Politics can have unintentional evolutionary consequences that may cause hastily issued policies to cascade into global, multigenerational problems, according to political scientists.
“Most western democracies look at policies as if they are bandages, we fix what we can and then move on,” said Pete Hatemi, associate professor of political science, Penn State. “But we need to consider generational policies so that we can fix what we can now, but also be prepared for what comes next.”
The researchers said that there is an interaction between political and cultural forces and evolutionary results. Genes can shape culture and political institutions, which in turn can shape biology and physiology, passing on certain traits to future generations. The environment’s influence on adaptation and how it changes biology is better known and often easier to observe, said Hatemi, but the way culture can affect gene expressions in future generations is often harder to show and may take longer to reveal itself.
