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 is the chronological collection of life's remains found in layers of rock?
The answer is the fossil record :D
Do scientists use major changes in life forms in the fossil record to form the geologic time scale?
Yes, scientists use major changes in life forms in the fossil record to help identify and define different periods of time in the geologic time scale. These changes in life forms, known as biostratigraphy, provide important clues for correlating and dating rock layers and understanding the evolution of life on Earth over time.
All fossils that scientists have collected create the?
Fossil record..... which is all of the fossils collected over mil lions over years also..they havent ever started it over
What do scientists use to determine a fossil's relative age?
Carbon14 dating (isotopic dating)
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
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.
How scientists estimate the age in years of a fossil?
Scientists can use carbon dating to determine the age of a fossil.

Why are species missing from the fossil record?
because sometimes the scientists don't find the fossils
What tool can help scientists to determine ancient species became extinct?
fossil record
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 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
