Today, many studies have shown that there is not a link between vaccines and autism. Unfortunately, there are still some people that refuse to have their child vaccinated for fear of him or her developingThe fossil (left) was unearthed in Wisconsin in 1985.

Scientists studying fossils collected 35 years ago have identified them as the oldest-known scorpion species, a prehistoric animal from about 437 million years ago. The researchers found that the animal likely had the capacity to breathe in both ancient oceans and on land.

The discovery provides new information about how animals transitioned from living in the sea to living entirely on land: The scorpion's respiratory and circulatory systems are almost identical to those of our modern-day scorpions—which spend their lives exclusively on land—and operate similarly to those of a horseshoe crab, which lives mostly in the
