Please help!!!! I need to know how to do this and I need a complete example of what is written below. I am lost trying to do this!!!! Please do not take this if you can not give me a complete detail answer for this question. It needs to be complete, and I need to be able to get a true understanding of what is involved in this. Thank you
During the Paleozoic and Mesozoic eras several classes of vertebrates (Amphibia, Reptilia, Aves, and Mammalia) evolved and became established as basic grades of vertebrate organization. This evolutionary divergence resulted from effects changing environmental selective pressures had on random genetic variation of existing vertebrate groups. Extinct biological complexes never reappear during evolutionary progressions.
1. With these ideas in mind, I need to evolve a new mammalian order from an extant species of an existing order. I have to include selective pressures, new adaptations, and the new niche.
I need to describe in detail. I must have a name for this new order. The new order must still be a mammal and have all basic mammalian characteristics, and should differ from other mammalian orders only on an ordinal taxonomic rank level.
2. Then I need to evolve a new class of vertebrates from the order of mammals I have produced. I have to include selective pressures, new adaptations, and the new niche.
Then describe in detail the characteristics of this new class and name it.
The new class must still be a vertebrate and have all the basic vertebrate characteristics and should differ from other classes only on a class taxonomic rank level.© BrainMass Inc. brainmass.com October 24, 2018, 5:43 pm ad1c9bdddf
I have included an example in my attachment. You can do the same thing with any order and species that you choose. First you need to create some new niche or environmental change, and then examine what these new selective pressures may do to you animals and what adaptations will be beneficial. For whatever animal you choose, I would find out about what specific characteristics that animal already has, and then decide how they can be modified.
1. The first step is to choose an existing species in an existing order. For my example, I will choose the order Cetacea (the marine mammals, dolphins and whales) and the species of the bottlenose dolphin Tursiops truncatis. You can actually choose any order and species for this question.
Next come up with some scenario of change. Global warming has caused the ice caps to melt and thus the volume of the oceans has increased. This ...
The expert examines new mammalian order and new class of vertebrates. The taxonomic rank levels are given.
Dinosaurs and Birds do Interbreed
A new species has been discovered. The animal is a vertebrate, approximately 18-24 inches in length. Members of this species are covered in scales and are known to lay shelled eggs. Dissection has also shown that this animal possesses a four-chambered heart. Its skeleton is shown below, but the skull has been omitted. An image of the skeleton is shown below. A sample of the skull could not be obtained, but some characteristics of the skeletal structure of the head were observed: the skull lacks a sclerotic ring (bony ring which supports the eyeball), but possesses a secondary bony palate.
Identify this species' proper kingdom, phylum, etc and give this species a full classification. This may require a bit of extra research beyond the background materials. Justify your choice and also explain how you could use genetic evidence to verify your conclusion. (Note: The discoverer/ classifier of a new life form typically assigns a species name of their own choosing. Be creative!)View Full Posting Details
