continued… We moved on to the exhibit that Eric really wanted to see, Fossils. It covered 600-million years of history, and it was quite large. Eric was really interested and keenly read each and every display. Christi was ambivalent and half-heartedly read the displays that caught her attention. Keith was grossed out by skeletons and didn’t even want to be in the room. Keith constantly asked if we could leave yet and was frustrated when Eric kept saying no.
Since it was believed that life on Earth began in the ocean, it wasn’t surprising that the display on ocean creatures was large. Like in the Ocean Hall, they explained the evolution of many specific types of species. Scientists believed that in the early days of Earth, the world was very hot. Species evolved from simple organisms like algae and plankton into all kinds of complex species. The evolution helped them to adapt to their surroundings better, as well as to changes in their surroundings — either the species changed locations for one reason or another (ie to find food) or there was an environmental change (ie a salinity change). Some species left the water for land.
