A Strong Sex or Both Sexes Strong?

The Dilemma of Man vs. Woman Hunter-Gatherers

When comparing the human life cycle and ages of life with those of our closest living relatives, there are significant differences. Female chimpanzees are virtually fertile until the day they die.

Scientists think that menopause occurred so mothers could help their daughters raise their grandchildren; this is called the “Grandmother Hypothesis.” On the other hand, the Grandmother Hypothesis

EU Policies: Agriculture, Industry, Services & Spain

Natural and Human Factors: An In-Depth Analysis

Natural Factors

Natural factors include a number of components, such as: location, size, topography, soil, coasts, climate, hydrography, flora, and fauna. This enumeration, adopting a principle of order, is not arbitrary. The approach is based on the degree of difficulty for modifying the natural elements. The surface area and geographical location are unchanged, but there are possibilities of transformation. Thus, we cannot move mountains, but it is technically possible to trace tunnels through
