Changes to our Earth NB Page 5 Earth’s Story – For 1000s of years humans have wondered about Earth’s history. – Two main view points: – 1. The Earth was shaped suddenly – 2. The Earth was shaped slowly over billions of years. – This argument is known as catastrophism vs uniformitarianism. NB Page 5 Catastrophism – Catastrophism- principle that states all geologic change occurs suddenly – Evidence: Biblical floods, asteroid strikes and other catastrophes created mountains, canyons, and seas. NB Page 5 Examples of Catastrophism – Earthquakes – Tsunamis – Volcanic Eruptions NB Page 5 Uniformitarianism – Uniformitarianism- principle that states the same geologic processes shaping Earth today have been working throughout Earth’s history. – Evidence: Weathering, erosion and other geologic processes happen slowly. Therefore the Earth must have been shaped slowly. NB Page 5 Examples of Uniformitarianism – weathering- the breakdown of rock – erosion- the movement of weathered rock – deposition- the dropping off of weathered rock **** these all happen in many ways… more on this later NB Page 5 Real Life – Earth has been shaped by a combination of catastrophism & uniformitarianism. – Most geologic change is slow & gradual. – But catastrophes have contributed to shaping Earth.

Fossil Record: - - - Summary: NB Pg: 8-9 EQ: What can a fossil tell you about life long ago? Warm Up- What is Evolution? What does it mean to evolve over time? What proof would you need to know this has been happening for all of time? Create and write a story to explain this image. Be prepared to share it out Overview of the Geology 1. Geology is the science of the lithosphere, including the Earth's physical structure and substance, its history, and the processes. 2. Geology provides tools to determine the relative and absolute ages of rocks found in a given location. 3. Geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. 4. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. FOSSILS AND ANCIENT LIFE • Fossils provide information about extinct species—species that have died out. • Fossils can be large and perfectly preserved as an entire animal. They can also be as small as bacteria, developing embryos, or pollen grains. • Many fossils are just fragments of an organism—teeth, pieces of a jawbone, or bits of leaf. • Sometimes an organism leaves only trace fossils—casts of footprints, burrows, tracks, or even droppings. • Most fossils are preserved in sedimentary rocks, some are preserved in other ways, such as in amber. What can fossils reveal? 1. What part of the animal has been preserved? 2. What can paleontologists infer from fossils? Relative Dating 1. Which index fossil is found in all three locations? 2. Using the index fossils shown, determine which layers are “missing” from each location. Overview of the Fossil Record 1. A rich record of thousands of fossils show clear evolutionary paths. 2. These include fossils of extinct ancestral species “transitional” fossils showing crucial changes in form, such as water-based animals evolving to live on land; and many forms of human ancestral species. 3. Fossils found in the bottom layers of the Earth's sediment are the oldest. 4. Organisms are found 5. The Fossil Record can in the following order: account for many - modern organisms apparent gaps - mammals because organisms - reptiles need to die under the - amphibians right conditions to be - fishes preserved and - invertebrates protected from - Trilobites scavengers that might - simple multicell- eat them. ular organisms - eukaryotes - prokaryotes Exit ticket: With a different color, write down any additions/changes to your story. Warm-Up What is happening in this image? Spend 3 minutes discussing this with your table group. Be prepared to share out your ideas Video: Fossils: Rocking the Earth NB pg. 10 1. What are some things that can be fossilized? 2. How does the fossil record provide evidence for evolution? Where did life start? How do you know? Things to think about… What does all life have in common? Where does everything come from? What are a few examples of the last organisms to evolve? How did you know? What do the birds, mammals, amphibians, They all come from… and reptiles all have in common? This is what we call a Common Ancestor POGIL: Evidence for Evolution In your own words… • What is a Common Ancestor? • Common Ancestor: an ancestor that two or more descendants have in common • Common Decent: Phylogenetic Trees More complex Tree of Life Homologous and Analagous Structure Activity • Give students pictures of different animals • Categorize them, they get to decide…animals that fly, jump, (analgous features) Homologous Structures (Write and Draw) Homologous structures have similar forms and develop from the same embryonic tissues. They provide strong evidence that organisms have descended, with modifications, from common ancestors. Some homologous structures no longer serve important functions in descendants. Overview of Homologous Structures 4. Homologous structures, such as the fins of whales and the hands of monkeys, demonstrate that while a species may use structures for different purposes, the species shared a common ancestor. 5. The natural world is full of examples of homologous structures, which the theory of natural selection predicts should be the case What is a fossil?.
