EVIDENCES OF EVOLUTION

EVOLUTION

THE CHANGE IN INHERITED TRAITS OVER SUCCESSIVE GENERATIONS IN POPULATION OF ORGANISM, THIS ALLOWS ORGANISM TO ADAPT AND SURVIVE IN THEIR ENVIRONMENT

FOSSIL RECORD

REMAINS OR TRACES OF AN ORGANISM THAT NLIVED LONG AGO

TRACES

SHALLOW EXTERNAL MOLDS LEFT BY ANIMALS OR PLANT TISSUES WITH LITTLE OR NO ORGANIC MATERIAL PRESENT

REMAINS

ANIMALS OR PLANTS TISSUES PRESERVED IN SEDIMENTARY ROCKS AND IS FROMED WITH MORE ORGANIC MATERIAL

COMPARATIVE ANATOMY

STUDY OF SIMILARITIES ANDDIFFERENCES IN THE STRUCTURES OF DIFFERENT SPECIES (HOMOLOGOUS, ANALOGOUS, VESTIGIAL)

HOMOLOGOUS STRUCTURES

BODY PARTS OF ORGANISM THAT MAY PERFORM DIFFERENT FUNCTIONS BUT ARE OF THE SAME ORIGIN

ANALOGOUS STRUCTURES

BODY PARTS OF ORGANISMS THAT MAY PERFORM THE SAME FUNCTIONS BUT ARE OF THE DIFFERENT ORIGINS

VESTIGIAL STRUCTURES

BODY PARTS THAT ARE USELESS OR LEFT OVER FROM A PREVIOUS ANCESTOR IN WHICH THEY WERE USEFUL

COMPARATIVE EMBRYOLOGY

TGHE PORTION OF LIFE CYCLE THAT BEGINS JUST AFTER FERTILIZATION, MAY ORGANISM HAVE SIMILAR EMBRYOS SUPPORTING THE IDEA OF COMMON ANCESTRS

MOLECULAR BIOLOGY( GENETIC INFO)

SMALL MUTATIONS OR CHANGES IN THE DNA EVENTUALLY LEAD TO THE EVOLUTION OF NEW SPECIES, MORE THAN 98% OF DNA SEQUENCES ARE IDENTICAL IN HUMAN AND CHIMPANZEES

BIOGEOGRAPHY

THE USE OF GEOGRAPHY TO DESCRIBE THE DISTRIBUTION OF SPECIES

DIVERGENT EVOLUTION

AFTER HE SUPERCONTINENTAL PANGAEA SEPARATED, SIMILAR SPECIES DIVERGED DUE TO DIFFERENT ENVIRONMENTS

CONVERGENT EVOLUTION

PROCESS WHERE UNRELATED SPECIES FROMDIFFERENT REGIONS AROUND THE WORLD CONVERGE OR BEGIN TO LOOK ALIKE WHNE FOUND IN SIMILAR ENVIRONMENT
