18. Theory vs law
There are 5 main kinds of living organisms on our planet. Plants, fish-things that swim, humans, cattle, birds-things that fly
Within these 5 strands of life there are micro changes. We do not see a change between the categories only changes within the same categories.
We can see transformations within the categories. For example horses became bigger and faster in response to their environment- this allowed them to survive over time.
All species have changes that allow them to survive in their environment- where did this ability come from?

19. Law in science It is innate in nature
It can not be changed it is only observed
For example
Law of gravity
Law of gravity can be observed to occur over and over but it can not be changed in nature

20. Theory in science Is an explanation of why nature is the way it is
Theories can change
Evolution theory
It the best explanation at this time given the information we have discovered so far
More information then modifications to the theory can be made-we can change our theory as our knowledge grow

Evolution: Evidence and Theory
“The mechanisms of evolution are debated, not the fact that it has occurred and is occurring”

23. Charles Darwin was an English scientist.

24. Darwin traveled to the Galapagos Islands aboard the H. M. S

32. Darwin began to wonder if the animals living on different islands had once belonged to the same species.
These different species would have evolved from a common ancestor.

33. Charles Darwin
Proposed the theory that organisms evolve, or change over time, by natural selection.

34. For Darwin’s theory of evolution by natural selection to work, Earth would have to be very old and change slowly over time.
Around the same time, Hutton and Lyell proposed that geological forces shaped the Earth over Millions of years.

35. Evolution Evolution = change over time
Millions of years
Evolution = change over time
****It takes a long time to happen****
