Artificial Selection

h. Individual with weaker traits are protected so they can survive
i. When a lizard lays its eggs, all the baby lizards are slightly different colors and different sizes
20. Darwin’s theory of Natural Selection is made of 4 main parts; overproduction, variation, competition, selection. In the
boxes provided, make a sketch that shows each of these ideas.
Overproduction
Competition
Variation
Selection
Determine if the following statements are true or false. If false, change the underlined work to make it
correct.
______________21. The ability of an individual to survive and reproduce in its environment is its artificial selection
______________22. When more babies are born than could possibly survive is an example of variation
______________23. Fossils are the remains of ancient creatures Darwin used to develop his ideas for natural selection
______________24. For natural selections, bad traits build in the population over many generations
______________25. An adaptation is an inherited trait that increases a creatures chances for survival
