Final answer:
The sentence from 'The Human Genome Project' text is included to clarify the significance of the project's findings, indicating that there is more than just genes at work in determining individual traits and behaviors, and that human genetic similarity is greater than previously thought.
Step-by-step explanation:
The sentence "This means that there is more at work than just genes in determining why one person commits a crime and another is good at music or sports." is likely included in the text of The Human Genome Project to clarify the significance of the project's findings. The Human Genome Project has revealed that humans have far fewer genes than previously thought, which implies that factors beyond genes also play a significant role in determining individual characteristics and behaviors.
While genes are definitely a significant part of who we are, this sentence underscores the complexity of traits and suggests that numerous factors, including environment and personal experiences, contribute to the diversity of human behavior and talents.
Understanding that there are only about 20,000 to 25,000 functional genes in the human genome helps illustrate this complexity. By stating that the differences between humans are not due to a large number of genetic variations, the message is that the nature of human identity and behavior is intricate and cannot be solely attributed to genetics.
Moreover, this sentence also hints at the potential for genetic research to delve into the non-coding regions of DNA, which may have far-reaching implications for our understanding of genetics and biology.
