Telle how many type of evidence,to find we have common ancestor.
Answers
Answer:
Explanation:
Evidence of common descent of living organisms has been discovered by scientists researching in a variety of disciplines over many decades, demonstrating that all life on Earth comes from a single ancestor. This forms an important part of the evidence on which evolutionary theory rests, demonstrates that evolution does occur, and illustrates the processes that created Earth's biodiversity. It supports the modern evolutionary synthesis—the current scientific theory that explains how and why life changes over time. Evolutionary biologists document evidence of common descent, all the way back to the last universal common ancestor, by developing testable predictions, testing hypotheses, and constructing theories that illustrate and describe its causes.
Answer:
Evidences for evolution: anatomy, molecular biology, biogeography, fossils, & direct observation.
Explanation :
Evidence for evolution comes from many different areas of biology:
★Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
★Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.
★Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
★Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.
★Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).
