Why do tree frogs lay their eggs on the ground?

When it comes to laying eggs, tree frogs have some unusual habits. Instead of always laying their eggs on tree branches where they usually live, they often lay their eggs on the ground. But why would a tree frog do this, ...

Why eukaryotes, not bacteria, evolved complex multicellularity

Prokaryotic single-celled organisms, the ancestors of modern-day bacteria and archaea, are the most ancient form of life on our planet, first appearing roughly 3.5 billion years ago. The first eukaryotic cells appeared around ...

Gene flow in giraffes and what it means for their conservation

Giraffes are a beautiful and powerful example of what adaptive evolution can achieve. However, in recent years, they have attained notoriety for a completely different reason: it has been suggested that instead of one giraffe ...

Defensive cage architectures in herbivore-driven ecosystems

Dense branching and spines are common features of plant species in ecosystems with high mammalian herbivory pressure. The combination of dense branching and spines is likely to produce the most effective herbivore defenses, ...
