Hominid migration refers to the movement of early human ancestors out of Africa and their subsequent spread across the globe, driven by environmental changes, resource availability, and evolutionary adaptations. This process was crucial in shaping the genetic diversity and cultural development of modern humans, as different populations adapted to varied ecological niches over time.

Environmental changes refer to the alterations in the natural or human-made environment that can affect ecosystems, biodiversity, and human societies. These changes can be driven by natural processes or human activities, leading to impacts such as climate change, habitat loss, and pollution.

Environmental Changes

Resource availability refers to the accessibility and abundance of necessary resources, such as materials, energy, and labor, required for a system or process to function effectively. It plays a critical role in determining the sustainability and efficiency of operations across various sectors, influencing decision-making and strategic planning.

Resource Availability

Evolutionary Adaptations

Genetic diversity refers to the total number of genetic characteristics in the genetic makeup of a species, which is essential for populations to adapt to changing environments and ensures long-term survival. High genetic diversity increases a species' ability to withstand diseases and environmental changes, while low diversity can lead to inbreeding and increased vulnerability to extinction.
