I find it interesting that some animals, like comb jellies and many flatworms, still use cilia to move around. It's likely that before muscles evolved, the first multicellular animals used cilia for locomotion. In other words, the nervous system evolved to control the cilia, not muscles.
i think human consciousness is clearly a different level of understanding, but to say it has zero understanding would be like saying that my cat also has zero consciousness simply because it isn't human. also, the algae was selective about what it chose to eat, indicating a level of consciousness.
how do u find those i was lookin at algae at 400 times mag. and i couldnt see anything moving just algae. also i have a dish of leaves dirt and stuff and i cant find anything in there
Just to point out, cilia and flagella are the same things. They are structurally identical. Flagella are just longer and the 2 got found at different times and thought to be different so got very different names. I'm all for the Paramecium with the massive engine power!
what would you call it when it chooses to reverse direction to move back towards its food? it seems like it is conscious of making a mistake, and literally traces its steps to find the food.
Hello.. At 2:09 on the video there is a small organism above the stentor? organism. It kind of moves liek a tumbleweed. Do you have any idea what it may be. Thanks :)
@RobertMOdell I remember asking myself the same question. It's not something we think of so much in our world, because we're much more complex, but we're basically the same as them. We are programmed to function in a specific manner. We've developed intelligence and a brain, but even we, on so many levels, behave automatically, as programmed, just like a single celled organism. Fascinating, yes? With enough programming and microscopic machines, even something like a human being can exist!
@chirrrs I think you'll find your cat has a central nervous systems... and a bacteria does not. Its also pretty easy to build a filter that detects and rejects based on shape, size and even colour with no consciousness whatsoever... I point you in the general direction of a peanut sorting machine!
@Queegzzz FACT: the DNA and RNA are observed to work closely together. Question: What seems more likely to you? Did they evolve into this co-oprtative relationship through the mechanism of natural selection, or were they "blinked" into existance by a majic man in the sky?
@smokeyflea I'm not convinced that it is a matter of programming. There is more going on here. Perhaps consciousness can be explained by the application of quantum mechanics into celular biology.
As for ownership and use, I'm pretty sure I recognize the voice as that of Jeremy Pickett-Heaps, a professor where I did my Ph.D. So...I doubt this poster has the copyright. Jeremy's youtube channel is here: ru-vid.com/show-UCH6cxhgl-S0Lk1nnaX8cMGA
