Extreme CO2 greenhouse effect heated up the young Earth

New research suggests that high CO2 levels in the atmosphere may have warmed the young Earth's climate, accounting for apparent anomalies such as hot seawater temperatures above 70°C. The study proposes a plausible explanation for these phenomena, indicating temperatures closer to 40°C when considering ocean composition changes.

Evolution: Building blocks of life

Researchers at Ludwig-Maximilians-Universität München have identified a plausible reaction mechanism for the production of key components of RNA under conditions similar to those on the young Earth. The discovery validates a pathway that could explain how chemical evolution proceeded before the formation of the first cells.

How anti-evolution bills evolve

An evolutionary biologist analyzed 65 anti-evolution bills, finding they share traits with each other and evolution itself. Creationism has evolved stealthily, using tactics from human cloning and global warming debates to influence education policies.

High school biology teachers reluctant to endorse evolution in class

A recent study found that only 28% of high school biology teachers implement National Research Council recommendations on evolution, while 13% explicitly advocate creationism. The remaining 60% use strategies to avoid controversy, undermining scientific literacy and legitizing creationist arguments.

St. Bernard study casts doubt on creationism

Researchers at the University of Manchester examined St Bernard skulls over 120 years and found features that became more exaggerated as breeders selected for desired physical attributes. This suggests sustained evolutionary change under known selective pressures.

Intelligent design: The new 'big tent' for evolution's critics

The intelligent design movement argues that life's complexity demands a knowing designer, potentially altering the way science is taught in schools. While differing from scientific creationism, its agenda to weaken or eliminate evolution's teaching in public classrooms remains ambitious.
