This week in science, we learnt about evolution and matural selection in iguanas. The iguana originated in the color green and was a land mammal. Then,somehow the iguana's decendents got to the galapognos Islands. then they started sto evollve. The iguana was unable to live very much. Therefore, they evolved very slowly. The iguana feirst survived on some vegetaion that was left there on the island. Then they reproduced. Then the iguanas died from natural process and the children feasted on the parent's bodies. Then like that, the children reproduced and the th eparents died to let the chi;ldren eat their bodies. Like that, the iguana populaiton increased on the galapogonose islands. Then the iguanas had a genetic mutation. This gave them more possiblities of survining at that location. exp...(camoflagueing into rocks,gills to survive underwater.) And so, the iguanas survived the galapognose. Then on Friday, we had a quiz on this.
