Fantastic, No obnoxious hyperbole, pumping music or over produced verbal twaddle. Just the facts accompanied with gentle background music and a great selection of comb jellies showing all the detail needed. Great job of introducing this phylum.
Until a few years ago, sponges were thought to be the first animals on the evolutionary tree. However, newer research suggests that ctenophores (comb jellies) are the first true animals, not sponges. Scientists first sequenced the genome of the earliest comb jelly, the sea walnut (Mnemiopsis leidyi), and compared it to several other species of comb jellies to determine that they split from the animal kingdom’s common ancestor before sponges
I was just doing some reading up on this and have some lingering questions. Is it possible that one or more species diverged before the comb jelly and simply didn’t make it to modern day? They came to their conclusions about the comb jelly by analyzing the arrangement of genes within its chromosomes and seeing that the locations of its genes most closely resembled that of the original organism. So, without samples from organisms who may have died out long ago, is it possible to rule out that they may have diverged first? This really has me going down the rabbit hole 😂
Was snorkeling today and ended up in the middle of a ton of these things got worried at first but then realized if they sting I would have already been stung. was quite the experience though
I remember finding out about this, there’s a debate right now about whether sponges or comb jellies were the first to split from the common ancestor of animals
Oh my god. My mind is blown. Especially at the fact they predate and hunt but don't have a brain?!! I can't get my head around that as predating on prey seems to be a complex task that would require a lot of reasoning ability and "brain-power", and yet they don't have one! If anything can enlighten me how this is the case
Personally I think ALL THEIR NERVES put together act as some kind of a brain but all in stringy pieces ... just because the NERVOUS SYSTEM THEY HAVE DOESN'T seem to RESEMBLE any parts of a brain ... come on , how are they able to hunt ? It CAN'T be all totally reflexive ... ? Even if one set of nerves can taste or smell the water and some other nerves can sense how close by a creature is ... I still think their whole nervous system ... COMBINED DOES COMPRISE a BRAIN .... just not as we know it .
Sure... because the mind isn't the brain. The same reason why there are people alive with only half a brain 🧠 OR even just a brain stem. Where is the consciousness ? 😮
I know I'm only six years late but you might want to listen to this again because it's actually very nice it's very chilled or not yelling at us for trying to be hyped up .
Better microphone, better recording environment that doesn't sound so hollow, mix the VO at least +3db hotter. I recognized after the fact I was probably ripping on a video a kid made, so that does, in fact, make me the douchebag.
An another interesting life created by God. But, not the beginning of all animal life. All life began within the words we read in Genesis Chapters 1 and 2.
