Which mutation provided an advantage for food collecting but was detrimental when it came to food eating?

The mutation that provided an advantage for food collecting but was detrimental for food eating is often associated with the development of larger body sizes in some species. While larger bodies can help individuals access a wider range of food sources, they may also result in higher energy requirements and difficulties in processing certain types of food efficiently. This trade-off illustrates the balance between foraging advantages and the metabolic costs of consuming food.
