    Mollusks are simple animals, yet can be very smart.

Hank introduces us to the "simplest" of the animals, complexity-wise: beginning with sponges (whose very inclusion in the list as "animals" has been called into question because they are so simple) and finishing with the most complex molluscs, octopuses and squid. We differentiate them by the number of tissue layers they have, and by the complexity of those layers.

With a solid understanding of biology on the small scale under our belts, it's time for the long view - for the next twelve weeks, we'll be learning how the living things that we've studied interact with and influence each other and their environments. Life is powerful, and in order to understand how living systems work, you first have to understand how they originated, developed and diversified over the past 4.5 billion years of Earth's history. Hang on to your hats as Hank tells us the epic drama that is the history of life on Earth.

A sponge might not look like much, but these simple animals with no brain or ability to move have lived on Earth for hundreds of millions of years. They can hunt prey and spawn, and Jonathan demonstrates how in this fascinating segment about the biology of sponges! ********************************************************************** If you like Jonathan Bird's Blue World, join us on Facebook! https://www.facebook.com/BlueWorldTV Or Twitter! https://twitter.com/BlueWorld_TV On the Web: http://www.blueworldTV.com **********************************************************************

In which Hank and John Green teach you about life on Earth. They won't be giving advice on how life should be lived, because this is a history series. Instead, they'll teach you about the earliest forms of life on Earth, and some of the ways that they developed into the types of life we know, love, and sometimes don't love so much (I'm looking at you here, opossums). You'll learn about prokaryotes, eukaryotes, panspermia, reproduction, a little about DNA, and even a thing or two about trees. Maybe.
