David Kennedy Evolution Group 4 9/22/13 Lab 1: Insect Diversity and Evolution Introduction: Insects dominate the Earth with vast diversity and number of species. They are arthropods that have articulate appendages‚ a hard exoskeleton‚ compound eyes‚ and an open circulatory system with a dorsal heart. Insects have large populations in many habitats‚ even urban environments such as Chicago. Insects are close relatives to Myriapoda‚ Chelicerata‚ and Crusacea organisms (Hoffmann 63). They are incredibly

Myiasis is classified into many types of the cutaneous myiasis. The three main types of the cutaneous myiasis are wound myiasis‚ furuncular myiasis which start when the larva remains in a single spot that causing a boil-like lesion‚ and the creeping myiasis which start when the larva burrows inside the skin.[4] The nosopharyngeal myiasis which infect the nose‚ pharynx‚ and sinuses. The opthalmomyiasis which involved the eyes‚ periorbital tissues‚ and the orbits. The intestinal

The Forest Tent Caterpillar goes through 4 different life stages‚ the egg‚ larva‚ pupa‚ and adult. The egg has an incubation time of 10 months which begins in July and goes to early spring. When a new egg mass is formed‚ it has a shiny and dark brown appearance compared to old egg masses that are dull‚ lighter‚ and a whitish color

The discovery of the Comb jelly which was the first animal fossil was a shocking and unexpected event to most scientists in the world. Scientists had a specific view about evolution. They thought that organisms evolve from a simple state to a more complex state. But that was not the case for the comb jelly which unlike what scientist thought was a very complex specie. It was so complex that it had a nervous system and tissues. But that was not the only misconception that they had to face. Another

and short life cycles‚ they are ideal for the study of genetics. The generation takes about 10-15 days to be complete depending on the temperature. Ideal temperatures range from 20-25°C‚ where 25° reduces the days it takes for an egg to turn into a larva. However‚ exposure to temperatures significantly higher or lower may result in death or imparities. There are several ways to distinguish the sexes. Females are generally larger than males. Females have seven segments in

Male inseminate female for internal fertilization‚ and then the female lays egg‚ about 100 eggs per day or 500 eggs within 2 weeks. It takes about 24 hours for an egg to hatch into a larva. The third instar stage‚ the larva will crawl up the sides of the jar‚ attach itself to a dry surface and form the pupa. After about four days in the pupal stage‚ an adult fly emerges. The life cycle takes only 10 days for this type of fly. In addition‚ Drosophila
