Scientific names In Science, universal names are used to avoid confusion and help everyone identify animals and plants quickly and consistently. Carl Linnaeus, was the first person to do this scientifically, and for this reason he is known as ‘the father of modern taxonomy’. In the 18th century, he devised a universal way to designate the species: the Scientific Name. Scientific names use two words. The first is the Genus, and the first letter is always written with a capital letter. The second is written in lower case. (Italics are always used for this.) Both words then form the species’ name. For example, in any part of the world, the Iberian lynx is known as the Lynx pardinus and the donkey is an Equus asinus!

Lynx pardinus

Equus asinus

1 Think about and answer the questions.

1. Why did Linnaeus invent the system of classification?

2. In your opinion, why was a scientific system of classification necessary in the 18th century?

3. Which tools do modern scientists have to classify living things that Linnaeus did not have?

2 Invent and draw an imaginary living thing. Then classify it according to the Linnaean system.

Biodiversity Biodiversity is the variety of life on Earth in all its forms. It is the result of evolution, a slow process which began with the first life forms and still continues today. Species change and adapt to the environment. Biodiversity varies tremendously throughout the world. It is influenced by climate and habitats, amongst other things. Polar regions generally have fewer species, and so have less biological diversity. The Atlantic Forest in Brazil has about 20,000 plant species, 1,350 vertebrates and millions of insects, and so has great biological diversity. Some regions have lost some of their biodiversity because plant and animal species have been severely reduced or even destroyed by deforestation, uncontrolled hunting and fishing, pollution and other factors.

1. Are rocks and minerals included in biodiversity? Explain your answer.

2. What is the name of the process which began with the first forms of life?

3. Why does biodiversity vary throughout the world?

4. What factors can affect and reduce biodiversity?
