Lesson 643 of 1524
The Genus Homo and the Emergence of Us
Genetic information provided by mtDNA indicates that all humans shared common ancestors who lived in Africa 200,000 years ago.
Practice this chapterGenetic information provided by mtDNA indicates that all humans shared common ancestors who lived in Africa 200,000 years ago. Studies of genetics shows examples of coevolution and how even small organisms such as lice can shed light on the human story.
The rise of agriculture created new challenges for humanity, with evolutionary mismatch still impacting people today. In this chapter we have explored our human journey as a member of the genus Homo , following a trail of adaptations and change that ultimately led to us .
coevolution — an interaction between different species that influences each species’ evolution; the simplest case of this is predator-prey relationships. evolutionary mismatch — a hypothesis that disease and nutritional deficiencies result when people’s bodies are unable to adapt to an environment that they have not spent most of their evolutionary…. mtDNA — the DNA located in the mitochondria that can be passed down unchanged from female genetic contributor to child. Oldowan tool Industry — the oldest and most primitive tool industry; production and use are largely in association with H. habilis.
Worked example
What does “coevolution” mean in The Genus Homo and the Emergence of Us?
- 1Use the wording this chapter gives for coevolution.
- 2The book says: an interaction between different species that influences each species’ evolution; the simplest case of this is predator-prey relationships.
- 3Do not use the meaning of evolutionary mismatch. That term means a hypothesis that disease and nutritional deficiencies result when people’s bodies are unable to adapt to an environment that they have not spent most of their evolutionary….
Result: an interaction between different species that influences each species’ evolution; the simplest case of this is predator-prey relationships
Why. That is the meaning this chapter gives for coevolution.
Do not swap coevolution and evolutionary mismatch. coevolution means an interaction between different species that influences each species’ evolution; the simplest case of this is predator-prey relationships. evolutionary mismatch means a hypothesis that disease and nutritional deficiencies result when people’s bodies are unable to adapt to an environment that they have not spent most of their evolutionary….
