In this lecture, we continue exploring the important and advanced branches of Ethology that explain behaviour from evolutionary, developmental, social, and molecular perspectives.

6️⃣ Phylogeny of Behaviour

• Studies the evolutionary origin and development of behavioural traits.
• Traces behaviour through evolutionary history.
• Explains how behaviours evolved and diversified among species.

7️⃣ Ontogeny of Behaviour

• Studies the development of behaviour within an individual organism.

Sub-branch: Behavioural Embryology
• Examines prenatal development of behavioural patterns.

8️⃣ Human Ethology

• Applies ethological methods to study human behaviour.
• Focuses on genetically determined and evolutionarily transmitted behaviours in humans.

9️⃣ Sociobiology

• Developed during the 1960s–1970s.
• Studies biological and evolutionary basis of social behaviour.
• Examines adaptive significance of social systems.
• Explains altruism and social organization.
• Lies between ethology and population biology.
• Interdisciplinary field combining behavioural science, ecology, and evolutionary theory.

Influenced by:
• Charles Darwin
• David Lack
• E. O. Wilson – Author of Sociobiology: The New Synthesis

🔟 Sociogenomics

• Newly emerged branch.
• Studies social behaviour at molecular and genomic levels.
• Explains evolution of complex social behaviours from simpler ancestral forms.

1️⃣1️⃣ Bioacoustics

• Studies sound production and perception in animals.
• Uses recording equipment and sound spectrograms.
• Investigates vocal cords, stridulating organs, wings, feathers, etc.
• Examines mechanical and physiological processes of sound production.
• Studies relationship between vocalization and habitat.
• Important for understanding behavioural development (ontogeny).

1️⃣2️⃣ Biological Rhythms (Biorhythms)

• Studies rhythmic and recurring behavioural patterns.
• Includes circadian and seasonal rhythms.
• Important component of behavioural science.

This lecture is especially useful for BSc, MSc Zoology students, Life Science learners, and competitive exam preparation.
