A study of earthworm genomes reveals rapid and dramatic genomic reorganization during land adaptation, supporting the punctuated equilibrium theory of evolution and challenging traditional Darwinian gradualism, suggesting that genome stability may not be as crucial as previously thought.
Earthworms often surface during rain, not to avoid drowning, as they can breathe through their skin in water, but possibly due to needing higher oxygen levels, mistaking rain vibrations for predators, or to move more easily on wet ground. Some species are more sensitive to low oxygen, prompting them to surface, while others may remain underground. Additionally, wet conditions may facilitate mating or migration. The phenomenon is also exploited in practices like 'worm charming,' where vibrations are used to lure worms to the surface.
A study published in Environmental Science and Technology reveals that bio-based fibers like viscose and lyocell, intended as eco-friendly alternatives to plastics, may pose greater risks to earthworms than conventional polyester fibers. The research found higher mortality rates and adverse effects on earthworm reproduction and growth when exposed to these bio-based fibers. The findings highlight the need for thorough testing of new materials before they are widely adopted as plastic substitutes, emphasizing the complexity of addressing microplastic pollution.
A study published in Environmental Science and Technology reveals that bio-based fibers like viscose and lyocell may pose a greater environmental threat than conventional polyester fibers, particularly to earthworms, which are vital for soil health. The research found higher mortality rates in earthworms exposed to bio-based fibers, raising concerns about their ecological impact. This highlights the need for thorough testing of new materials before they are widely adopted as alternatives to plastics, as part of efforts to address microplastic pollution.

The article delves into the decline of earthworm populations in Britain, a phenomenon that has largely gone unnoticed despite the critical role these creatures play in soil health and ecosystem functioning. Charles Darwin's extensive studies on earthworms are highlighted, contrasting the historical interest with the modern world's neglect of this issue.
