How Will Animals Look 250 Million Years From Now?

angkor writes "'How will Earth look 5 million, 100 million, even 200 million years from now?' Fantasic and fun speculation from Animal Planet. It's the work of Dougal Adams, who started this idea years ago in the out-of-print After Man: A Zoology of the Future."

Frankly, I didn't like it

First of all, let me state I'm no scientist. But some stuff just doesn't seem reasonable:

• FLISH (for FLying fISH) - Does it make much sense that an animal that cannot generate its own heat would spend an enourmous amount of calories flying? Also, is there a fish that can fly like a bird these days or any indication in that sense? The contrary is pretty common (penguins, et al).
  
  
• Giant Squid roaming the forests - Owhhh, C'mon! What possible advantage is there in it? They can get all the food they need, without the hassle of vertebrae, in the ocean.
  
  
• Sharks with flashing colors - This one was just too bad! Why would a shark need flashing things on the side of their bodies? According to the program, to "guide the other sharks and hunt in packs". C'mon... We all know light gets filtered rather rapidly by water. Wouldn't sound be a better choice?
  
  
• Chrome Spiders herding the last mammal on earth - Yes, you heard it right. BTW, what's the point in a animal being silver chrome in color? To shine the sunlight and attract the predators?
  

I also disliked the concept that most animals will get bigger. That seems contrary to what we've observed in the last million years. Animals like Sharks and Alligators have survived millenia without many changes. What makes one think the radical changes proposed in the program would occur?

Funny thing is that I had my nephew (11 years old) watching the program with me. He laughed most of the time and thought the ideas were mostly ludicrous. And see, he's 11...

I was able to find it at a local thrift shop

It is quite hard to get hold of but I run a very small online book business in the UK, PristineBooks.com, and have 20 new copies selling for $27 or £17 or 27 Euros payable via PayPal and including free shipping to anywhere in the world. Next day delivery in the UK, three days to mainland Europe and around one week to the US, Asia and Australia.

Apologies for the shameless plug but I guessed that the out-of-print status of this book might cause a lot of frustration to anyone who finds this discussion interesting.

Anyone who's interesting can contact me via the PristineBooks.com site, cheers.

Don't they watch today's nature documentaries?

[geekotourist]

Because if they'd seen a few more before producing this show they could have made it much better. I was fast forwarding far too many times- it was slow. Now that Tivo believes I am Charles Darwin I have a near infinite supply of "death in the desert- a viper's story" type shows (which I *do* watch, so it's not a bad thing). What a typical nature show has, which the Future is Wild didn't, include:

• A focus. While they couldn't give us a mother and cubs, they could've given us the evolutionary equivalent. Take a couple of classes or orders and get us to care what happens to them over then next 200 million years. Introduce the squids early on. The only continuity TFIW had was "location of former cities"
• Drama- rather than suddenly show the last mammal, they should've shown 100 million years of decreasing diversity.
• Digressions. TFIW had few animals per time zone. If TFIW didn't have the computational budget to animate more they at least could have had more still shots. Documentaries tend to be filled with side loops, constantly showing local diversity- while the predator waits, we take five minutes to check out a cute symbiotic relationship, or a flock of colorful birds, or the prey's prey, or a dung beetle (which also is part of my next point...)
• Humor. Let's see some baby spiders falling off the web before going into the extinction of mammals next time.

A few random points relating to other threads in the comments:

• Flying fish- yes, they do exist, flapping their tiny pectoral fins: check out some of the Amazonian Hatchetfish species.
• The unlikeliness of X (giant land squid, silver spiders, etc): who'd have predicted what Pikaia-like creatures could lead to over the next 500 million years
• the diversity of life over the past 500 million years: spend a few hours exploring the Tree of Life Project: after that, none of TFIW speculations seem too weird (although they made some physiological mistakes- as pointed out by others, the giant tortoises's legs don't make sense)
• Extinct mammals: well, out of all of these all we have left are the birds.
• Missing signs of humans: I've seen estimates (can't find them right away- one was in Sci-Am I think) that suggest most large-scale signs of humans (buildings, satellites, canals) would be gone within 500,000 years. Even the longest-lasting signs (large concentrations of radioactive elements, space probes, AOL CDs) won't last more than 100-200 million years given subduction, etc).
