Whales have existed for millions of years. The discovery of many fossils with transitional features documents the transformation of whales from land animals to ocean dwellers. Another indication of whales' evolutionary heritage can be seen in the way they move. Beautifully illustrated, our poster shows the million of years of evolution that made this happen... Our non-paper poster material is waterproof and tear resistant. It is meant to last a lifetime and can even be used outside. This poster does not come with frame. Custom orders accepted.
