Zoology attracts students from diverse backgrounds with a range of interests such as animal care and welfare through to concerns about sustainability. If you have an interest in the natural world then this Level 3 Diploma in Zoology qualification could be just for you. The study of zoology combines elements of biology, psychology and environmental sciences and teaches us how to care for, conserve and respect all animal life.

This Level 3 Diploma in Zoology qualification explores the origin of life and how it has been able to diversify in so many ways. Over the course of 7 units, learners will study how life has changed from single-celled organisms into the many different types of animal life we see around us today. This comprehensive qualification looks at how mammals evolved and how they became the dominant vertebrates. Learners will examine the important roles of food, reproduction and habitat and the related species adaptations. The qualification concludes with a look at biodiversity and the importance of conservation.

This Level 3 Diploma in Zoology is relevant to those working or wanting to work in the many careers related to zoology, as well as those wanting to improve their knowledge in the field. A sound knowledge of zoology will support a number of careers in the wildlife and conservation sectors. Learning is flexible and study is conducted online with the support of a dedicated tutor.

Unit 1

Origin of Life and Evolutionary Theory

This unit explores how and when life began on earth and what life was like in the beginning. Learners will study the key figures in evolutionary theory and gain an understanding of natural selection and how traits are inherited.

Unit 2

Animal Diversity

An introduction to the huge array of animal life will be covered. The unit examines all the major phyla of animal life from the “simple” protozoan and radiate animals through to the invertebrates and vertebrates. Learners will study how the classes evolved and how different animals are related to one another.

Unit 3


This unit looks at how mammals evolved. Learners will be able to identify the three sub-classes of mammals and the features that make them distinct. Learners will consider why these features have made mammals the dominant vertebrates of modern times.

Unit 4

Animal Form and Function

The vast array of animal body plans and how they differ from each other are discussed in this unit. Learners will understand the basic requirements that a multicellular animal must have to function and explore homeostasis.

Unit 5

Finding Food

Food is essential to all life and so this unit explores the feeding strategies of omnivores, herbivores, detritivores and carnivores. Case studies highlight how different animals have evolved the ability to locate, store, consume and digest food. The unit also looks at the various ways that prey have evolved to avoid predation.

Unit 6


This unit examines the meaning of asexual and sexual reproduction, taking into account the different types of mating systems and how animals choose their mates. Learners will be able to identify how animals ensure fertilization and how intersexual conflict can occur.

Unit 7

Animals and their Environments

This unit focuses on the different environments animals live in and the geographical distribution of animals across the globe. Learners will explore the importance the environment plays in species adaptation and the impact urbanisation has on habitats and how animals have adapted to urban areas.

ZSL Fellowship

When you study a wildlife, zoology or conservation course with Animal Courses Direct, you will be eligible to apply for ZSL Fellowship. Fellows get unlimited access for them and a family guest to ZSL London and Whipsnade Zoos plus borrowing rights in the extensive ZSL library of rare zoological texts. Enrol on your course and apply directly to ZSL for Fellowship.

*You will have access to the course for 12 months only, after which, you can purchase extensions.


A zoologist’s job is to understand these animals on a species level; how they came to be, live, feed, and breed. It is also to grasp how these individual species interact and affect each other as well as their environments.
