[Ans] What was inadvertently developed in the 1950s by Brazilian scientists?

Step 1 : Introduction to the question "What was inadvertently developed in the 1950s by Brazilian scientists?"

The Africanized bee is a hybrid species of the Western honey bee. These so-called “killer” bees were accidentally introduced into the wild by Brazilian scientists in 1956. The scientists were attempting to create a new hybrid bee in the hopes of improving honey production, when 26 swarms escaped quarantine and began to dominate the native honey bee. Africanized honey bees have been known to chase people for more than a quarter of a mile once they get excited and aggressive. They have killed some 1,000 humans, with victims receiving ten times more stings than the average honey bee.
