evolution

"What does it take to be a scientist in the field? Doug Emlen is a scientist. He studies beetles. Specifically, he studies the evolution of beetle weapons--how their horns and armor change to better suit them in different environments. This book starts with a mystery: Doug wanted to know why a particular type of beetle developed a massive evolutionary weapon. He wanted to know how these changes happened and what advantages these enormous weapons gave the tiny dung beetles. So, he went to visit. Part travel diary and part scientific exploration, Beetle Battles takes you deep into the South American rainforest to monitor beetles in their own habitat. Packed with color photographs, extensive back matter, and entertaining anecdotes, this book will make beetle fans out of all its young readers"--From the publisher's web site.

In 1862, naturalist Charles Darwin received a box of orchids, including the Madagascar star orchid. It had an 11.5 inch nectary, the place where flowers make the nectar that insects and birds eat. He determined that the only way this flower was pollinated was by a giant moth with an 11.5 inch proboscis. A moth with a long proboscis was cataloged on Madagascar in 1903, but it took almost ninety years to prove Darwin's theory. Includes information on the Madagascar hawk moth, the Madagascar star orchid, and pollination.
