So this week in science class, my group and I were given an animal to research on. The animal we got was an Asiatic Elephant. Each of us got a separate piece of paper that was different. The paper I got was that I had to find facts about the elephants adaptations.
As we wrote the facts on our papers, we had to transfer them to a spreadsheet. The spreadsheet had columns for the REF number, my group and my initials, a link of where we found the facts.
When it comes to the greatest scientific discovery in history, I automatically think of Charles Darwin. After learning lots of great facts and interesting things that he did, I think he is the most achieved scientist.
If you didn't know, Charles Darwin discovered lots of exotic and unfamiliar animals that were formed by his theory of evolution; when he was studying finches which are small birds, he discovered that although those birds were from the same species, their had a difference in there characteristics.
The caterpillar is a twig mimic, varying in color between green and brown. On a historical note, it was one of the first animals to be identified as being camouflaged with counter shading to make it appear flat (shading being the main visual cue that makes things appear solid) in 1887.
It goes into the soil late in the season, where it pupates in order to spend the winter. The imagines emerge from the pupae between late May and August, the males slightly before the females (this is common and expected from sexual selection). They emerge late in the day and dry their wings before flying that night.
The males fly every night of their lives in search of females, whereas the females only fly on the first night. Thereafter, the females release pheromones to attract males. Since the pheromone is carried by the wind, males tend to travel up the concentration gradient, i.e., toward the source. During flight, they are subject to predation by bats. The males guard the female from other males until she lays the eggs. The female lays about 2,000 pale-green ovoid eggs about 1 mm in length into crevices in bark with her ovipositor.
