- Describe using specific examples how the theory of evolution is supported by the following areas:
Palaeontology, including fossils
The study of fossils.
Transitional forms: EG. Archaeopteryx which is a flying reptile and has a mixture of reptile and bird characteristics and links birds as descendants of reptiles. Has a mixture of: teeth, finger claws, feathred wings and a body tail.
The study of geographical distribution of organisms.
EG. Ratites (flightless birds) and continental drift.
Today's flightless birds suggest these birds originated from a common ancestor on gondwana
Also different populations evolved on isolated southern continents as they drifted apart
Emu - australia
Ostriches - south africa
Kiwis - new zealand
Rheas - south america
Is the comparision of the developmental stages of different species.
Linking one organism to another. All living organisms share an aquatic ancestor.
The study of similaraties and differences and differences in structure (anatomy) of living organisms that show relatedness of a species.
Similar ancestory - similar bone structures have developed differences due to environmental pressures.
EG. Humans, cats, whales and bats all have (humerous, radius and ulna, carpal, metacarpals and 5 phalanges)
The study of chemicals found in cells, includes the study of molecular biology and genetics.
All living things contain the same macromolecules such as DNA and proteins (enxymes)
