Introduction to Zoology

• Zoology is the scientific study of animals.
• It covers a broad range of subjects, including animal behaviour, physiology, evolution, and ecology.
• The introductory semester focuses on fundamental concepts and basic knowledge.

Animal Diversity

• Animal classification and taxonomy: Organising animal life into groups (kingdom, phylum, class, order, family, genus, species) based on shared characteristics.
• Diverse animal phyla: Examples include Porifera (sponges), Cnidaria (jellyfish, corals), Platyhelminthes (flatworms), Annelida (segmented worms), Mollusca (snails, clams, octopus), Arthropoda (insects, crustaceans, spiders), Echinodermata (starfish, sea urchins), and Chordata (vertebrates).
• Unique characteristics and adaptations of each phylum: For instance, Annelida's segmented bodies, or Arthropoda's exoskeletons.

Animal Cell Biology

• Cell structure and function: Animal cells have fundamental components like plasma membranes, cytoplasm, nucleus, and organelles (mitochondria, ribosomes, endoplasmic reticulum).
• Cellular processes: Essential topics include metabolism, cell division (mitosis and meiosis), protein synthesis, and respiration.
• Animal tissues: Different tissue types (epithelial, connective, muscle, nervous) perform specific functions within organisms.

Animal Physiology

• Homeostasis: Maintaining a stable internal environment is crucial for survival, including temperature regulation, blood sugar control, and water balance.
• Organ systems: Animals have specialized organ systems (digestive, respiratory, circulatory, nervous, excretory) that contribute to homeostasis.
• Specific mechanisms within each system: Exploring the details like digestive enzyme functions or hemoglobin's role in oxygen transport.

Animal Genetics and Evolution

• Mendelian genetics: Understanding the patterns of inheritance.
• Basic genetics: The study encompasses DNA structure, gene expression, mutation, and genetic variation.
• Evolution: Explaining animal change over time via adaptations, natural selection, and common ancestry. Speciation and diversification are also discussed.

Ecology

• Basic ecological principles: Understanding populations, communities, ecosystems, and interactions between them.
• Biodiversity: The importance of life diversity and factors impacting its loss.
• Ecosystem interactions: Interactions like predator-prey relationships, competition, symbiosis, and nutrient cycling.
• Biomes: The classification of terrestrial and aquatic environments.

Animal Behavior

• Behavioral ecology: Studying animal behaviour in relation to their environment.
• Innate behaviors: Fixed, inherited behaviours (reflexes, instincts).
• Learned behaviors: Behaviors acquired through experience (imprinting, classical conditioning).
• Communication and social behaviour in animals.

Practical Work/Laboratory sessions

• Practical exercises: Dissections, observations, and analysis of animal specimens.
• Classification practice: Classifying animals based on key features.
• Data collection and analysis: Applying scientific methods through experiments and observations.

Additional Potential Topics

• Developmental biology: Animal development from zygote to adult stage.
• Animal diseases and parasites: Potential study areas.
• Ecology and conservation: Potential topics depending on the curriculum.
