NATURAL SELECTION SIMULATION (“STICK-BIRD”)
INTRODUCTION
Within a hypothetical population of “worms” (toothpick) that inhabit a predominantly green-coloured environment (green grass), there are four colour of variations; red, blue, cream and green. The worms are food for a predator known as a “stick-bird” (students). This experiment is designed to let students observe the effects of the theory of evolution by natural selection. Natural selection is an explaination of how evolution could have occurred which was proposed by Charles Darwin. The Darwin’s theory outlines that characteristics favorable to the reproduction and survival of organisms in their environment will be selected for, over time, new species will appear in response to environmental changes.

To plan a first-hand investigation to model natural selection with an …show more content…
How can this be explained?
Most of the animals are able to remain their constant population as the rate of delivery will balance the rate of motality.
2) Were some animals better adapted for survival than others? Support your answer with evidence.
Yes. For example, the black peppered moths are better adapted for survival compare to the white peppered moth. This is because when industrial revolution happened in England, the environment become black and the black moth can be well camouflaged. In the hand, the white moths will be easily catch by its predators as they are easier to see compared to the black moths.
3) Does natural selection appear to have an impact on the population? Explain.
Yes. The environment will select a favour for some variations over the others. The fittest will survive and reproduce more causing a higher population and pass their characteristic to the next generation.
4) Did some animals appear to be better adapted for survival in some specific areas of field? Write your answer as a
