The tails of rats are amputated so their offspring will have no tails. Both parents’ tails are curved therefore the offspring is likely to be curved. I am knowledgeable because I read therefore my children will be knowledgeable. If I cut my hair then my children will have short hair.

3. I am knowledgeable because I read therefore my children will be knowledgeable. 4. If I cut my hair then my children will have short hair. Acquired characteristics which is untrue Acquired characteristics which is untrue

Do Now 1. In lab there were different size beans in which the “survivor” was either tweezers, spoons, or fork. What can you conclude about this? 2. What happens to the surviving specie if the remaining players die off from starvation? Tweezers are good to catch small beans while spoons are good for large beans. The survivor will pass off the “utensil gene” to their offspring.

Do Now 1. How did Darwin explain why there were 13 species of finches Do Now 1. How did Darwin explain why there were 13 species of finches? 2. What did he say of how one species of finches had turned into many?

Answer #1: Each species developed over time an adaptable beak for eating.

Some finches flew to other areas of the Galapagos Island and adapted to its environment (habitat, diet, etc). Answer #2:

Do Now and Notes In ___ selection, humans have an effect on the evolution of a species rather than letting nature choose the path of evolution. Four reasons why people use artificial selection: artificial a. Domesticating pets b. Farming animals and plants c. Making new drugs and

Do Now 1. Why is artificial selection used? a. Domesticated animals such as ___ b. Farming ___ and animals c. Pharmaceuticals (new ___ ) d. ___ engineering dogs crops drugs genetic

Pros and Cons Pros: Humans can manipulate organisms to benefit them New variations of organisms can be produced (example: cabbage, broccoli, cauliflower are all variations of the same plant) Cons: Selectively bred organisms are susceptible (at risk) to environmental changes and diseases Inbreeding can become a problem In animals artificial selection can cause health problems
