How do insecticides force evolution?
Widespread use of insecticides can lead to the evolution of insecticide resistance. In any population of insects there will be genetic variation ie individual insects are not identical; just like humans there are all different. Some individual insects will be more resistant to an insecticide than others. When an insecticide is used the individuals which are resistant will have a better chance of surviving. They will then pass on their resistance genes to their offspring, which will in turn have a better chance of surviving. In this way the resistance genes will spread through the population. This is an example of natural selection in action. See www.evolution.berkeley.edu/
During Darwin voyages to the Galoagos Islands he saw 13 species of finches How did the finches differ and what was Darwin explanation for the differences?
When Charles Darwin saw the different species of finches on the Galapagos Islands, he recored many hand drawn pictures of them. They differed in beak style. Some had beaks better suited for pecking bugs out of trees, while others were better at picking them out of the ground. His explanation for the differences was that they evolved over time to adapt better to their surounding and to have a greater chance of surviving. This was his theory of Natural Selection. Hope this helps. Lily When Charles Darwin saw the different species of finches on the Galapagos Islands, he recored many hand drawn pictures of them. They differed in beak style.

Why i cant remember what i am studding?
answ2. When your faculties are not behaving as they should, they have possibly been over exercised. They deserve a spell.This is not an unusual circumstance, and underlines the importance of not studying for overlong periods. Thus a more frequent study period of shorter duration will probably be better.
