The entire "Future is Wild" miniseries can be ordered online. A friend got it for me for my birthday. I found the entire series rather enjoyable. I imagine a lot of it might have gone a little like this in the planning stages:
PRODUCER: Hey, our SFX guys came up with this, so I'm asking you science guys if it might be possible, I mean, it'll look soooo cool..!
SCIENTIFIC ADVISOR: Well, I suppose, under extremely specific circumstances that nobody can completely predict with any real chance at accuracy... if certain factors don't come into play while others do... if these other species go extinct... umm... I guess, uh, maybe it might turn out like that in the time period you've come up with... although really this is just specula-
PRODUCER: GREAT! I'll call the SFX guys and tell them to get rolling on the CGI! It's the big thing with the kids these days! And you'll tell how these critters got that way, right!?
S.A. : Well, I guess-
PRODUCER: The ratings are gonna be great! Don't like this name, though. Squimps. Squorillas... naw, not cute enough... how about... SQUIBBONS!!
S.A.: Great. Yeah. Squibbons. Just make sure that on the check my name is spelled correctly this time...
Personally, I thought where they take bat evolution in so short a time seems morphologically unsound. For creatures that have barely changed in about 55-60 million years (I speak of insectivores - macrochiroptera came along considerably later), they seem to evolve a helluva lot in brand new ways over the next twenty million. What's with the long goose-like necks and disproportionately tiny heads? Vampiric behavior makes some sense, especially feeding on future descendants of modern avian life, but to live this way, modern vampires must live in regions where there are huge amounts of easily-attainable prey (livestock, poultry). Vampires were relatively rare before Europeans arrived with their style of agriculture. This program shows them living in a frigid desert region where their prey seem to stand a good chance of escape just by burrowing. This is all provided that we haven't killed them all off long before this, of course.
I did really dig the Rainbow Squid, however.
There have been a lot of really good, well-researched shows using cutting-edge SFX recently. In particular, I look forward to what Nik will be bringing us soon, but much as I like watching my copy of "The Future is Wild", that miniseries is purely to be taken as entertainment.
