What you will study in the Biological science-From Genes to Species  course at The Open University UK

Biology encompasses all aspects of the study of living things from their ecology and behaviour, physiology and anatomy, through to their cell biology and molecular composition. 

You will learn about biological processes operating at different levels - molecular, cellular, organismal and species – and explore key concepts and research methodologies in these areas. The module is presented as a series of eight topics, alongside which is a closely related Research Skills strand.

  • Topic 1: Species and Speciation

Here you will consider the enormous diversity of life on Earth and how it has arisen. You will learn about some of the difficulties in defining species as well as current thinking on the mechanisms of speciation.

  • Topic 2: Evolutionary Mechanisms

In this Topic you will study the mechanisms of evolution, examining the processes responsible for the diversity of living things. You will consider how variation in populations, which is necessary for evolution to occur, is studied and how it changes over time.

  • Topic 3: Origin of Variation

With the exception of some viruses, the genomes of all organisms on Earth are composed of DNA. Changes in DNA in individuals are the source of variation in a population, which allows evolution to occur. Here you will learn about how and why changes in DNA occur, and the effect of environmental influences on variation. You will also engage with case studies that illustrate how the molecular basis of variation is studied experimentally.

  • Topic 4: Genomes and genome evolution

The genomes of different species differ considerably in their content and structure. Considering that all life on Earth is believed to originate from a common ancestor which existed over 3.5 billion years ago, a great amount of genome evolution must have occurred to give rise to the diversity of present day species. 

  • Topic 5: Gene expression and its control

Whilst the characteristics of an organism are determined by its genome, the expression of its component genes varies. Whether or not particular genes are expressed in a particular cell, and the level of their expression, are determined by a variety of control mechanisms. 

  • Topic 6: Controlling cell behaviour

All organisms, whether unicellular or multicellular, need to respond to their ever-changing environment in order to survive and flourish. In this topic, you will learn about some of the fundamentals of cell signalling - how cells detect and respond to physical changes and chemical cues occurring around and within them. 

  • Topic 7: Life and Death of the Cell

This topic takes a look at fascinating biological processes that occur at the beginning and end of the life of a cell. Cell death is a crucial aspect of life, and without cell death organisms would not develop or function correctly. Here you will focus largely on a form of programmed cell death known as apoptosis. 

  • Topic 8: Development, morphogenesis and ageing

In this topic, you will move from considering processes purely at the cellular level to relate these processes to what happens at the level of the whole organism. You will begin by focussing on the mechanisms that orchestrate embryonic development in multicellular organisms, before turning to the factors that influence the life span of different organisms, and to those that result in their biological ageing.
