Hominins adapted arms and hands for weight-bearing.

Answer #1

Answer: False.

Hominins were bipedal just like us. They developed with carved fingers and diminutive thumb. It is suggested that they freed their other two limbs to get an evolutionary advantage for using tools. Tools that can be held in hand and swung in case of any danger or dispute like stones etc. With this advantage, it can easily increase reproductive success. The individual with better throwing can have an advantage in the community and can show their dominance. In the case of females with evolving hands can give them the benefit of protecting themselves and offsprings better than before.

The outstretched hands and arms of a figure skater preparing for a spin can be considered a slender rod pivoting about an axis through its center (Figure 1). When his hands and arms are brought in and wrapped around his body to execute the spin, the hands and arms can be considered a thin-walled hollow cylinder. His hands and arms have a combined mass 9.0 kg . When outstretched, they span 1.6 m ; when wrapped, they form a cylinder...

The outstretched hands and arms of a figure skater preparing for a spin can be considered a slender rod pivoting about an axis through its center. (See the figure below (Figure 1).) When the skater's hands and arms are brought in and wrapped around his body to execute the spin, the hands and arms can be considered a thin-walled hollow cylinder. His hands and arms have a combined mass of 7.5 kgkg . When outstretched, they span 1.8 mm ;...

On average, both arms and hands together account for 13% of a person's mass, while the head is 7.0% and the trunk and legs account for 80%. We can model a spinning skater with her arms outstretched as a vertical cylinder (head, trunk, and legs) with two solid uniform rods (arms and hands) extended horizontally. Suppose a 60.0 kg skater is 1.60 m tall, has arms that are each 74.0 cm long (including the hands), and a trunk that can...
