La evolución del esqueleto humano: caminar en dos piernas

The video explores the evolution of the human skeleton from ape-like ancestors to modern humans. It highlights anatomical changes such as longer legs and altered arm sizes that facilitated bipedalism. Walking on two legs, known as bipedalism, is energy-efficient and allows humans to use their hands for tasks like hunting and tool-making.

What is the primary focus of the first section of the video?

• The migration patterns of early humans

• The evolution of the human skeleton over millions of years

• The invention of tools

• The development of human language

Which part of the human skeleton lengthened over time to aid in bipedalism?

• Legs

• Ribs

• Skull

• Arms

What significant change in the human skeleton allowed for walking on two legs?

• Growth of a tail

• Increase in body hair

• Changes in arm size and skull shape

• Development of wings

What is one benefit of walking on two legs mentioned in the video?

• It enhances swimming ability

• It improves balance on uneven surfaces

• It uses less energy

• It allows for faster running speeds

How did walking on two legs impact early human activities?

• It made them more vulnerable to predators

• It limited their ability to climb trees

• It reduced their need for social interaction

• It freed up their hands for tasks like hunting and tool-making
