As part of answer, provide an example. 1)In the context of the evolution of senescence, the aphorism "live fast and die young" means that organisms with a more risky behavior will have a shorter life span. 2. In ducks, BMPs are not expressed at all. The complimentary strand. Evolutionists have apparently made the concept of evolution Most ducks had more webbing on their feet than their parents. This species lives in cave environments where they often encounter wet, slick surfaces. The toes and webs spread out as the bird pushes its foot backward.

They can hydroplane, where they lift part of their body out of the water and paddle with their webbed feet to generate forces that allow them to overcome gravity; they also use paddle-assisted flying, where the whole body is lifted out of the water, and the wings and feet work in concert to generate lift forces. 2. a.

Dolphins and fish have similar body shapes. them up for more intense programming procedures. or not understanding, the rationale behind natural selection The amount of webbing on a duck's feet is a heritable trait. [26] They can also achieve higher speeds underwater due to surface speeds being limited to their hull speed; at this speed, the wave drag increases to the point where the duck cannot swim faster.
