Charles Darwin: evolution of a scientist Welcome to The Manchester Museum and our new exhibition ‘Charles Darwin: evolution of a scientist’. In this exhibition, you will find seven graphic panels that illustrate chapters of Darwin’s life, complete with quotes from his autobiography. In the cases on the same side, there are related objects. The reverse of each panel uses objects to explore and explain scientific concepts and ideas. Use this guide to help you explore the exhibition and challenge yourself to find out more about Darwin, his life, his scientific methods and his discoveries. 1. Darwin’s Childhood ‘Charles Darwin always loved nature and collecting things’ Illustration board showing Darwin’s fascination with the natural world from an early age. The display case contains a collection a child might Illustration©Chrissie Morgan make. What are the different ways a collection can be organised? Out of the collection, which is the group of objects you would most like to collect? Why?
2. Student Days ‘Charles Darwin continued collecting and studying nature when he was at university and was keen to be recognised as an expert naturalist.’ Reverse display case: Explores 19th century natural history and collecting with a wide selection of beautiful and interesting natural history specimens, introduction to geology and the age of the earth (with fossils), Darwin’s impact and relevance today. Image©Steve Devine, Illustration©Chrissie Morgan What are the key variations between the different items in the display case? Pick one case and describe the variations you can see? During Darwin’s time most people thought the earth was 6,000 years old. What is the evidence on display that this is inaccurate? Illustration board: shows Darwin as a student at University of Cambridge. Darwin struggled at University and rather than attending lectures, he spent his time shooting, collecting beetles and observing nature. What is the book and page number that contained Darwin’s first published work?
3. Voyage of the Beagle ‘In 1831 to 1836 Charles Darwin travelled around the world in the HMS Beagle, a surveying ship’ Illustration board: During his voyage on the Beagle, Darwin witnessed a huge range of habitats, from tropical rainforests to deserts and volcanic bubbling mud that triggered his fascination of the natural world even further. Choose one of the habitats illustrated, think of an animal you might find there and identify the key adaptations that suit it to living in that Image©Steve Devine, Illustration©Chrissie Morgan environment. Reverse display case contains items Darwin saw and collected on the voyage of the Beagle An object is illustrated on the opposite side and also appears in the object case? What is it? What does it do and why is it important when sailing? Can you think of a similar bird to the Rhea that is found on a different continent? Can you identify some features of three different birds that Darwin collected whilst on the Beagle that made them suited to their different habitats? If you were Charles Darwin, what features of the mocking birds that you can see would make you think that they could be different species?
4. Back in London: ideas begin to grow After the Beagle voyage, Charles Darwin spent several years writing up scientific results of the expedition and thinking about evolution.’ Illustration board: Once Darwin had arrived home from the voyage, he moved to London and spent many years collecting his thoughts from what he experienced during his time on the Beagle. He read many books, observed closely and classified his specimens, kept ordered notebooks, met and talked to other scientists to collaborate and swap ideas. His work convinced him that evolutio existed, but he wanted to understand how it happened. Image©Steve Devine, Illustration©Chrissie Morgan Reverse display case contains items investigating ‘What is a Species?’ Use this image (wolf skull) and pick two other dog skulls. Can you identify the features that are similar between the three skulls and three that are different? Image©Steve Devine Like the butterflies and snails, can you think of another example that shows extreme variation within a species? From the evidence in this case how would you describe a ‘species?’
5. Working methods at Down House ‘Charles Darwin moved to Down House in Kent with his family in 1842. He set up a number of different methods to investigate evolution and natural selection.’ Illustrative board: Darwin moves to Down House in Kent with his wife, Emma, and his family. There he continued with his experiments, particularly on barnacles and began to collate his thoughts that lead to him write On the Origin of Species. What personality traits did Darwin have that helped him to be a good scientist? Which of your own personality traits do you think help you be a good scientist? Display case explores how science works and Darwin’s range of working methods. Describe the variety of methods that Darwin used in his research. Image©Steve Devine Who was Alfred Wallace? Why was he an important figure in Darwin’s life?
6. Publication of On the Origin of Species ‘Charles Darwin published his ideas on evolution by natural selection in November 1859, in a book that caused a scientific revolution’ Illustrative board: On the Origin of Species which detailed Darwin’s ideas on the theory of evolution by natural selection. The publication of this book caused a big stir. It was front page news and people talked about it in the street. You can see a first edition of On the Origin of Species in the display case. Reverse display case explores evolution and natural selection. In On the Origin of Species Darwin gathers the evidence that evolution has happened, based on observations of domesticated plants and animals, the fossil record, distribution of plants and animals and similarities in the organisation of their bodies. Why did the darker (melanic) form of the Peppered Moth survive better in Manchester in the 19th century? Pick one example from this display case of extreme adaption and natural selection between Peppered Moths, Pan Moths and leaf insects. What adaptation would be beneficial to it and allow it to survive? Identify the main differences in the Tiger Moths? How does this natural variation occur? Why do some males in some species contain bright colours and very decorative features and plumage? Why might this be an advantage? Can you think of some other examples in the animal world?
7. Aftermath/Impact ‘Charles Darwin is one of the most important scientists in history.’ Illustrative board: Throughout his lifetime, Darwin’s ideas became widely accepted and he was delighted and surprised to receive a spontaneous round of applause from the audience at a lecture he attended. It was a proud moment for him and confirmed that his work had made a significant impact to the scientific community. It was only after his death, when further discoveries were being made, that we realised how Darwins ideas were far beyond the time. Image©Steve Devine, Illustration©Chrissie Morgan Using the timeline, name five scientific discoveries post Darwin (1882-2009) that really ce- mented his theory of evolution as a scientific fact? How many books did Darwin publish? Can you name them? Considering the whole exhibition, which specimens do you think are the most convincing evidence for the theory of evolution by natural selection? Make an observational scientific drawing of a specimen of your choice from the whole exhibition
Further questions to consider post-visit: How did Darwin’s research methods differ from ones used today? Give some examples of technology available today that would have helped him. Why do you think On the Origin of Species had such an impact when it was published? Why is it difficult to identify different species? How can modern-day science help? What are the key steps in scientific methods? Can you describe them along with an example of an experiment you have carried out either at school or home? What is the different between a theory and fact? Can you give an example of both? www.manchester.ac.uk/museum http://learningmanchester.wordpress.com
