孔雀蜘蛛有一百多種不同的品種，而大多數動物只有五到十個品種。

研究人員現在認為，這可能是由於蜘蛛遺傳密碼中的一個神秘部分造成的。

孔雀蜘蛛是一種微小的蛛形綱動物，每隻大約只有米粒大小或更小，遍布澳洲各地。

他們決定研究蜘蛛的基因——構成所有生物的訊息，並包含生物如何生長和運作的指令。

桑格研究所的研究小組認為，答案隱藏在蜘蛛遺傳密碼的一個神秘部分—「暗 DNA」中。

專家認為，這種「暗 DNA」可能在蜘蛛演化過程中發揮重要作用，也是它們如何適應不斷變化的環境形成新物種的原因。

科學家現在想要比較每個物種的結果，希望找出哪些基因決定了每個特徵，並最終找出為什麼孔雀蜘蛛有這麼多不同的類型。

Scientists say they've begun to better understand why there are so many varieties of a colourful, dancing Australian spider.

There are over a hundred different species of the Peacock spider, when most animals have only five or ten varieties.

Researchers now think this might be due to a mysterious part of the spider's genetic code.

One theory is that this may help it to adapt to changing environmental factors and form new species.

Peacock spiders are tiny arachnids - each one is roughly the size of a grain of rice or smaller - that are found across Australia.

They get their name because of the brilliant colours that males have on their abdomen, which they show off when they dance.

They create a drumming sound with their feet and move in rhythm while displaying their amazing patterned bodies.

What makes these creatures even more remarkable is how varied they are in their appearance, songs and dance moves.

Researchers at the Sanger Institute in Cambridge decided to take a closer look at the colourful spiders and why there were so many different types.

They decided to study the spiders' genetics - the information that makes up all living things and contains instructions for how the living thing will grow and function.

The team at the Sanger Institute think the answer lies in a mysterious part of the spider's genetic code - known as 'dark DNA'.

Experts think that this 'dark DNA' could play a big part in how spiders evolve and the reason behind how they may be able to adapt to the changing environment to form a new species.

Scientists now want to compare the results of each species, in the hope of finding out which genes are responsible for each characteristic and ultimately why there are so many different types of Peacock spider.
