Lesson 10: Evolution

Natural selection and Artificial selection

Test Skeletons and evolution

T1D / T1E -> 14 dec

T1A -> 13 dec

-More practice and 1 lesson more for the owl pellets!

Charles Darwin

1809-1882

Species could change over time to become better adapted to their environment

This change is called evolution

Natural selection

Individuals that are best at surviving in their environment will produce more offspring and their DNA will therefore be more common in the next generation

Natural selection in Steps

1. More individuals will be born  that can survive 'struggle for existence'
   
2. Individuals with an advantage have a higher chance of surviving
   
3. The individuals that survive will have a higher chance to produce offspring so they will pass on their traits to their offspring
   

Artificial selection

Not nature is selecting but humans

Humans select the individuals they like best and this is different because it might not be due to best survival 

What is different between artificial selection and natural selection

1. Nothing, its basically the same
2. Natural selection has to do with survival, artificial selection not always
3. artificial selection is dependent on nature alone, natural selection is not.
4. Natural selection is done by humans, artificial selection not

Which of the following is NOT a component of the Theory of Evolution by natural selection?

1. competition for food and space
2. variation among species
3. inheritance of acquired characteristics
4. survival and reproduction

The dog breeds we have today were developed through:

1. natural selection
2. artificial selection (selective breeding)
3. sexual selection
4. acquired selection
