Six-mark question
When answering this question you need to:- use good English, paying attention to spelling and punctuation
- organise your information clearly with an introduction, an explanation and a conclusion
(you can use a table for the explanation if you prefer) - ensure that you use the correct scientific terms.
Read the following article:
Where did our cats come from?For some time, it was thought that cats started living with people around 9,500 years ago. Archaeologists investigating the ancient ruins of a village in Cyprus found evidence of cats living in and around the houses.
However, a study by biologists published in 2007 suggests that the ancestors of our pet cats split from their wild cousins around 130,000 years ago. The scientists compared the genes of today’s domestic cats with genes from wild cats.
By looking at the similarities and differences in the DNA, the scientists discovered that pet cats are not closely related to today’s European wild cats. To their surprise, they found the closest genetic matches are with wild cats from the Middle East that lived over 100,000 years ago.
It is thought that people may have noticed that wild cats were helping them by reducing the numbers of pests spoiling crops and food stores. As a result, people took in some wild cats. The researchers believe that all today’s domestic cats are descended from just five Middle Eastern wildcats.
Explain the scientific evidence and methods used by the scientists to work out where domestic cats came from.
