WebHomeotic mutations in fruit flies. Homeotic genes are responsible for determining the identity of particular segments or structures of the body. So, when homeotic genes are inactivated or expressed in unusual locations due to mutations, they may cause body segments to take on new—and sometimes startling!—identities. WebEvidence for large-scale evolution ( macroevolution) comes from anatomy and embryology, molecular biology, biogeography, and fossils. Similar anatomy found in different species may be homologous (shared due to ancestry) or analogous (shared due to similar selective pressures). Molecular similarities provide evidence for the shared ancestry of life.
WebI prefer here a definition combining that of Osche (1973, 1982: 21): “Homologies are non-random similarities of complex structures which are based on common genetic … WebThus, symple-siomorphic homology will not confound DNA hybridization phylogenies. However, nonhomologous identities that act like apomorphic homologies can lead to inaccurate reconstructions. The main difference between methods of phylogenetic analysis of DNA sequences is that parsimony methods permit hypotheses of nonhomology, …
