Final answer:
The three main similarities in learning phases of birds and babies are imitation, exploration, and play, which contribute to their development and survival.
Step-by-step explanation:
The three main similarities in learning phases of birds and babies are c) Imitation, Exploration, Play. These phases are fundamental in the cognitive development and behavioral adaptations necessary for survival.
Vocalization in birds and babies is part of the imitation phase, where younglings learn to communicate. During exploration, both bird chicks and human infants learn to navigate and interact with their surroundings. Play is essential for the development of social skills and physical coordination in both humans and birds.
It is important to note that these learning phases have distinct differences according to the species-specific behaviors, yet the underlying processes like learning to communicate, interact with their environment, and social interaction are remarkably similar.
