What can changes in the fossils of a single organism over time reveal?
how the species evolved
When is a valid conclusion a scientist can make about the fossils?
A valid conclusion a scientist can make about fossils is that they provide evidence of past life forms and their environments. By studying the physical characteristics and locations of fossils, scientists can infer evolutionary relationships, extinction events, and changes in Earth's climate over time. Additionally, the stratigraphic context of fossils can reveal the relative ages of different species, contributing to our understanding of the history of life on Earth.
What can a scientist learn about evolution when comparing different fossils in rock layers?
By comparing different fossils found in various rock layers, scientists can infer the chronological order of species and their evolutionary relationships. This stratigraphic analysis helps identify patterns of species emergence, extinction, and morphological changes over time, providing insights into how organisms adapted to their environments. Additionally, it allows researchers to trace the lineage of species and understand the impact of environmental changes on evolution. Overall, such comparisons reveal the dynamic history of life on Earth.
How do fossils provide evidence that species alive today have evolved from simpler organisms?
Fossils provide evidence of evolution by showing a record of past life forms, demonstrating the gradual changes in species over time. By examining the fossil record, scientists can trace the lineage of modern species back to simpler, ancestral forms. Transitional fossils, which exhibit characteristics of both older and newer species, further support the idea of evolution by showing the gradual changes that occurred over generations. Overall, fossils provide tangible evidence of the process of evolution and the interconnectedness of all living organisms.
What idea of Darwin's based ion fossils and the modern organisms he found basically says that genetic changes inherited by later generations?
Darwin's idea related to fossils and modern organisms is encapsulated in the theory of evolution by natural selection. He proposed that species evolve over time through genetic changes that are inherited by subsequent generations. Fossils provide evidence of these gradual changes, showing a progression from ancient species to their modern descendants, highlighting the connection and adaptation of organisms over time. This process leads to the diversity of life we observe today.

What can fossils tell us about the movement of the plates in the past?
Fossils can provide information on the distribution of ancient species across different continents, which helps in reconstructing past continental positions. By comparing the similarities and differences in fossil species found on separate continents, scientists can infer the movement and interaction of tectonic plates in the past. Fossils can also reveal how environmental changes associated with plate movements influenced the evolution and distribution of species over time.
How are fossils an example of evolution?
Fossils show certain species underwent small changes over a period of years the rock in which the fossil is encased dates the fossil and so they can put them in order to show the progression of the physical changes

How do fossils that form in different rock layers provide evidence of evolution?
Fossils' existence confirms that species are not fixed but can evolve into other species over time
Which is one piece of information that fossils in samples from Earth’s crust reveal about Earth’s history?
Fossils in Earth's crust can reveal information about past environments, climates, and the evolution of life on Earth. They can also provide insights into the age of rocks and the geological processes that have shaped the Earth over time.
If species didn't change what type of fossils would we see?
If there was no change in species over time, then all fossils of that species would be identical.

What can scientists learn about fossils?
Scientists can learn about ancient life forms, their environments, and evolutionary processes through the study of fossils. Fossils provide insights into the morphology, behavior, and ecology of organisms that lived millions of years ago. By analyzing fossilized remains, scientists can reconstruct past ecosystems, understand climate changes, and trace the lineage and extinction of species over time. Additionally, fossils can reveal information about the geographical distribution of organisms and help in dating geological layers.
What type of evidence acts as a record of changes in organisms over time and indicates major changes in earths surface and climate?
Fossils serve as evidence of changes in organisms over time and reveal major changes in the Earth's surface and climate. By studying the types of fossils found in different rock layers, scientists can understand how life has evolved and how the environment has changed over millions of years. This field of study is known as paleontology.
What can scientists learn by examining fossils?
Scientists can learn about the morphology, behavior, and evolution of ancient organisms by examining fossils. Fossils provide insights into past environments and climate conditions, helping to reconstruct ecosystems and understand how life has changed over time. Additionally, studying the distribution of fossils can reveal information about continental drift and extinction events. Overall, fossils serve as a crucial record of biological history and Earth's changes over millions of years.
