Researchers have discovered tangible evidence of this interaction in fossils of perforated shells, revealing a dynamic ...

这些贝壳化石属于一种早期灯壳亲缘动物 Lapworthella fasciculata，发现于现在的南澳大利亚弗林德斯山脉。它们在地球上最早的生物多样性大爆发--寒武纪大爆发--中生活和死亡。 长期以来，研究人员一直对如此迅速的生命多样化是如何发生的感到着迷。众所周知 ...

Some of the holey shells became fossilized, and now tell us the story of the earliest known battle between predator and prey that influenced both species' evolution. "This critically important ...

A biologist explains what to focus on if you’re designing a garden with pollinators in mind − and what you don’t need to worry about.

An evolutionary arms race is like a continuous competition between two species, where each one constantly evolves to outsmart the other.

This suggests that a microevolutionary arms race was in place, with L. fasciculata finding a way to fortify its shell against predation and the predator, in turn, investing in the ability to ...

Examples of Lapworthella fasciculata shells (under scanning electron microscope) from the Mernmerna Formation, Flinders Ranges, South Australia, showing holes made by a perforating predator.
