Many asteroids of this type are now known; their orbits pass through the inner solar system and cross Earth’s orbit.
How much DNA do humans share with pigs?
Its small size makes it easy to handle and useful for medical research. The team looked at genes and protein domains that pigs and humans share. These are important targets for drugs. The researchers found the physiology of the two is 84 per cent similar at the genetic level.
