Cultural evolution refers to the way cultures change and develop over time. This process can occur through various means, such as innovation, social learning, and the exchange of ideas between different groups. As societies adapt to new environments or challenges, their customs, beliefs, and technologies may evolve, leading to new cultural practices. Factors like migration, trade, and communication play significant roles in cultural evolution. When people from different backgrounds interact, they share their traditions and knowledge, which can lead to the blending of cultures. This ongoing process helps shape the identities of communities and influences how they respond to the world around them.
