Concept:Evidence for evolution comes from structures that indicate common ancestry, such as homologous organs, fossils, and embryonic similarities. Analogous structures from convergent evolution do not prove common descent.
Explanation:Divergent evolution leads to homologous structures (e.g., forelimbs of mammals). These share a common origin and are strong evidence for evolution.
Fossils in sedimentary layers provide direct paleontological evidence of past life forms and their gradual change over time.
Embryological support (e.g., similarities in early vertebrate embryos) was proposed by Heckel; though his recapitulation theory was later disproved, the observed homologies still indicate common ancestry.
Convergent evolution produces analogous structures (e.g., wings of birds and insects). These arise from different ancestors under similar selective pressures and do not show common descent, so they are not considered evidence for evolution.
Answer:B. Convergent evolution of traits like wings of birds and butterflies
