. shows how refined sugars are destroying our teeth in modern times

    mammals diverged around the same time as reptiles did from basal amniotes.. amniotes diverged into synapsids, diapsids and anapsids synapsids into mammals, diapsids into reptiles, and anapsids into (debatably)turtles and bunch of other extinct animals... all around the same time so yea, mammals were around long before kt extinction event. they just didnt manage to adapt fast enough to be competition to the dinosaurs. which proved in the end to be a lucky advantage because mammals more easily survived the extinction event because of being small and able to burrow

    Its also worth noting the continental states were almost ground zero as far as the asteroid was concerned, the vegetation recovery was probably quicker in other regions farther away, so chances are some broad leaf trees were already germinating soon after the initial impact winter in more secluded areas. The same is true for mammals, btw, in Western NA only 4 to 6 species of mice-sized mammals survived the impact, and, as far as we know, they might not had been ancestral to any of the later Puercan North American mammals (unless Protoungulatum turns out to be a basal ungulate, but that's debatable), newer species sort of pop out in the fossil record, which likely means they were immigrants from Asia through Beringia or Europe through Greenland, with even some exchanges from South America being possible, unfortunately we have a very poor fossil record from that age in those places 😅

    To try to tech this stuff without visually showing cladograms and explaining the morphology over time from clade to clade is almost pointless. It's more of a jumbled mess.

    Because of these difficulties, some leading theorists have abandoned the Miller-Urey experiment and the “primordial soup” theory it is claimed to support. In 2010, University College London biochemist Nick Lane stated the primordial soup theory “doesn’t hold water” and is “past its expiration date.” \fn{13 [13.] Deborah Kelley, “Is It Time To Throw Out ‘Primordial Soup’ Theory?,” NPR (February 7, 2010). } Instead, he proposes that life arose in undersea hydrothermal vents. But both the hydrothermal vent and primordial soup hypotheses face another major problem. *Casey Luskin* *The Top Ten Scientific Problems with Biological and Chemical Evolution

    It’s called palatalization. It’s really common in English. It’s also the reason why brigge became “bridge” and scip became “ship”. Considering the word comes from the Latin ‘speciēs’, pronounced more like ‘spek-ee-ays’ (in the Classical pronunciation), it’s hard for us to judge what may be the ‘correct’ pronunciation in English! ‘Spee-sheez’ is the preferred variant in the UK. Elsewhere, it can vary.
