Study Notes
Biological Evolution
- Involves the transformation of modern humans from hominids, emphasizing cognitive development.
Cultural Evolution
- Refers to the progression of cultures from simple to complex forms, reflecting societal advancements.
Socio-Cultural Evolution
- Occurs due to human adaptation to environmental changes, such as climate and population density.
Macroevolution
- Focuses on speciation (formation of new species) and the evolutionary relationships among species groups.
Homeobox Genes
- A specific group of genes that regulate development processes like cell differentiation and morphogenesis in multicellular organisms.
Natural Selection
- A process favoring specific biological traits that enhance survival and reproduction in particular environments.
Overproduction
- Species typically produce more offspring than can survive to maturity, influencing natural selection.
Variation
- Individuals within a population exhibit varying characteristics, essential for natural selection.
Selection
- Certain individuals endure longer lifespans and reproduce more effectively, impacting population genetics.
Adaptation
- Traits of successful individuals become more prevalent in subsequent generations, reflecting survival advantages.
Australopithecus Afarensis
- Exhibited both ape and human traits; characterized by a flat nose, smaller brain (~500 cubic cm), bipedalism, and adaptations for climbing.
Homo Habilis
- Known as "handyman," this species existed from approximately 2.33 to 1.4 million years ago and was the first known toolmaker.
Homo Erectus
- The oldest species with human-like body proportions; evidence from well-preserved skeletons indicates similar walking and running to modern humans.
Homo Neanderthalensis
- Featured a long, low skull shape with a prominent brow ridge and large nose, distinct from modern human anatomy.
Homo Sapiens
- The only extant human species, recognized for large brains, complex language, and abilities for cooperation in hunting and building.
Lower Paleolithic Period
- Marked by the existence of Homo Erectus, characterized by the production of specialized tools like hand axes for specific tasks.
Middle Paleolithic Period
- Associated with Homo Sapiens, this era saw advancements in tool efficiency, facilitating various labor tasks such as lifting and pulling.
Upper Paleolithic Period
- Identified by the presence of Homo Sapiens Sapiens, featuring the development of specialized tools, including long blades, and increased population activities.
Neolithic Period
- Also known as the Agricultural Revolution, representing a significant transitional phase from nomadic hunter-gatherers to settled agricultural societies and early civilizations.
