Breast-Feeding from an Evolutionary Perspective.

Area of Science:

• Evolutionary Biology
• Human Physiology
• Anthropology

Background:

• Lactation is a critical mammalian feeding period, with human infant feeding evolving from natural breastfeeding to artificial formulas.
• Debates persist regarding the advantages and disadvantages of natural versus artificial lactation from biological, psychological, and cultural viewpoints.
• Abundant information on breastfeeding often complicates objective knowledge acquisition and decision-making for mothers and health professionals.

Purpose of the Study:

• To analyze infant feeding from a biological evolution perspective, focusing on the mother-child dyad.
• To examine mother-infant conflicts, including weaning, lactase deficiency, and the prevention of adult diseases.
• To provide a perspective on the biological and cultural aspects of infant feeding.

Main Methods:

• Review of biological evolution principles related to lactation.
• Analysis of mother-infant dyad dynamics and conflicts.
• Examination of lactase deficiency and long-term health implications.

Main Results:

• Lactation is fundamental to mammalian species survival, including humans.
• Mother-infant interactions and conflicts, such as weaning, are significant evolutionary considerations.
• Understanding infant feeding impacts long-term health and disease prevention.

Conclusions:

• Breastfeeding is a cornerstone of human evolution and species survival.
• Biological and cultural factors significantly influence infant feeding practices and outcomes.
• Further understanding of lactation's evolutionary role can inform infant feeding decisions and health strategies.
