1995

9).- Electronic Cash

From barter to currency, the currency the ticket, the ticket to... piece of plastic. Wow Is it my idea, or a human being reinvented increasingly value systems increasingly less tangible? This new way of payment was invented in 1995 or it is said that before. However, electronic money has been a haven for some, and a constant nightmare for most preferring to pay cash. The feeling of "immortality money" that provides a credit card is very tempting, at least until the bank statement arrives later this month and people are and shock because of what they have to pay once. Some still prefer to hold cash in your pocket, but there is no doubt that the world likes increasingly dig.

1997

10).- The first successful cloning

In 1997 would give the greatest advance in this field, and perhaps one of the biggest steps of humanity - the first successful cloning of an adult mammal, a sheep named Dolly, from one of its cells. This new research may demonstrate that cloning is an effective way to create herds of cows or sheep that could serve as drug factories. In the very near possibility of cloning humans, has sparked worldwide controversy: Is cloning a wolf in sheep pielde? Today, society is not very convinced by the usefulness of this new discovery, as it can or is used for human cloning, which would be frowned upon by people.
