Multiple sources report that some biologists are increasingly turning to Lamarckism, an older and previously discredited theory, to address observations that standard evolutionary explanations struggle to cover. The discussion centers on so-called “anomalies” in evolution—traits that appear in organisms in ways that do not fit neatly within existing accounts of how variation arises and is selected over generations. According to the cited coverage, the renewed interest is not described as rejecting evolution itself, but as updating or supplementing Darwinian frameworks to account for characteristics that show up at or near birth. The articles frame Lamarckism as a “return” rather than a new invention, suggesting that researchers are reconsidering mechanisms related to how organisms may influence traits that can then be passed on. Overall, the reporting presents Lamarckism’s resurgence as an attempt to provide explanations for specific biological patterns that current mainstream evolutionary theory cannot readily explain on its own, while noting that the idea has a complicated historical status in scientific literature.
Researchers revisit Lamarckism to explain evolutionary anomalies

- Some biologists are revisiting Lamarckism to explain evolutionary observations that standard explanations struggle with.
- The renewed discussion focuses on traits that can appear from birth or early development.
- Coverage describes Lamarckism as previously discredited but now reconsidered in light of certain anomalies.
- The reporting frames the work as an effort to update current evolutionary theory rather than dispute evolution itself.
Evolution is a fact of life. So much so that even the theory of evolution is evolving. Lately, a centuries-old discredited idea has been making a strong comeback. It helps us explain scientific observations that, according to standard evolutionary theory, should be impossible.
3 hours agoTo make sense of some characteristics that species exhibit from birth, you have to turn to an old discredited theory known as Lamarckism.
