Explain how scientists use patterns in fossil records and in embryo development as evidence for evolution

Answer 1

Scientists use patterns in fossil records and in embryo development as evidence for evolution by comparing the similarities and differences between different species over time. Fossil records show a progression of life forms from simple to more complex organisms, and the patterns seen in these records provide evidence for the gradual evolution of species over millions of years.

Additionally, scientists analyze the similarities and differences in the development of embryos of different species to understand their evolutionary relationships. For example, the early stages of embryonic development often show similarities between different species, indicating a common ancestry.

By examining these patterns in fossil records and embryo development, scientists can trace the evolutionary history of different species and build a better understanding of how life on Earth has changed and diversified over time. This evidence supports the theory of evolution by natural selection, which explains how species evolve and adapt to their environments.
