How do scientists know that organisms have changed over time?
Scientists use evidence from the fossil record, comparative anatomy, DNA analysis, and observations of natural selection to understand how organisms have changed over time. By studying these pieces of evidence, scientists can track the gradual changes in species over generations, providing strong support for the theory of evolution.
How does adaptation prove the study of evolution?
Adaptation is the process by which organisms become better suited to their environment over time. This process demonstrates the way in which organisms evolve to survive and reproduce in their specific surroundings. By studying how organisms adapt to changes in their environment, scientists can gather evidence to support the theory of evolution.
How are similarities in macromolecules among organisms used as evidence to support evolution?
Similarities in macromolecules, such as DNA and proteins, among different organisms can be used as evidence to support evolution because these similarities can be used to construct phylogenetic trees that show how different species are related to each other. The more similar the macromolecules are between two organisms, the more closely related they are thought to be, indicating a shared evolutionary history. This provides molecular evidence that supports the idea of common ancestry and gradual evolution over time.
What provides evidence for evolution?
The fossil record, although not complete, provides a lot of evidence. There is also supporting evidence from geological studies, and the extensive human and nonhuman genome studies that are currently being done.
How is DNA utilized as evidence to support the theory of evolution?
DNA is used as evidence to support the theory of evolution by comparing the genetic similarities and differences between different species. By analyzing the DNA sequences of organisms, scientists can trace evolutionary relationships and determine how species have evolved over time. This genetic evidence provides strong support for the idea that all living things are related and have evolved from a common ancestor.

Does alcoholism skip generations?
No. There is no scientific evidence to support this theory.
What evidence could support that organisms under microscope are living organisms?
Living organisms:ReproduceGrowDieAre made of carbon organized by DNAFeedAvoid painful stimulatusMicroorganisms do all of these things
How are fossils a piece of evidence to support evolution?
Fossils show the progression of ancient organisms. By comparing older fossils with more recent fossils, we can see how older ones are related in body structure to newer ones, supporting the idea that new generations evolve from older ones.
How did the study of organisms on islands help support Darwin's ideas?
It Gave evidence and the fossil organisms on the bottom or older layers were more primitive than those in upper or newer layers.
How does adaptation prove the study of evolution?
Adaptation is the process by which organisms become better suited to their environment over time. This process demonstrates the way in which organisms evolve to survive and reproduce in their specific surroundings. By studying how organisms adapt to changes in their environment, scientists can gather evidence to support the theory of evolution.
What does corroborate mean?
Corroborate means to strengthen or support with evidence.
What is the meaning of the phrase Growth is an evidence of life?
Organisms grow because they are alive. Conversely, organisms are alive because they grow - they grow, adapt, and change to survive in their environment. This phrase is in support of the theory of evolution.

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.
