II. Skimming:
1. Fill in the following blanks according to the passage:
Scientist Research/experiment Result
Charles Darwin 1 2
Gregor Mendel 3 4
Gote Turesson 5 6
Key:
1. The wildlife of Galapagos, many varieties of garden roses
2. There were differences between the species of the different islands’yet all showed a clear relationship with those of America’ differences in habitat could lead to different species in birds as well as in plants.
3. Flowers and peas
4. Many characteristics were passed on from one generation to the next, without influence by the environment. His research gave birth to the science of genetics
5. A wild plant found on the Swedish west coast
6. Found evidence for the existence of stable varieties within species in nature. He showed that differences between plants of one species occurred as a result of the environmental conditions in their habitat.
