Life has evolved into a multitude of sizes. Over the course of three billion years, life has taken on many forms – from an .02-micrometer-long bacteria to the 110-foot-long blue whale. Scientists are learning how the struggle for survival has led some animals to become small and others to get huge.
Understanding the evolution of size tells us why giant dinosaurs went extinct while the first tiny mammals thrived; gives us answers to why mammoths evolved into pygmies when restricted to islands; and why carnivorous mammals have never grown to weigh more than a ton. Whether it’s the speed of movement or population numbers, the biological world revolves–and “evolves”–around size.
It’s a tough, violent, and lethal world out there, and it’s been that way since the dawn of time. Roughly 99 percent of all species have become extinct. What enabled that other one percent to survive the cutthroat competition?
Their ability to…. EVOLVE.
Through a stunning combination of dramatizations, computer animations, live action nature footage and lab work; discover the biological and behavioural innovations that have kept us all on this Earth!

Funny how people always think that bigger is better. Which is usually not the case when it comes to how things work out in the natural world.
when's the next one ?!
yup, i agree with Eferhilda
Added to the list. Watched some more last night, and noticed that a lot of the "How the Universe Works" that you originally linked us to was taken down. Glad I saw it when I did!
Megafauna FTW! I would also like a 2 foot tall horse though.
Cool stuff, these series are pretty interesting.
Awesome, I love watching these.
my head still try's to wrap around just how long these things must have taken to evolve
i love the evolve series.
