Learners will develop a detailed understanding of the formation of the Earth within the context of the solar system and the specific conditions that made it suitable for supporting life. They will explore the origins of life, examining how simple life forms first appeared and the major events that contributed to the development and evolution of increasingly complex organisms over time.The unit will also introduce learners to key figures in evolutionary theory, such as Charles Darwin, Alfred Russel Wallace, and Jean-Baptiste Lamarck. Learners will examine the significance of their contributions, including how their ideas shaped our modern understanding of biology and influenced scientific thought.

A focus will be on natural selection, how it drives evolutionary change, and the mechanisms through which traits are inherited from one generation to the next. Learners will study examples of adaptation in the natural world and explore how environmental pressures can lead to changes in species over time.

By the end of the unit, learners will have a well rounded foundation in evolutionary biology, enabling them to understand how life on Earth has changed, adapted, and diversified over billions of years.

Learners will develop a comprehensive understanding of animal diversity by exploring how and why animals are classified into different phyla based on shared physical and biological characteristics. This unit will introduce the principles of biological classification and taxonomy, helping learners grasp the importance of organising the animal kingdom in a logical, evolutionary framework.

A focus will be on the main invertebrate phyla, such as Arthropoda, Mollusca, Annelida, Cnidaria, and Echinodermata. Learners will examine the defining features of each group, their body structures, methods of reproduction, locomotion, and ecological roles. Through comparing these groups, learners will begin to understand the immense variety of form and function within the invertebrate world.

The unit will also explore the phylum Chordata, with particular attention to the evolutionary development of the vertebrate classes including fish, amphibians, reptiles, birds, and mammals. Learners will study the distinguishing characteristics of each class and how these adaptations reflect their environments and lifestyles. The evolutionary relationships between vertebrates will be analysed to highlight key transitions, such as the move from water to land or the development of flight and endothermy.

By the end of the unit, learners will have a solid foundation in animal classification and evolutionary biology, enabling them to appreciate the complexity and diversity of life forms and their evolutionary connections.

Learners will develop a detailed understanding of mammalian evolution, tracing the origins of mammals from their reptilian ancestors through to the wide diversity of modern species seen today. They will explore the major evolutionary milestones, such as the development of endothermy, live birth, and complex brains, which enabled mammals to adapt to a broad range of environments and ecological niches.

The unit will also focus on the three main sub-classes of mammals,Monotremes, Marsupials, and Placentals, examining the key characteristics that distinguish each group. Learners will study the unique reproductive methods, anatomical features, and evolutionary advantages of each sub-class. For example, they will explore how monotremes lay eggs, how marsupials raise their young in pouches, and how placental mammals have developed highly efficient gestation systems that support complex development before birth.

Through this exploration, learners will come to understand how these adaptive features have contributed to the success of mammals as a group, making them the dominant vertebrates in many terrestrial ecosystems today. Topics such as parental care, social structures, specialised dentition, and advanced nervous systems will be examined to show how mammals have flourished across diverse habitats from deserts to oceans to polar regions.

By the end of the unit, learners will appreciate the evolutionary journey of mammals and the biological traits that have allowed them to thrive, survive, and become one of the most ecologically influential groups of animals on the planet.

Learners will develop a comprehensive understanding of the biological requirements of multicellular animals and how these requirements enable them to function effectively. They will explore how increasing complexity in body structure necessitates the development of specialised cells, tissues, organs, and organ systems, each with a distinct role that contributes to the survival of the whole organism.

They will explore the major organ systems, particularly those of mammals, including the circulatory, respiratory, digestive, nervous, muscular, endocrine, excretory and reproductive systems. Learners will study the structure and function of each system in detail, gaining insight into how each supports essential life processes such as nutrient absorption, oxygen transport, waste removal, movement, communication, and reproduction.

The unit will also highlight how organ systems interact and work together to maintain health and functionality. Learners will explore the concept of homeostasis, the body’s ability to maintain a stable internal environment despite external changes. They will examine key examples such as temperature regulation, blood sugar control, and pH balance, and understand the roles of feedback mechanisms in keeping these systems in balance.

By the end of the unit, learners will understand the interconnectedness of organ systems and the importance of internal regulation in maintaining life. This foundational knowledge will enable them to better appreciate how mammals and other multicellular animals survive, adapt, and respond to their environments.

Learners will gain a clear understanding of why animals need to eat, focusing on the role of nutrition in supporting vital life processes such as growth, energy production, tissue repair, and reproduction. They will explore how food is broken down and absorbed, and how different species have evolved to meet their nutritional needs through specialised feeding strategies.

This unit will examine a wide variety of animal feeding behaviours, including filter feeding, grazing, hunting, scavenging, and parasitism. Learners will explore how these strategies are influenced by an animal’s environment, anatomy, and ecological niche.

A key area of focus will be the comparison between herbivores and carnivores. Learners will study how herbivores such as cows, rabbits, and tortoises have evolved specialised adaptations to consume and digest tough plant matter. This includes features like flat grinding teeth, long digestive tracts, and symbiotic relationships with gut microbes. In contrast, learners will explore how carnivores such as lions, birds of prey, and snakes possess adaptations like sharp teeth, powerful jaws, forward facing eyes, and efficient digestive systems to capture, kill, and digest prey.

In addition to predator adaptations, learners will investigate the fascinating evolutionary responses of prey animals. They will explore a range of anti-predator adaptations, including camouflage, mimicry, warning colouration, speed, defensive behaviours, and the use of toxins or spines to deter predators. These examples will illustrate how the constant interaction between predators and prey has driven co-evolution, resulting in a diverse array of survival strategies in the animal kingdom.

By the end of the unit, learners will have a deeper appreciation of the complex and dynamic relationships between animals and their food sources, and how feeding and predation have shaped animal evolution.

Learners will develop a detailed understanding of both sexual and asexual reproduction in the animal kingdom, examining the biological processes, advantages, and limitations of each method. They will explore how asexual reproduction, such as budding, fragmentation, or parthenogenesis, enables some animals particularly invertebrates to reproduce rapidly without the need for a mate, and how this method contributes to population stability in certain environments. In contrast, learners will study how sexual reproduction involves the combination of genetic material from two parents, increasing genetic variation and promoting evolutionary adaptation.

The unit will explore the wide range of animal mating systems, including monogamy, polygyny, polyandry, promiscuity, and lekking behaviour, and how these systems are influenced by factors such as environmental conditions, parental investment, and reproductive success. Learners will examine examples across various species to understand how mating systems can differ dramatically between taxa.

In addition, learners will investigate how animals choose mates, often based on traits that signal health, genetic fitness, or the ability to provide resources or protection. Topics such as sexual selection, courtship displays, vocalisations, and pheromone signalling will be explored, along with the behaviours and strategies animals use to increase the likelihood of successful fertilisation from internal fertilisation methods in mammals and reptiles to external spawning in amphibians and fish.

The unit will also introduce the concept of intersexual conflict, where the reproductive interests of males and females diverge. Learners will examine how this can lead to an evolutionary arms race between the sexes, driving the development of complex behaviours and physiological traits, such as sperm competition, mate guarding, and selective ovulation.

By the end of the unit, learners will have a broad and insightful understanding of the diverse reproductive strategies found in the animal world, and how these strategies reflect the ongoing balance between cooperation and conflict in the pursuit of reproductive success.

Learners will develop a thorough understanding of the wide variety of animal habitats found across the planet, from forests, grasslands, and deserts to oceans, polar regions, and urban landscapes. They will explore the ecological and biological reasons why different animals choose to live in specific habitats, including the availability of food, shelter, water, suitable climate, and the presence or absence of predators or competition.

The unit will examine the factors that influence species distribution, such as temperature, altitude, soil type, salinity, water availability, and seasonal changes. Learners will analyse how these abiotic and biotic factors affect where and how animals live, breed, and feed. They will also explore how barriers such as mountains, rivers, and human developments can affect the range and movement of animal populations.

A key focus will be placed on how animals have adapted to survive in extreme environments. Learners will study adaptations in species living in hot, arid deserts, such as water retention, nocturnal activity, and burrowing behaviours, as well as those in cold, polar regions, such as thick fur, blubber insulation, and compact body shapes. They will also explore the adaptations of deep-sea creatures, such as bioluminescence, pressure resistance, and slow metabolism, to better understand how life can thrive in high-pressure, low-light conditions.

In addition, learners will consider the impact of urbanisation and how animals are responding to the increasing presence of human settlements. They will explore how some species have successfully adapted to urban habitats, using man-made structures for nesting, scavenging food from human waste, and adjusting behaviours to avoid people and traffic. This includes familiar examples such as foxes, pigeons, raccoons, and hedgehogs, as well as broader discussions about biodiversity in cities and the challenges of habitat fragmentation.

By the end of the unit, learners will be able to critically assess how different environments shape the lives of animals, how species adapt to survive in even the harshest conditions, and how human influence continues to reshape animal habitats and behaviours.

Zoology is the study of animals. It looks at how animals live, grow, move and behave. It also explores how animals are grouped, how they interact with each other and their environment, and how they change over time.

Studying zoology is important because it helps us understand animals and how they fit into the world. When we learn more about animals, we can protect them and their habitats. This is important for keeping nature in balance. Zoology also helps us understand how animals can affect people, such as through farming, disease, or the environment. By studying animals, we can find ways to care for them better and solve problems in nature and in our lives.
