4. Lowchen ($5,000 to $8,000) LÃ¶wchen means âlittle lionâ in German, a fitting name for this small dog with an impressive mane of hair and talent for agility. The breed is often given a âlionâ trim, too: clipped close to the skin at the hindquarters, with cuffs of hair around the ankles and a plumed tail.
Vestigial describes an organ or body part that continues to exist without retaining its original function, such as our appendix. It's most often used in biology to describe something that either didn't finish developing or has become, through evolution, pretty much useless.
The presence of an organ in one organism that resembles one found in another has led biologists to conclude that these two might have shared a common ancestor. Vestigial organs have demonstrated remarkably how species are related to one another, and has given solid ground for the idea of common descent to stand on.
