Zoology is the branch of biology concerned with the study animals and animal kingdom. It is also known as animal biology. The study of zoology includes the interaction of animal kingdom in their ecosystems such as classification, habits, structure, embryology, distribution, evolution, and extinct species.

Zoology is the division of biology that deals with the animal kingdom. It is the scientific study related to the entire species of the animal kingdom.

An ancient Greek philosopher, Aristotle, was a first-person to broadly classify the living things in the 4th century BC. Firstly he divided living things into animals and plants and then continued with his further classifications. Later the words like biology, botany, and zoology came into existence.

The study of zoology includes animals physiology, their behaviour, and their interaction with other species in their environment. It is a huge course that includes the distribution of every animal species on earth including extinct animals. Apart from the animal kingdom and ecosystem, zoology also explores the new areas of research.

Later, Aristotle divided animals into two classes: one with red-blood and another without such as insects and crustaceans. Then, he further classified creatures into those who were able to walk, flow and swim.

The classification by Aristotle was followed until the 16th century, during the Age of enlightenment, scientists finally began to research closely. Now, zoology has become much more complex, where the living things are divided into five kingdoms, in which animal kingdom themselves divided into several smaller categories of Phylum, Class, Order, Family, Genus and, finally, Species.

Characteristics of Life

An organism is an individual form of life, such as a plant, animal, bacterium, protist, or fungus that is made up of organs, organelles, or other parts that work together to carry on the various processes of life.

To be considered living an organisms must exhibit the following characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing.

The Nature of Science

The nature of science is the basic concept that governs the way scientists explain the natural world based on empirical evidence from observations and experimentations.

The basic understandings about the nature of science are:

▪ Scientific Investigations Use a Variety of Methods

▪ Scientific Knowledge is Based on Empirical Evidence

▪ Scientific Knowledge is Open to Peer Revision in Light of New Evidence

▪ Scientific Models, Laws, Mechanisms, and Theories Explain Natural Phenomena

Questions for Today 1.What is the Nature of Science? 2.What are the differences between a theory and a law? 3.What are the differences between inductive. - ppt download
