Detailed explanation-1: -Behaviors that are passed from parent to offspring are called instincts. Many animals are born with instincts that help them survive.
Detailed explanation-2: -Babies are born with specific reflexes to help them survive • Instincts are behaviors that are inherited.
Detailed explanation-3: -Among the traits found most strongly determined by heredity were ambition, vulnerability to stress (neuroticism), leadership, risk-seeking, a sense of well-being and, surprisingly, respect for authority. The genetic factor for these traits was found to run somewhere in the region of 50 to 60 percent.
Detailed explanation-4: -Heredity: the passing of traits from parents to offspring before birth.
Detailed explanation-5: -He says the key mechanism for developing instincts that get passed down could be epigenetics, which he says, “is a change in the function or activity of aspects in the genome without a change in the DNA.” Research paper in Science: Epigenetics and the evolution of instincts.
