Why did wholly mammoths have a trunk?

Woolly mammoths had trunks primarily for feeding, as they used them to grasp and manipulate vegetation, including grasses, leaves, and shrubs in their cold, tundra habitats. The trunk also served other functions, such as drinking water, social interactions, and regulating body temperature. This versatile organ was essential for their survival in harsh environments, allowing them to efficiently gather food and navigate their surroundings.
