Life is a struggle for survival. Animals live under constant stress to obtain enough food to eat by being as well adapted to their environments as they can. Animals who are poorly adapted will, in times of hardship, starve, fail to reproduce, and eventually die out completely. Throughout Earth's history, life has constantly been taking new forms which are immediately tested for survival. When the climate or environment changes drastically, many animals who are poorly adapted for their new…

Ediacara approx. 550 million years ago Complex life starts to evolve. In the background are some frond-shaped Charnia. Nearby on the left are three Swartpuntia. The three white jellyfish-like organisms on the seafloor are Dickinsonia. On the seafloor are some sea anemone-like nemiana which may have had tentacles for catching food particles. In the foreground is a Kimberella, feeding on the bacterial mats by scratching with its proboscis. Another can be seen further back on the left. At…

Large butterfly-like insects known as Kalligrammatid lacewings, which fluttered through Eurasian fern- and cycad-filled woodland during the Mesozoic Era, have been extinct for more than 120 million years. But with new fossil analyses, scientists at the Smithsonian's National Museum of Natural History have discovered that these ancient lacewings were surprisingly similar to modern butterflies, which did not appear on Earth for another 50 million years.
