How did Homo erectus navigate and survive harsh weather conditions during its migrations?
user
One theory is that Homo erectus might have used primitive maps, such as landmarks or natural features, such as mountain ranges or coastlines, to navigate during their migrations. These maps would have helped them to find their way back to their original habitats, even if they got lost or separated during their travels.

Additionally, Homo erectus may have adapted to different weather conditions they encountered during their migrations, such as by developing shelter that could withstand harsh winds, rain, and snow. They might have also developed warm clothing or fire to keep them warm during colder weather.

Overall, Homo erectus' ability to navigate and survive in different environmental conditions during their migrations was likely due to a combination of their physical abilities, social organization, and technological advancements.

How did Homo erectus navigate and survive harsh weather conditions during its migrations?
user
Homo erectus likely used a combination of physical adaptations and behavior to navigate and survive harsh weather conditions during its migrations. 

Physically, Homo erectus had a larger brain and body size compared to earlier hominins, which allowed them to better regulate body temperature and maintain energy reserves during periods of low food availability. Additionally, they likely had thicker skin and hair to protect themselves from cold conditions.

Behaviorally, Homo erectus may have used fire to keep warm and cook food during cold weather. They may have also migrated to areas with more temperate climates during harsher seasons. 

It's also important to note that Homo erectus existed over a long period of time and in many different regions, so their specific adaptations and survival strategies likely varied depending on their location and environment.
