Taxonomy, Plants & Animal Evolution

1. What is taxonomy?

2. Look at plants and animals. Select a plant and an animal and see how it evolved up the Tree of Life from the beginning of time to the present.

3. How did this species change over time? How did it start out and how did it evolve.

4. What were the factors in its 'branching' out?

5. How does this reflect the biodiversity of life over time?

6. How do plants, animals and fungi work together? Each has a purpose and provides something to the other.

7. What are three treasures or riches of the rainforest and what do they provide?

8. How do we safeguard this biodiversity?

1. Taxonomy is " a hierarchical system developed by Swedish scientist Carolus Linnaeus for classifying and identifying organisms." (1) It has two main features in Linnaeus taxonomy. The first feature is binomial nomenclature, which mean that the organism scientific name is composed of the genus name and the species name. The second feature of Linnaeus's taxonomy system is the seven major categories: Kingdom, Phylum, Class, Order, Family, Genus, and Species.

2. Insect group: In the beginning, the "first insect lineages are the earth bound silverfish and their relatives." These are tiny insects that have no wing and form during the middle Devonian. (4) This insect group then evolved to the next group that have wings during the Cambrian explosion in the middle of the Carboniferous. (4) In the end of the Carboniferous period, there were new insects that developed into distinct order. During the Permian, a new insect form appeared, such as the Psocoptera, Homoptera, Hemiptera, Mecoptera, and Coleoptera. (4) The dragonflies and mayflies are considered " the first winged insects. The wings of these two groups cannot be folded across their backs, and belongs to a group called Palaeoptera, which stand for "old wings". The insect group called Holometabola are group of insects that undergo complete metamorphosis like laval, pupal , and adult stages. The holometabola includes the four group: wasps, beetles , moth and flies. The wasp and bee were the first lineage of holometabolan to evolve. (2) The Permian extinction killed all of these insects and more were wiped out during the Triassic and Jurassic period.(4) There were survivals, like the Neuroptera, Mecoptera, Diptera (flies) and Coleoptera that evolved into the modern families of insects in modern times.
Flies - Researchers believe that mosquitoes and flies are related; that mosquitoe branched off the same evolutionary lineage on the tree of life as flies about 220 million years ago. The earliest form of fly lineage is the rare families ...
