Antagonistic pleiotropy is not just theory—we can name the genes

This infographic illustrates the concept of antagonistic pleiotropy, showing how the same genetic factors (IGF-1 Receptor, Telomerase, p53) that promote beneficial rapid growth in early life can lead to detrimental outcomes like increased cancer risk in later life.

The same variants that help you grow fast as a child increase your cancer risk at 60. IGF-1 receptor variants, p53 mutations, and telomerase regulation all show the same pattern: benefits early, costs later. Williams proposed this in 1957. The molecular evidence arrived decades later.
