It is likely that people lived in the temperate zones of the Earth before that last glacial period began, along with other animals and plants. When the glaciers advanced during the last Ice Age, people had to move to warmer areas of land nearer to the equator.
As the glaciers receded after the maximum glaciation had occured, modern humans were able to migrate from the belt of land around the Earth's equator and settle the new temperate zones.

In what ways does climate affect life?
Climate affects life in various ways, including influencing the type of vegetation that can grow, determining the availability of water sources, impacting animal behavior and migration patterns, and affecting human health and livelihoods. Changes in climate can lead to shifts in ecosystems and habitats, impacting biodiversity and the overall balance of natural systems.
Why is the climate of an area so important to the success of a country?
The climate of an area influences agriculture, natural resources, and human health. A favorable climate can lead to abundant food production, economic growth through agriculture, and overall well-being of the population. Conversely, a harsh climate can limit resources, impact infrastructure, and drive migration.
How does orbital change effect climate?
Changes in Earth's orbital parameters, such as its tilt or its distance from the sun, can affect the distribution of solar radiation received by different parts of the planet. These changes can influence the climate by altering the amount and distribution of sunlight reaching Earth's surface, which in turn can impact temperatures, weather patterns, and ultimately lead to changes in global climate. However, orbital changes occur over long timescales (tens of thousands to hundreds of thousands of years) and are not the primary drivers of the shorter-term climate changes we are currently experiencing.
How changes in the number of sunspots is related to changes in global climate?
Changes in the number of sunspots can affect global climate by influencing solar radiation levels. More sunspots can lead to increased solar activity, resulting in slightly higher temperatures on Earth. Conversely, fewer sunspots can lead to a decrease in solar activity, potentially causing cooler temperatures. This is known as the solar cycle and is just one of many factors influencing global climate.
What are some effects of a dry and cold Arctic climate?
A dry and cold Arctic climate can lead to permafrost formation, which can impact infrastructure stability and plant growth. It can also result in low biodiversity and slow decomposition rates, affecting nutrient cycling in the ecosystem. Additionally, the cold temperatures can impact animal survival and migration patterns.
How did enviormental changes in the great plains lead to changes in migration?
A sever drought forced many to migrate west.
How did environmental changes in the Great Plains lead to changes in migration?
A severe drought forced many to migrate west.
How did environmental changes in the great plains lead to the changes in migration?
A severe drought forced many to migrate west.
What is the impact of migration on language?
Migration can lead to language shifts or changes as people interact with new linguistic communities. Over time, migrants may adopt elements of the local language, leading to language mixing or bilingualism. Additionally, migration can also lead to the preservation of languages through diaspora communities.
How are organisms and populations affected by environmental changes?
Organisms may experience changes in their habitat, food availability, and climate due to environmental changes, which can lead to shifts in behavior, reproduction, and distribution. Populations may decline if they cannot adapt to these changes, leading to reduced genetic diversity and increased vulnerability to diseases and other threats. Adaptation, migration, and extinction are some of the responses organisms and populations may have to environmental changes.

For a given species the three alternatives to selective pressures are adaptation migration and?
The three alternatives to selective pressures are adaptation, migration, and genetic drift. Genetic drift refers to random changes in the gene pool of a population that can lead to changes in allele frequencies over time, independent of natural selection.
What are the three ways that migration affects people and lands?
Economic impact: Migration can lead to changes in labor markets and distribution of resources, affecting both the sending and receiving countries. Social impact: Migration can influence cultural exchanges, social dynamics, and community cohesion in both the origin and destination areas. Environmental impact: Migration may contribute to increased pressure on natural resources, land use changes, and environmental degradation in areas experiencing high levels of migration.
What is thermal migration?
Thermal migration refers to the movement of atoms or molecules within a material in response to temperature changes. This can lead to the redistribution of constituents within the material, affecting its properties such as mechanical strength or conductivity. Thermal migration is commonly observed in materials undergoing thermal processing or experiencing temperature gradients.
