yes they are called ammendments
This is an entirely subjective question but... I'd say that the US Constitution is, in and of itself, entirely inert. It has been the US Supreme Court that has bent and molded it through various interpretations through the years.
The Constitution has been ratified and taken into effect at March 4, 1789. As of the year 2012, the U.S has been using the Constitution for 223 years (2012-1789 = 223).
The fact that the United States Constitution can be amended and changed as necessary has allowed it to adapt to fit the need of any legal issue so far. =D

There is an amendment process for changing the Constitution. So far there have been 27 amendments. The Supreme Court can in effect change the Constitution by its decisions. Indeed the changes made by the Supreme Court are often more radical and far-reaching than those made by amendment .

Plants that are thousands of years old have adapted to be able to survive the earth's changed conditions. Most of the plants that have been able to survive are trees. Scientist have been successful growing seeds that are thousands of years old to regenerate the plant. The oldest seed to be successful is the 32,000 year old Silene stenophylla.
Mandrills have been known to survive in captivity for up to 31 years.
