The oldest fossils of footprints ever found on land hint that animals may have beaten plants out of the primordial seas. Lobster-sized, centipede-like animals made the prints wading out of the ocean and scuttling over sand dunes about 530 million years ago. Previous fossils indicated that animals didn't take this step until 40 million years later. {{cite journal}}: (עזרה)

The model shows that modern bees started diversifying at a breakneck pace about 114 million years ago, right around the time that eudicots—the plant group that comprises 75 percent of flowering plants—started branching out. The results, which confirm some earlier genetic studies, strengthen the case that flowering plants and pollinating bees have coevolved from the very beginning.

The oldest fossils of footprints ever found on land hint that animals may have beaten plants out of the primordial seas. Lobster-sized, centipede-like animals made the prints wading out of the ocean and scuttling over sand dunes about 530 million years ago. Previous fossils indicated that animals didn't take this step until 40 million years later. {{cite journal}}: (עזרה)

The oldest fossils of footprints ever found on land hint that animals may have beaten plants out of the primordial seas. Lobster-sized, centipede-like animals made the prints wading out of the ocean and scuttling over sand dunes about 530 million years ago. Previous fossils indicated that animals didn't take this step until 40 million years later. {{cite journal}}: (עזרה)
