Evidences of Evolution

• Fossils are preserved remains or traces of organisms from past geological periods, found in rocks.
• Geographical Evidence (Biogeography):

  Geographical distribution of various life forms on Earth.
• Analogous structures are similar structures in organisms without shared ancestry. These structures evolved independently to serve the same purpose.
• HOMOLOGOUS STRUCTURES are common features in the structures of different organisms.
• Fossil Reconstruction

  The bones from fossils are assembled and a detailed drawing or reconstruction is made of the skeleton.
• Fossils:

  FOSSILS are mineralized/ hardened traces of dead organisms most found in layers of sedimentary rocks.
• VESTIGIAL STRUCTURES

  A vestigial structure is an anatomical feature or behavior that no longer seems to have a purpose in the current form of an organism
• Biochemical Evidence :(Molecular) DNA, Amino Acids, Cytochrome C are similar in related organisms
• Embryology: An EMBRYO is an unborn animal in its earliest phases.
• ANATOMICAL STRUCTURES:

  HOMOLOGOUS STRUCTURES are common features in the structures of different organisms.
