What are two things that scientists learn from the fossils record?
The fossil record provides evidence about the history of life and past environment on earth. The fossil record also shows that different groups of organism have changed over time.
What methods do scientists use to obtain data for phylogenetic trees?
Scientists use the fossil record and structural and molecular comparisons to construct phylogenetic trees. This answer came straight from my freshman Biology book.
Why did scientists use trilobites as index fossils?
Scientists used trilobites as index fossils because they were abundant, had a wide distribution, and had a relatively short existence in the fossil record. This made them useful for correlating rock layers from different locations and determining the relative ages of the rocks.
To be useful as an index fossil fuel spices must have existed for how long?
To be useful as an index fossil fuel, spices must have existed for about 1000 years.
How many years ago were protists first found in the fossil record?
Protists were first found in the fossil record around 2.1 billion years ago.
What do scientists use the fossil record for?
Recording fossils No.
What do scientists use to study macro evolution?
The fossil record
What do scientists often use to study macroevolution?
The fossil record
What does the lack of fossil record for some of the Earths history mean to scientists?
that the fossil are oder then what we think
How did Charles Darwin view the fossil record?
useful support for his theory
What two major developments helped scientists explain the fossil record?
The theory of evolution by natural selection, proposed by Charles Darwin, helped scientists understand the gradual change of species over time recorded in the fossil record. Additionally, advances in radiometric dating techniques provided scientists with the ability to determine the age of fossils more accurately, allowing for a deeper understanding of the timeline of life on Earth.
What tool can help scientists to determine ancient species became extinct?
fossil record
Why are species missing from the fossil record?
because sometimes the scientists don't find the fossils
What are two things that scientists learn from the fossils record?

What do scientists today rely on primarily to determine evoluutionary history?
Scientists rely primarily on the fossil record to determine evolutionary history. Another way of determination is examining the genetic record.
What is the chronological collection of life's remains found in layers of rock?
The answer is the fossil record :D
Scientists used major changes in life forms in the fossil record to form the geologic time scale?
yes
