On the other hand, many evolutionary biologists, in contrast to animal behaviorists, acknowledge some emotions primarily for their survival function. For both animals and humans, fear motivates the avoidance of danger, love is necessary to care for young, and anger prepares one to hold ground. But the fact that a behavior functions to serve survival need not mean that that is why it is done. Other scientists have attributed the same behavior to conditioning, to learned responses. Certainly reflexes and fixed action patterns can occur without feeling or conscious thought. A gull chick pecks at a red spot above it. The parent has a red spot on its bill; the chick pecks the parent’s bill. The gull parent feeds its chick when pecked on the bill. The baby gets fed. The interaction ne
