Detailed explanation-1: -Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species’ relatedness.
Detailed explanation-2: -Comparing DNA Today, scientists can compare their DNA. Similar DNA sequences are the strongest evidence for evolution from a common ancestor.
Detailed explanation-3: -what statement could be used as evidence to show that two different species of organisms most likely developed from a single, common ancestor? fossil evidence indicated that many species have existed relatively brief periods of time have have become extinct.
Detailed explanation-4: -what are two types of evidence that suggest that evolution has occurred? fossil evidence and molecular evidence. how do fossils provide evidence that evolution has taken place? they show that organisms have changed over time.
