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.
Adaptations can take many forms: a behavior that allows better evasion of predators, a protein that functions better at body temperature, or an anatomical feature that allows the organism to access a valuable new resource  all of these might be adaptations.ne example is vestigial structures. A vestigial structure is a feature that was an adaptation for the organism's ancestor, but that evolved to be non-functional because the organism's environment changed. Fish species that live in completely dark caves have vestigial, non-functional eyes.
