Question

fill in the blanks with the following words: bones, relative, fossil, shells, older. the ____ record is the collection of all fossils that have been discovered, along with their __ ages. fossils can include remains like __ or __, and also things like footprints or impressions. as you go deeper in rock layers, generally the organisms are ____ in age. questions to answer what are two ways fossils help scientists learn about organisms that lived long ago? how does the fossil record show changes in organism complexity and diversity over time? what is one example the video gives of a major transition in life’s history? what is extinction, and how is it shown in the fossil record?

Explanation:

The fossil record is the collection of all fossils with their relative ages. Fossils can be remains like bones or shells. Deeper rock - layers generally contain older organisms. Fossils help scientists learn about past organisms by providing information on their structure (from remains like bones) and their environment (from associated fossils and rock layers). The fossil record shows changes in organism complexity and diversity over time as more complex and diverse forms tend to appear in younger rock - layers. A major transition example could be the evolution of land - dwelling organisms from aquatic ones. Extinction is the disappearance of a species, shown in the fossil record when a species' fossils stop appearing in younger rock - layers.
