Mutation is a change in DNA, the hereditary material of life. An organism's DNA affects how it looks, how it behaves, and its physiology  all aspects of its life. So a change in an organism's DNA can cause changes in all aspects of its life.
continuously variable transmission (CVT)=An automatic transmission that can change seamlessly through an infinite number of effective gear ratios between maximum and minimum values. Automatic transmission= Automatically change gear ratios as the vehicle moves, freeing the driver from having to shift gears manually.
A CVT is a type of automatic transmission that is very different from normal auto transmissions. CVT stands for Continuously Variable Transmission. The theory behind CVT is that there are infinite gear combinations. There are no set gears. <br /><br /> What I mean by this is your normal auto transmission will have 3,4, 5 up to 8 specific gears. The transmission finds the right gear and then move up or down to the next set gear depending on your driving needs.
