Detailed explanation-1: -A large brain, long legs, the ability to craft tools, and prolonged maturation periods were all thought to have evolved together at the start of the Homo lineage as African grasslands expanded and Earth’s climate became cooler and drier.
Detailed explanation-2: -Allen’s rule is a biological rule that says the limbs of endotherms are shorter in cold climates and longer in hot climates. Limb length affects the body’s surface area, which helps with thermoregulation. Shorter limbs help to conserve heat, while longer limbs help to dissipate heat.
Detailed explanation-3: -During the period of climatic fluctuations in the Holocene era, humans began to domesticate plants and animals and subsequently adopted agriculture. These adjustments later led to sedentary settlements and the expansion of urban-based societies.
