1. Select an animal or plant that you are familiar with that is living now. Describe several characteristics of this present day animal or plant.

2. Take this animal or plant and make small changes over long periods of time (thousands/millions of years) in 10 steps - the changes could be caused by factors such as pathogens, environmental, competition, climate, etc. Work as a group. Indicate the factor and what change it caused in the animal or plant at each step. Make small changes.

3. Clearly describe the changes in the original animal or plant. Remember that small changes are made over long periods of time. Show gradual change at each step. Remember to include the cause for the change.

4. This is not about the current known fossil history of an animal or plant, such as the evolutionary history of the modern horse. It is about taking the modern horse and changing it into something that has never been seen on earth - or at least we think it has never been seen before. Use your imagination.
