MCR-1 GENE ISOLATEDMCR-1 gene isolated from human for first time in Brazil.
In this two-part activity, which uses discovery and an inquiry approach, the participants will be given cartoon drawings representing significant events in the history of the Earth and asked to place them on a timeline made of colored ribbon. Then they mathematically relate the geologic time scale to a yearly calendar. After the calculations, they return to the timeline to reassess the placement of the events.
Earth history, microbial evolution, historical events, time scales.
