What Is Archeology?

Decent Essays
Throughout time, archeology has evolved. Archeology has adapted specialized tools and uses new discoveries to aid their sight into the past. One of those advancements is the discovery of DNA. The discovery of DNA has greatly enhanced our ability to analyze individuals in the field of archeology. I will out line the discovery of DNA and initial integration into the field of archeology, the use in present day archeology, the advancements and refinements of DNA testing, and the future applications of DNA testing.
DNA is short for Deoxyribonucleic acid. DNA is the building block for all carbon based life forms that we know of. DNA caries a set of instructions for all living beings, how tall, how short, color, size, and so on. Thus it is indispensible

DNA can do a multitude of helpful things. DNA can help us to understand how modern humans evolved, the migrations of various peoples over time, identify individuals, and determine the origins of domesticated animals and plants. Normally ancient DNA molecules are sparse and fragmented and preserved tissues are so rare, scientists have little hope of finding and analyzing it. However, breakthroughs and advancements have made it possible to analyze more fragmented material: the polymerase chain reaction, or PCR, a method for copying any piece of fragmented DNA. The last is the successful recovery of DNA from preserved hard tissues, bones and teeth, which are durable and usually more available. This means that archeologists are able to more successfully recover ancient…show more content…
One of the newest of DNA testing methods is know as the Short Tandem Repeat method. What is it? Well, The human genome consists of fixed and repeated DNA sequences. The repeated sequences come in different lengths and are categorized by their corresponding length of the base repeating parts, meaning the amount of adjoining repeat units, and overall length of the repeat piece. The DNA regions with short repeat units, usually 2 to 6 bp units in length are known as Short Tandem Repeats or STR. STRs are found covering the inside of the chromosomal structure. STRs have numerous benefits that make them great for human identification.
STRs have become a main practice in DNA analysis due to the easily amplifiable structure. Enhancement methods such as polymerase chain reaction or PCR. PCR products for STRs are generally similar in amount, making analysis easier for analysis and amplification. An individual gets one copy of an STR from each of its parents that may have similar repeat sizes. The amount of repeats in STR markers can be a relatively high variable among an individual, which make STRs an effective strategy for identification of an
