Evidences from Embryology
Evidences of Evolution of Class 12
Stages of embryogenesis in all animals are same e.g. fertilization 
zygote blastulation gastrulation organogenesis
Human embryo pass through all the stages of forms like fishes salamander reptiles birds other mammals man.
Haeckle’s (1866) Biogenetic law (or Recapitulation theory or theory of Paleogenesis) states “Ontogeny repeats phylogeny”
