Scientists have pinpointed the 'pace' and 'shape' of life as the two key elements in animal life cycles that affect how different species get by in the world. The findings have important implications ...

Neutral patterns of population genetic diversity in species with complex life cycles are difficult to anticipate. Cyclical parthenogenesis (CP), in which organisms undergo several rounds of clonal ...

Epaulette sharks can reproduce without any measurable increase in energy use, stunning researchers who expected egg-laying to be costly. Scientists tracked metabolism, blood, and hormone levels ...

Occasionally, friends have asked me about the life cycles of plants, so here I will attempt to summarize them, in the context of plant evolution. I set the stage by describing the basic pattern of ...

Researchers studying the malaria parasite Plasmodium falciparum have discovered a previously unknown stage in its life cycle that appears to be crucial for reproduction. This is important because ...

There are two basic life-cycle patterns among animals. Many animals have complex life cycles with two or more very distinct stages; metamorphosis is the usual term for the often-radical changes that ...
