EPS SCI 3 Lecture Notes - Lecture 9: Horizontal Gene Transfer, Sexual Reproduction, Natural Selection
Document Summary
Evolution won"t proceed if there isn"t changes in the environment. Environmental and genetic interactions in the evolution of life. The life we see today is very different from common ancestor. The reason why children can be different from their parents is because . This allows for evolution to take place. Genetic diversity: ex. imagine that there is . We have green and orange beetles because of genetic mutation. Time: when birds eat all the green beetles, that leaves all the orange beetles. Orange ones get a change to reproduce increase orange population. Cell division and reproduction. how can genetic information be transferred from the. Each cell has their own genetic information. Ex. genetic information of resistant bacteria can give this information to other themselves bacteria can form resistance to antibiotics. This is the key to form variation in genetic information. Ex. when sperm produced doesn"t have same original information. Also in cell division, information can be copied wrong.
