Natural selection can act in three main ways on a character, such as body size, that is continuously distributed. Following graph represent fitness and their relative body size after the exposure of natural selection at different way? Which of the above population influence to which type of natural selection?

#Section 2: Evolution
Phylogenies can be used to test whether speciation has been sympatric or allopatric. Following figure shown a new species arises by allopatric speciation, its nearest relative will usually live in a different geographic area, such as in a nearby lake. Which of the following phylogenetic tree is correct?

#Section 2: Evolution
A graph shows the frequency distribution of the character (body size). B graph shows the relation between body size and fitness, within one generation, and the third the expected change in the average for the character over many generations (if body size is inherited). Which of the following correct figure for Average size with respect to time?
