Evoblog 4 Weblab Natural Selection

In this interactive lab I learned how natural selection works and what effects it. I first explored Flutter Bug island which consisted of make butterflies and birds that eat them. Some male Flutter bugs are more brightly colored despite the fact that being more camouflaged gives them a longer chance to live. I learned that brightly colored butterflies have more reproductive advantages over drab colored butterflies representing that they are more likely to pass their genes to their offspring even though they are more likely to be eaten. A drab butterfly may avoid being eaten however their offspring may not inherited the camouflaged color due to the fact that drab butterflies have less chances to pass down their genes. Finches too have differences in their beak size and in the food they eat. The beak size become appropriate according to the amount of precipitation and resulting seed size since it is their food. So their is a need for finches to have larger beaks than others because they need one other if the seed size changes in order to survive. Also finches that are more adapted to survive the environmental conditions are more likely to pass their genes to their offspring resulting in larger population. In next experiment dealing with mice I changes the environment of the mice and in the end I learned that mice that blended into their background the best were more likely to survive since they would be able to go undetected by cats and therefore to survive to pass on genes onto their offspring. The environment and natural adaptation changes the environment over time.
