Why are most organisms sexual? The question of why most species reproduce sexually and others reproduce asexually has stymied biologists for years (particularly since asexual reproduction has many ...

1. Trade-offs between the reproductive and immune systems are predicted when resources are limited, but are difficult to measure. 2. We used ¹⁵N-labelled amino acids to directly compare protein ...

Ostracods, sometimes called seed shrimp, are nearly microscopic, aquatic organisms, inhabiting all types of marine and ...

Researchers led by the University of Cambridge have found the earliest example of reproduction in a complex organism. Their new study has found that some organisms known as rangeomorphs, which lived ...
