✍️New blog post! Evolution Has No Plan: Why Organisms Don’t Rewrite Their DNA jenteottenburghs.wordpress.com/2025/12/18/e... The news articles on polar bears that are “rewriting their DNA in response to climate change” triggered me to write this blog post. Evolution has no foresight.

Several popular science websites reported that polar bears are "rewriting their DNA" in response to climate change. However, not one journalist took the time to critically evaluate the original study. I am not convinced. You can find my critique here. avianhybrids.wordpress.com/2025/12/17/a...

I have seen this claim popping up at several news outlets. When headlines report dramatic findings, the most reliable approach is to check the original scientific paper. I am not convinced by their "evidence". 🤔 Stay tuned for a blog post later this week. 😉
