Peacocks
Natural selection
History
Peacocks are large, colorful pheasants of their tail feathers or coverts spread out in a distinctive train. It is more than 60 percent of the bird’s body length and their colorful eyes are markings of blue, gold, and red. Females believed to choose their mates by the size, color, and etc only by their feathers are trained. Peacocks are ground-feeders that eat insects, plants, and small creatures. There are 2 types of peacocks one of them is the blue peacock that lives in India and also Sri Lanka. The green peacocks can be found in Java.
Natural selection factors
Reproduction
According to experts on the peacocks the brightness of their feathers signals to females that the genes are high-quality.This would make the male peacocks ideal for reproduction.
Survival of the fittest
The survival of the offspring, the males are chosen first when it's time to mate. In reality, not all males have bright and large tails and this was especially true a few thousand years ago.
Genetic variation
In genetic variation in the males, the females will no longer benefit by discriminating among males on the basis of these traits.The peacocks have low heritability in the peacock's generation.There are two independent breeding it involves a total of 42 sires and 86 of their male offspring.
Analysis
Peacocks is related on natural selection because it explains that different modes of the selection.Mechanism of natural selection doesn't get enough attention in basic biology courses. The peacocks are involved with the animal kingdom and for the females and males to work with each other we need more and more peacocks in the world so they wont come instinct.
