Examining the Fossil Record. Fossils are traces of organisms that lived in the past. When fossils are found, they are analyzed to determine the age of the fossil. The absolute age of the fossil can be determined though radiometric dating and determining the layer of rock in which the fossil was found. Older layers are found deeper within the earth than newer layers. The age and morphologies appearances of fossils can be used to place fossils in sequences that often show patterns of changes that have occurred over time. This relationship can be depicted in an evolutionary tree, also known as a phylogenetic tree. There are two major hypotheses on how evolution takes place: gradualism and punctuated equlibrium. Gradualism suggest that organisms evolve through a process of slow and constant change. For instance, an organism that shows a fossil record of gradually increased size in small steps, or an organism that shows a gradual loss of a structure.

This activity consists of 2 parts created by different entities. The simulation has instructions on the left side of the screen with a bar that can be scrolled forward as you proceed. The icons are interactive at the bottom of the page: a nail with a tag and a magnifying glass, the computer, a chisel and a specimen collection box.
The dig site number is displayed at the top so students can keep track of which site they are using. The worksheet provides the background, procedure and data tables from each dig site organized in a way that the data can be easily transferred and analyzed. MS-ESS Analyze and interpret data on the distribution of fossils and rocks, continental shapes, and seafloor structures to provide evidence of the past plate motions. Clarification Statement: Examples of data include similarities of rock and fossil types on different continents, the shapes of the continents including continental shelves , and the locations of ocean structures such as ridges, fracture zones, and trenches.
Assessment Boundary: Paleomagnetic anomalies in oceanic and continental crust are not assessed. This resource appears to be designed to build towards this performance expectation, though the resource developer has not explicitly stated so. Comments about Including the Performance Expectation In the dig site simulation the students start immediately interpreting data and finding evidence on the distribution of fossils and rocks. The worksheet has labeled data tables used to organize and interpret the findings of the dig site simulation.

How Do Scientists Date Fossils. including the age and origin of life, the timing of mass extinctions and the record of human evolution. The first big challenge is to find the right kind of rocks to collect for laboratory analysis.
Around the time that On the Origin of Species was published, Lord Kelvin authoritatively stated that the Earth was between 20 and million years old, a range still quoted today by many who deny evolution. As it was difficult to conceive of life’s diversity arising via natural selection and speciation in so short a span, the apparent young Earth formed a serious barrier to the plausibility of evolution’s capacity to generate the tree of life.
Huxley famously attacked Kelvin, saying that his calculations appeared accurate due to their internal precision, but were based on faulty underlying assumptions about the nature of physics . Garniss Curtis was born in San Rafael, California in This was just 15 years after Ernest Rutherford, famous for discovering the nucleus of the atom and the existence of the phenomenon of radioactive half-life, walked into a dimly lit room to announce a new date for the age of the earth: 1.
Lord Kelvin, the venerable alpha of Earth-age estimates, was in attendance. To my relief, Kelvin fell fast asleep, but as I came to the important point, I saw the old bird sit up, open an eye, and cock a baleful glance at me!
