Don't take this the wrong way, but your oldest ancestor was not exactly a beauty.

Scientists on Monday said a tiny marine creature from China that wriggled in the seabed mud about 540 million years ago may be the earliest-known animal in the lengthy evolutionary path that eventually led to humans. It was a weird-looking beastie with a bag-like body and, for its size, a really big mouth.
