What theory in the article does the author propose should take the place of “survival of the fittest”? Describe this new theory.

In today’s society, which theory do you think is more effective? Explain why you feel this way.

The article does not mention a specific theory that should take the place of "survival of the fittest." Therefore, there is no description of a new theory proposed by the author.

As the article does not provide an alternative theory, it is difficult to determine which theory may be more effective in today's society. Additionally, the question of which theory is more effective can be subjective and dependent on one's perspective. Some may argue that the concept of "survival of the fittest" still holds value in a competitive society, while others may argue for a more collaborative or compassionate approach for the well-being of society as a whole. Ultimately, it is up to individuals to form their own opinions and determine which theory they find to be more effective in the context of today's society.
