Is a science concerned with the study of man
Main focus: the feature that is unique to humans – the cultural behavior.

Paleontological Evidence of Evolution: The Fossil Record
Paleontology – the study of extinct animals.
- the study of remains of ancient organisms that are occasionally preserved in earth layers of different age.
Fossils – remains of the past organisms
![Page 5: Lec 3 socio](https://reader036.fdocuments.in/reader036/viewer/2022062319/55861e25d8b42abe278b5137/html5/thumbnails/5.jpg)
Fossils: SkeletonImprints of body structuresFrozen animals Preserved animals found in
logs

Fossil recordAdds time depth to the
biological pictureYields actual ancestral types
from which relatively similar living forms of organisms could have been derived
Provides diachronic proof of common ancestry

Dating Pre-Historic RemainsMethods:
Relative Dating Method Is used if the concern
evolutionary sequences makes important to know which forms of life came after which.
Object/specimen can be arranged in chronological order but the exact age may not be known.
Ex: flourine, uranium, & nitrogen tests
![Page 8: Lec 3 socio](https://reader036.fdocuments.in/reader036/viewer/2022062319/55861e25d8b42abe278b5137/html5/thumbnails/8.jpg)
Absolute MethodCan determine the exact or approximately
exact ages.Determines the evolutionary sequences of
two crucial fossils or cultural depositsEx: (a) Physico chemical dating (uses
uranium & thorium); (b) Potassium argon dating (used to determine the age of rocks in deposits, not the fossil)
Dating Pre-Historic Remains
![Page 9: Lec 3 socio](https://reader036.fdocuments.in/reader036/viewer/2022062319/55861e25d8b42abe278b5137/html5/thumbnails/9.jpg)
Carbon 14 (C14) dating◦ Used with organic materials like wood,
bone seeds, & other organic materials. Biological Analysis
(a) Pollen Analysis or Polynology – analyzes the relative frequencies of different kinds of pollen in reconstructing local climatic conditions in recent deposits.(b) Dendrochronology (tree-ring dating) – it uses the fact that tree grows faster in wet years than in dry years, shown on the annual growth rings.

Mechanisms of Human Evolution (The Origin of Man)
How do species originate?
Has it undergone the gradual process of evolution over a number of generations?
![Page 11: Lec 3 socio](https://reader036.fdocuments.in/reader036/viewer/2022062319/55861e25d8b42abe278b5137/html5/thumbnails/11.jpg)
Natural Selection (Charles Darwin, 1882 & Alfred Wallace)They demonstrated that inheritable
variations are differentially affected by the environment.
They asserted that those who possess adaptively valuable qualities in their environment will be at an advantage in comparison with those who do not possess such qualities

Genetics (Gregor Mendel)Genes – carry hereditary traits
- subject to occasional unpredictable alterations (mutations)

Origin of Man
The Bible says that God created man
Evolutionary theories say that man evolved from apes

Human EvolutionProconsul
Discovered by Leakey in Rusinga Island
3 species:Proconsul Africanus (gibbon-sized type)
Proconsul Nyanzae (chimpanzee-sized type)
Proconsul Major (gorilla-sized type)
![Page 16: Lec 3 socio](https://reader036.fdocuments.in/reader036/viewer/2022062319/55861e25d8b42abe278b5137/html5/thumbnails/16.jpg)
Ramapithecus brevirostis Emerged from dyopithecinesDiscovered where lateral incisors,
premolars and the first 2 molars showed that the upper jaw was more manlike.
Its dental structures points squarely in the direction of man.

AustralopithecinesExtinct ape men of early
Pleistocene AfricaFeet and legs were
thoroughly man-likeSkulls were more ape-likeTeeth, bones of lower
extremities and the hips are more human-like

Human Evolution Pithecanthropus

indistinguishable from those of modern humans.
Teeth are essentially modern
