Their arms became wings and they (mostly) took to the skies. Birds are evolved theropod dinosaurs (T.Rex was one too!). True, of course. One look at the iridescent grackles at my bird feeder tells me what the fiercest dinos might have been like, only much larger. Still, if they larger ones had survived, and kept the mammals from filling their niches, I can imagine some evolving in a sentient direction. /Mr Lynn Definitely. It's probably just evolutionary chance that a mammal happened upon the ecological niche that favored intellect. Could have been a fish, bird, reptile, whatever. Time and DNA replication together provide the mechanism for creating anything that will give an advantage.

There is a lot of evidence that early hom o sapiens didn't do any of those things any better than modern bonobos. There is no evidence that bonobos or any other creature possesses the characteristics or capabilities I mentioned. The appearance of homo sapiens in the fossil record does not appear to coincide with the huge intellectual leap that begat us civilization. That leap came fairly late in the reign of homo sapiens. Agreed. On the other hand, the things I noted along with certain other anatomical changes (e.g. laryngeal and lingual anatomy, the MYH16 gene mutation hypothesis) likely preceded and may have been necessary precursors to the leap in intelligence in h o m o sapiens. Re: Planet Earth without humans - Carnos Jax - 08-26-2014 As noted, birds are dinosaurs. Dinosaurs and mammals were parallel evolutionary paths that stemmed from fishes--->amphibians--->reptiles. One thing that each line had in general over its predecessor line is intelligence. So it's fair to say Dinos and mammals were trending equally in this area (no surprise that some bird species are number 2 on the intelligence list below humans). Going further, there were members of the theropod line of dinosaurs (of which birds are) that were speculated to eventually develop a humanoid form. Only thing is that Dinosaurs had dominated for 250 million years...you'd think they'd have made something of themselves (pure whimsical speculation of course on my part, as evolution is not always so straightforward in its timing, etc.). Re: Planet Earth without humans - Carnos Jax - 08-26-2014 P.S. - Its easy to forget that what we've talked about are the vertebrates. Cephalopods (octopus, squid) humble me with the intelligence they show in their short lives. I wonder what they would amount to if they had longer lives.

For all we know, the whales and dolphins have culture, as much as we or the chimps do. Who's to know whether the cuttlefish or bees or ants don't also? It's typical of the human mindset to assume that life or civilization must take the same form as yours.

It's typical of the human mindset to assume that life or civilization must take the same form as yours. It depends how you define 'civilization'. Space-time asked, "what species would be most likely to develop a civilization as advanced as ours?" By 'advanced' presumably he means 'technologically advanced'. That would be hard to do under the sea, without fire, though alternative means of manipulating chemicals and materials can certainly be imagined. There was a story many decades ago in which the victim of a sunken ship is rescued by intelligent beings in the ocean depths, cephalopods I assume. I can't recollect the title and author at the moment, though with a little digging I could probably find it. Humans, more than any other animals, are what Alfred Korzybski called 'time-binders'. Through the medium of language, they pass increasingly complex information down from generation to generation, without genetic encoding. No other known creatures can do this to anything close to the human extent. /Mr Lynn Re: Planet Earth without humans - pdq - 08-26-2014 Scientific American wrote: Dinosauroids! ![]() Re: Planet Earth without humans - decay - 08-27-2014 I can also spot a Kirby piece very quickly |
