Endosymbiotic Theory Mitochondria Chloroplast
Evidence for Evolution…or COMMON ANCESTRY Homologous Structures Traits that are similar in different species because the species share a common ancestor. Same structure, different function
EVIDENCE OF EVOLUTION… or COMMON ANCESTRY MOLECULAR HOMOLOGIES GENETIC SEQUENCES SHOW SIMILARITIES AMONG ORGANISMS. EXAMPLE: HUMAN GENOMES AND CHIMPANZEE GENOMES ARE 99% IDENTICAL
EVIDENCE OF EVOLUTION… or COMMON ANCESTRY EMBRYOLOGY HOMOLOGIES EMBRYOS
EVIDENCE OF EVOLUTION… or COMMON ANCESTRY FOSSIL RECORDS YOUNGEST OLDEST FOSSIL RECORDS CAN BE USED AS A TIME LINE OF HOW LIFE HAS EVOLVED
