Homo Sapiens

Homo sapiens is the scientific name for modern humans. They are known for their advanced cognitive abilities and their development of complex societies and cultures. The species Homo sapiens first appeared in Africa about 300,000 years ago and later migrated to other parts of the world.

Physical Characteristics

Homo sapiens are characterized by their upright posture, large brain size, and relatively hairless skin. They have a diverse range of physical appearances, which can be attributed to genetic variations and adaptations to different environments.

Cultural and Behavioral Characteristics

One of the defining characteristics of Homo sapiens is their ability to create and utilize complex tools, develop language, and engage in symbolic behavior such as art and rituals. These cultural and behavioral traits have enabled Homo sapiens to adapt to a wide range of environments and thrive as a species.

LIFE SCIENCE

Ecosystems: Interactions, Energy, and Dynamics

Examine the cycling of matter between abiotic and biotic parts of ecosystems to explain the flow of energy and the conservation of matter.

Analyze and interpret data to provide evidence regarding how resource availability impacts individual organisms as well as populations of organisms within an ecosystem.

Construct an explanation to predict patterns of interactions in different ecosystems in terms of the relationships between and among organisms (e.g., competition, predation, mutualism, commensalism, parasitism).

Engage in argument to defend the effectiveness of a design solution that maintains biodiversity and ecosystem services (e.g., using scientific, economic, and social considerations regarding purifying water, recycling nutrients, preventing soil erosion).
