The course discusses patterns of diversity, ecology, and evolutionary biology. Emphasis is placed on the tree of life and how its members are distributed and how they are all inter-linked. The smallest bacteria to the largest insect are discussed with everything in between. The focus is on the evolutionary process of each species and exactly how they have changed over the years. The reproductive lifestyles of the organisms are also discussed. Perfect for careers or degrees in science, healthcare and medicine, animal care & the environment.
There is a great amount of biological diversity in this world and our course in biology aims to be just as diverse, providing for a comprehensive knowledge of the interconnectedness of the organisms. The story of this course begins just as the story of the biodiversity and organisms began, with evolution. Students start with an understanding of the principles of evolution, natural selection, genetic resistance, and mutation.
Further ahead the course explores the origins of species and subspecies, their history and evolution, along with a detailed analysis into protists and their relevance for food growth. Plants form a huge part of the ecosystem and the students will explore them in detail in this course. Due to the interrelated network between various organisms and its implications for sustaining life on earth, plant diversity and plant adaptation present an interesting aspect.
Towards the end of the course, students will have gained a strong understanding of natural processes, the development of various multicellular organisms, and will have prepared them for choosing a direction in the specialized field of biological studies.

Biologists are scientists that study all types of lifeforms—animals, plants, and the ecosystems they live in. They work to understand how plants and animals have evolved across history, research how living things adapt to environmental changes, and work to maintain viable ecosystems that support lifeforms.
