Puebloan and Unangan). The Egyptians, Peruvians and Puebloans were all farming societies but the Unungans of Alaska were hunter-gatherers.
    Scientists scanned the mummies using the latest technologically advanced equipment and they found that all the mummies showed signs of atherosclerosis (the hardening of the arteries ) and cancer. Critics of the Paleo diet say that this proves it has no benefit. However, defenders of the diet believe that the study does not prove anything completely.
    As with all diets, the Paleo diet has its supporters and its critics . However, it won’t be long before the next diet idea becomes popular.  Worrying about what we eat is a big part of western society, although cavemen had other problems to think about, such as catching their next meal. How times have changed!

    Burmese pythons in Florida, parrots in the UK, camels in Australia – these are all examples of invasive species. An invasive species is any species of plant or animal, which is present in an ecosystem where it is not native .  This article will take a look at some invasive animal species and look at some of the factors which brought them to their new homes.
    The phenomenon of animal species living in new places has increased hugely in the last century.  Invasive species are either introduced by humans on purpose (e.g. for hunting or to try and control another animal species) or accidentally (e.g. when animals escape and begin to breed in the new environment).
    One example of an escaped invasive species is the American mink in the UK. The mink is a medium-sized member of the weasel family. The first American mink were brought to British fur farms in 1929 and some escaped. All wild mink in Britain today are descendants of these escapees. Their natural colour is a dark brown, appearing almost black in some light.  Mink have damaged the UK ecosystem because they hunt and kill many animals, such as: water voles, kingfishers (a rare type of bird) and crayfish (a kind of small lobster).
    Another example of an escaped invasive species is the Burmese python in Florida, USA. Burmese pythons are native to many parts of Southeast Asia and southern regions of China. They are endangered in Southeast Asia where they are hunted for their skins and captured for sale as exotic pets. They can grow to 5.5 m long and weigh over 91 kg, making them one of the world's largest
