The Role of Genetic Memory in Human and Animal Behavior

The Evolutionary Basis for Humans' Longer Period of Dependence on Parents

Humans have a longer period of dependence on their parents compared to other animals, and this can be attributed to the prioritization of brain development in our species' evolution. If humans were to stay in the womb until they reached the same developmental level as newborn horses or cows, it would be physically impossible for mothers to carry them, as our spines and pelvises have evolved differently.

Genetic Memory: Instincts and Behaviors Passed Down Through Generations

Animals' ability to instinctively know how to perform certain behaviors is not just instinct but also genetic memory. Newborn creatures are born with a set of behaviors passed down through genetics. For example, birds know how to build nests specific to their species using appropriate materials and in the correct location and environment, even if they have never seen one before.

Genetic Memory in Humans: Instincts and Recognition

Humans have also retained some level of genetic memory. Infants instinctively know how to suckle and turn towards warmth, and they cry for attention. Research experiments have shown that humans have a strong ability to recognize and remember dangerous creatures like snakes, spiders, and sharks, suggesting that this recognition is burned into our genetic memory. Humans can also feel the terror of being stalked by a predator, triggering the fight or flight response.

Learning and Genetic Memory in Animals

Some animals, like birds, learn how to perform certain behaviors from their parents, while others are born with genetic memory. During the period when birds are learning to fly, they can be seen hopping around on the ground with their parent birds trying to teach them how to fly. This learning period is crucial for their survival and independence.

Imprinting and Genetic Memory in Humans

Humans also have a level of imprinting on their mothers that happens right after birth, which can be considered a form of genetic memory. This imprinting helps establish a bond and attachment between the infant and the mother. Additionally, humans have instinctive fears, such as spiders, snakes, and wolves, which can also be attributed to genetic memory.

Evolutionary Factors in Human Development

Animals that are born "fully cooked" have a higher level of independence and are able to perform necessary behaviors immediately after birth. However, due to humans' longer period of brain development outside the womb, we require a longer period of dependence on parents. The development of humans' up***ht walking has led to changes in our spines and pelvises, making it impossible to carry a baby inside the body beyond a certain point.

Genetic memory plays a significant role in both human and animal behavior. While some animals learn behaviors from their parents, others are born with the ability to perform them instinctively. Humans, with their longer period of dependence on parents, have retained genetic memory in the form of instincts and recognition. This genetic memory helps shape our behavior and aids in our survival.
