Study Notes
Primate Evolution
- Primates evolved approximately 70 million years ago in Africa.
- Out of roughly 5,000 mammal species, about 360 are classified as primates.
- Humans are categorized within the family Hominidae.
- Key adaptations of primates include:
- Development of social structures and caregiving for offspring.
- Evolution of opposing thumbs for enhanced grip.
- The East African Rift Valley caused geographic isolation, separating populations into rainforests and savannahs.
Human Evolution
- The human lineage diverged approximately 7 million years ago.
- Essential adaptations in early humans included:
- Bipedalism (walking on two legs) leading to an upright posture.
- Development of tool usage for various tasks.
- First recognizable humans appeared around 2.8 million years ago.
- Significant traits included:
- Larger brain capacity compared to earlier ancestors.
- Mastery of fire usage for cooking and protection.
- Emergence of speech for communication.
- Significant traits included:
- Homo sapiens emerged around 200,000 years ago.
- A bottleneck event drastically reduced the population to as few as 10,000 individuals.
Cultural Evolution
- Cultural evolution involves the transmission of knowledge across generations, enhancing communal awareness.
- Humans have become less reliant on natural resources, demonstrating the ability to manipulate environments for benefit.
- This shift has contributed to biodiversity loss and climate change, impacting both nature and other species.
