Study reveals flexibility in meiosis across evolution

A study from the Stowers Institute for Medical Research, published in Science Advances, reveals that the molecular machinery guiding meiosis—the process essential for human fertility—is more flexible than previously thought. Researchers found that while sea anemones share synaptonemal complex proteins with humans, these proteins often perform different functions, indicating rapid evolutionary change.

Lead researcher Dr. Stefanie Williams observed that disabling specific proteins like sycp1 and syce2 caused female sterility in sea anemones while leaving males fertile. These findings suggest that the architectural functions of these proteins have evolved significantly, offering new insights into how meiosis-related errors may lead to infertility and birth defects.
