Solution
It seems like you didn't provide a specific question. However, based on the statement you provided, it seems like you're referring to the process of evolution.
As populations undergo evolutionary change over time, there is a continual accumulation of changes in their genetic makeup or gene pool. This process can be broken down into several steps:
-
Variation: Within any population, there are variations. These variations can be in physical traits (like size, color, etc.) or in the ability to survive in specific environments.
-
Inheritance: Some of these traits are heritable, meaning they can be passed on from parents to offspring. These traits are controlled by genes.
-
High rate of population growth: Most species produce more offspring than can survive.
-
Differential Survival and Reproduction: Because resources are limited in any environment, the individuals with the most beneficial traits are more likely to survive and reproduce. This is known as natural selection.
-
Evolution: Over time, the traits that enhance survival and reproduction become more common within a population, leading to changes in the genetic makeup of the population. This is evolution.
This process continues over generations, leading to the development of new species.
