The concept of evolution has always been connected with some notion of progress–natural selection pushing populations toward better and better adaptations to create "perfect organisms." How would you argue that evolution does not craft perfect organisms?

Solutions

Expert Solution

Evolution produces more perfect organisms this concept is not ture for every time as the if it is ture then why the nature creates the imperfect traits or species.

Think about a moth species during the industrial evolution in the England, there were two different types of species one have black colour wing and another one with light coloured wings.Before the evolution the light winged coloured moth were the more fit organism than the dark ones because they were able to hide or mixed with the tree bark colour but after the industrial evolution the polution of air cause change of the lichen colour on the tree bark for this the light coloured moths were more vernable to the predators while the dark coloured organism became more fit than the light ones.

So from the above caser we cpnclude that the natural selection pressure can not make prefect organism for the evolution if the nature was so much efficient then the light ones will be fittest and with time blacks wiuld have extinct, but it does not happened there were two different alles are present but in different artio and here the natural selection is just a variable circumstance which change over time.

I think that the allelic selection or the genetic factor is the most perfect for evolving more perfeect organisms.

Evolution by natural selection is an emergent property of the structure of DNA. According to the theory, individuals vary in form and behaviour in heritable ways, which leads to different survival rates of their offspring. True or False? The type of evolutionary relationship shown in phylogenetic trees is called horizontal gene transfer. Endosymbiosis is not an example of horizontal gene transfer.
