Introduction

Dodos, in order to understand the term dodos, Dennis ( 1998 ) suggested that it is of import to larn how they formed.And we can understand this throughthe term Taphonomy which is the survey of the conditions under which workss, animate beings, and other beings changed after decease and sometimes preserved as dodos. Research into these affairs has shown that fossilisation is a uncommon phenomenon. In order for dodos to organize, the organic structure must non be eaten or destroyed by eroding and other natural forces. Andrew ( 1997 ) define dodos as a old gifts from geologic yesteryear, marks and remains of ancient life things preserved in the earth’s crust, the preserved remains of past life on Earth. And this word has come from a Latin beginning from fossilis which mean dug up and that remains the cardinal feature of what people label dodos. Most people when they think of dodos they merely picture skeletons of animate beings, foliages and wood from workss all turned to lapidate they besides think of dodos asbeingmineralized bonesor shellsstored in museums. But they can besides be any remains or hints of earliest beings. They can be even footmarks, tunnels, or dramatis personaes of organic structures.

When new dodos are discovered, it is non ever clear as to which species they belong. There are two different, opposite attack to work out this job. They are normally known as the typological and the populationist point of views. Those who take thetypological attack believe that if two dodos look even a small different, they must be from two different species. This is an accent on minor differences. In contrast, those who use thepopulationist attack accept that persons in all populations of beings usually have at least minor differences. Therefore, when they come across dodos that are similar, but non indistinguishable, they group them into the same species ( Dennis, 1998 ) .

This assignment will discourse about what are fossils? How are they dependable? What can we larn from them?

WHAT ARE FOSSILS?

As Andrew ( 1997 ) define dodos as a old gifts from geologic yesteryear, marks and remains of ancient life things preserved in the earth’s crust, dodos are preseverd remains of past life on Earth, and they are any grounds of earliest life preserved in rock or other stuff. Fossils include casts, dramatis personaes, desertion stuff, tummy rocks, castanetss, footmarks, trails and tunnels. There are different sorts of dodos as follow:

  • dodos can include really old remains the existent organic structures of olden life, these can be occur frozen in glaciers or polar permafrost. They can be dry, mummified remain found in caves and salts beds, they can be preserved over geologic clip inside pebbles of gold and they can be sealed within heavy beds of clay, they are the ideal dodos about unchanged from their clip as a life but they are really rare.
  • Body dodos or mineralized organisms- disnour castanetss and putrified wood and everything like them are best known as sorts of dodos. These can include bugs and grain pollen as opposed to macrofossils where the conditions have been high. They make up most fossils image gallery. Body dodos are common in many topographic points.
  • The paths, nests, tunnel and fencings of earliest life things are another group called hint dodos or ichnofossils. They are highly rare but hint dodos have particular value because they are remains of an organism’s behaviour.
  • in conclusion there are chemical dodos or chemofossils remains that made up of more organic compounds or proteins originate in a organic structure of stone, include crude oil and coal, the dodos fuels are really great and widespread, illustrations of chemofossils. Chemical dodos are besides of import in scientific research into well- preserved sedimentary stones. For illustration the manner compounds found on, morden foliages have been detected in earliest stones assisting to demo when these beings evolved. A stone with dodos it can indicate out the rock’s comparative age, the type of being, what was follolized, the possible clime at the clip of follilization, perchance the distance the stone fossils has travelled, the composing of the stone, remotion of environment and other things depending on the type of dodos.

HOW ARE THEY RELIABLE?

Harmonizing to Dennis ( 1998 ) The fossils record provides grounds about the history of life and past environments on Earth. This besides shows that different groups of beings have changed over, the record of being that for a fact unrecorded in the yesteryear, it is really dependable, this is because it shows the existent remains of beings that live in the past and hence demonstrates for what really existed, fossils groundss is our apprehension of the history of life, on which this apprehension based on skeletons, roots, foliages, bark, chemical signatures, imprints, C residues, tunneling and trail Markss, petrified wood, footmarks, eggs, stomachic rocks, faecal affair and many others sometimes found in ice.

How dependable is fossils grounds ( 2014 ) when scientist survey dodos to sketch how the animate being died and how it evolved. The dinosaur castanetss, works dodo, sea life are fossil grounds that proves that there were animate beings long clip ago and can back up development. As dodos is grounds of a long clip ago life, dodos are dependable and can be trust worth because a dodos formed up when an animate being dies in a clay or other soft soil or deposit, finally the carnal decayed and leave the castanetss, however these castanetss get covered by soil, stones H2O and after some thousand old ages, the castanetss get together into sediment waiting to be discovered. This is where an idea of a works or animate beings is pushed into a soft deposit and hardens which shows the grounds.

What can we larn from them

Harmonizing to Dennis ( 1998 ) said that Fossils show us a great trade about earlier life forms.We are non merely larn about evolutionary procedures and tendencies, but we can besides reconstruct or reform organic structure forms. Most of import animate being dodos displayed in museums often are mineralized castanetss. From these skeletons research workers can regularly larn about gender, physical capablenesss, growing forms, life anticipations, andpathologies. For illustration, by analyzing musculus fond regard points on castanetss, it is normally possible to do conclusion footing on grounds about the size and form of musculuss. This can be an of import mark to understanding any of a assortment motions among animate beings. The comparative size, form, and place of eyes, nose, and ears on a skull can take to an apprehension of the importance and capablenesss of these different senses.

Dodos are among the most valuable beginnings of information about the Earth ‘s history. They tell us about the beings that lived on Earth from the clip of the oldest dodos, approximately 3.8 billion old ages ago, to the present. By analyzing dodos we can larn non merely about the animals and workss of the far-away yesteryear, but how they grew, what they ate, how they interacted, and many facets of their behaviour. Study of dodos has lead to of import of new understanding about how life evolved on Earth and about diseases, both earliest and modern. Fossils besides help us understand past climes, including ice ages and periods that were warmer than our present clime. Knowledge from the survey of dodos is assisting geoscientists understand planetary heating and its effects. By analyzing the terminal of group beings of the dinosaurs and many other life signifiers at the terminal of the Cretaceous Period, geoscientists have gained insight into the evolutionary deductions of impacts by infinite objects. Investigating the physical and chemical features of fossil beings that lived during times of utmost climatic alteration and helps us understand the deductions of the alterations we are doing in our ain environment. Fossils unwrap many facts that are highly interesting about the yesteryear. For illustration a plastic, Plastic comes from oil, which besides provides gasolene, gas heat, and many other necessities of present life. Dodos are one of the most utile AIDSs to happening oil, because oil tends to construct up in the pores of peculiar stone beds. Rocks of different ages have different dodos. Study of microscopic dodos brought up in french friess of stone during boring of Wellss has led to many major oil and gas finds. Besides, the oil itself is ensuing from dodo remains of earliest beings. ( Important of dodos, 2006 ) .
