Most dangerous ant

Who: Bulldog ant (Myrmecia pyriformis)
Where: Australia Australia

The most dangerous ant in the world is the bulldog ant (Myrmecia pyriformis) found in coastal regions in Australia. In attack it uses its sting and jaws simultaneously. There have been at least three human fatalities since 1936, the latest a Victorian farmer in 1988.
The bull dog ant earned its name because of its ferocity and determination during an attack. It is extremely aggressive and shows little fear of human beings, stinging a number of times in quick succession and therefore injecting more venom with each bite. In an attack, the ant will hold on to its victim with long, toothed mandibles, curl its body underheath and thrust its long barbless sting into the skin. On a few occasions this sting has been enough to kill adults within 15 minutes.

List of countries and islands by first human settlement

List of countries and islands by first human settlement Map of human migration , based on studies of mitochondrial (matrilinear) DNA. Though fossils of hominids have been found dating back millions of years, the earliest known Homo sapiens remains are considered to be a group of bones found at the Omo Kibish Formation , near the Ethiopian Kibish Mountains. Though believed to be 130,000 years old at their discovery in 1967, recent studies have dated them as far back as 195,000 years old. [1] From this area, humans spread out to cover all continents except Antarctica by 14,000 BP . According to a recent theory, humans may have crossed over into the Arabian Peninsula as early as 125,000 years ago. [2] From the Middle East , migration continued into India around 70,000 years ago, and Southeast Asia shortly after. Settlers could have crossed over to Australia and New Guinea – that were united as one continent at the time due to lower sea levels – as early ...
