The creation and destruction of species Proof of evolution in fossil records The slow change of old species. Works with all species on Earth.
Microevolution on a small scale. Microevolution can happen in a life time. Example, H.I.V. evolves daily from mutations. It can be seen in fossils.
Microevolution can be found in fossils. Microevolution can happen in few generations. Small changes over length of time. Example, the size of the sparrow.
Is large change over a long time. Changes one species into another one. Takes a very long time to happen. Example, monkeys to humans.
Macroevolution can be seen in fossils. Considered new species when it can’t breed. All animals have one common ancestor. Example, the lizard to the snake.
Evolution takes a very long time. Has been going on for about 3.8 billion years. 95% of all spices are extinct. All species have a common ancestor.

Chapter 19.2 (Pgs ): Patterns and Processes of Evolution
1 Theory of Evolution Today Supporting Evidence. 2 Homologous Structures.
We think it was between billion years ago Why can we not be certain how life on earth began?
Evidence for Evolution
Aim: How did Earth evolve to support life? How did life evolve? Do Now: Do you think that organisms are more complex now, or were more complex in the past?
PATTERNS OF EVOLUTION Chapter 17-4
Recap on Evolution. What is the Theory of Evolution? Evolution is defined as change over time. One of the earliest theories of evolution was put forward.
1 2 The Earth is this old 3 What is a 4 billion years?
The Theory of Evolution. Evolution a gradual change in the genetic material of a population. (Population = all the animals of the same species living.
INTRODUCTION TO EVOLUTION
1 Organisms Change Over Time. Darwin proposed that organisms descended from common ancestors Idea that organisms change with time, diverging from.
LINES OF EVIDENCE FOR EVOLUTION. Fossils and Rock Layers Earth is OLD!!! Earth has CHANGED A LOT over its 4.5 billion year history!!! Many organisms are.
Evidence of Evolution. Evolution The process by which life has changed over time. Macroevolution Microevolution.
Unit 5 Evolution. What is Evolution? Evolution: Microevolution Change in a population’s genetic structure over time Change in: alleles/genotype.
Human Origins By: Molly McGarry. 3 Hypo these of Human Origins Myth~ Greek Mythology Zeus creates humans Myth~ Religious Bible- Adam and Eve Theory~
1. Natural Selection Driving force for evolution During the struggle for resources, strongest survive & reproduce Idea that at least some of the differences.
Genes and Variation What if so many changes, population can no longer breed with the original population? New species Speciation DNA mutation Beneficial.
Biological Diversity Macroevolution: Ch. 15. Review What is microevolution? Evolution on the smallest scale –Generation to generation change in the frequencies.
Chapter 5 Evolution of Biodiversity. Earth is home to a tremendous diversity of species What are the three levels of diversity? Define them! How many.
Are birds more closely related to reptiles or mammals?
