Sedentary farming began in, or around the fifth millennium B. C, as well as the domestication of cattle. Though there is some uncertainty, some archaeologists believe that iron metallurgy was developed independently in sub-Saharan Africa (possibly in West Africa). Archaeological sites containing iron smelting furnaces and slag have been excavated at sites in the Nsukka region of southeast Nigeria in what is now Igboland: dating to 2000 BC at the site of Lejja (Eze-Uzomaka 2009) and to 750 BC and at the site of Opi (Holl 2009). Smelting furnaces appear in the Nok culture of central Nigeria by about 550 BC and possibly a few centuries earlier. Ironworking technology allowed an expansion of agricultural productivity, and the first city-states later formed. Northern tribes developed walled settlements and non-walled settlements that numbered at 400. In the forest region, Iron Age cultures began to flourish, and an inter-region trade began to appear. The desertification of the Sahara and the climatic change of the coast caused trade with upper Mediterranean peoples to be seen.

Give him anything with Pluto or Donald Duck on and he will be very happy! Even the newer Disney stars like Handy Manny are very popular with him and I am happy that like all of their products, these characters are positive role models. You don't have to worry about anything your child may see when they are watching a Disney show! My secret wish and hope is that when he grows a little he will enjoy superheroes as much as I did at his age. I ate, slept and drank Superheroes practically when I was a young teen and really hope we can have this in common too. Batman and Superman were my favourites and I have already seen plenty of cool pictures that we could have a lot of fun together working on!
