Its ubiquity in shows like CSI and Cold Case has increased public awareness to the point that many jurors in real-world courtrooms expect to see DNA evidence presented.
Further evidence for common descent comes from genetic detritus such as pseudogenes, regions of DNA that are orthologous to a gene in a related organism, but are no longer active and appear to be undergoing a steady process of degeneration from cumulative mutations. Further evidence comes from the field of biogeography because evolution with common descent provides the best and most thorough explanation for a variety of facts concerning the geographical distribution of plants and animals across the world. This is especially obvious in the field of insular biogeography DNA. Through news accounts and crime stories, we’re all familiar with the fact that the DNA in our cells reflects each individual’s unique identity and how closely related we are to one another. The same is true for the relationships among organisms. The DNA difference with gorillas, another of the African apes, is about 1.6%. Most importantly, chimpanzees, bonobos, and humans all show this same amount of difference from gorillas. A difference of 3.1% distinguishes us and the African apes from the Asian great ape, the orangutan. Collecting and analyzing DNA evidence tops the list of the lab's forensic toolkit, and its ubiquity in shows like CSI and Cold Case has increased public awareness to the point that many jurors in real-world courtrooms expect to see DNA evidence presented -- whether a case calls for it or not. Since then, DNA evidence has played a bigger and bigger role in many nations' criminal justice systems. It has been used to prove that suspects were involved in crimes and to free people who were wrongly convicted. This evidence explicates that evolution does occur, and is able to show the natural processes by which the biodiversity of life on Earth developed. Additionally, this evidence supports the modern evolutionary synthesis —the current scientific theory that explains how and why life changes over time. Further evidence comes from the field of biogeography because evolution with common descent provides the best and most thorough explanation for a variety of facts concerning the geographical distribution of plants and animals across the world. This is especially obvious in the field of insular biogeography Does DNA Evidence Prove Guilt? A Cold Case 25 years in the making suddenly yields results thanks to DNA testing that wasn't possible then, but does the evidence alone prove the suspect's guilt? 03:28. A Cold Case 25 years in the making suddenly yields results thanks to DNA testing that wasn't possible then, but does the evidence alone prove the suspect's g DNA, or deoxyribonucleic acid, is the molecule that makes up an organism’s genome in the nucleus of every cell. It consists of genes, which are the molecular codes for proteins – the building blocks of our tissues and their functions. The DNA difference with gorillas, another of the African apes, is about 1.6%. Most importantly, chimpanzees, bonobos, and humans all show this same amount of difference from gorillas. A difference of 3.1% distinguishes us and the African apes from the Asian great ape, the orangutan. In other words, your DNA is a combination of your mother's and your father's DNA. Unless you have an identical twin, your DNA is unique to you. This is what makes DNA evidence so valuable in investigations -- it's almost impossible for someone else to have DNA that is identical to yours. Since then, DNA evidence has played a bigger and bigger role in many nations' criminal justice systems. It has been used to prove that suspects were involved in crimes and to free people who were wrongly convicted. At the heart of DNA evidence is the biological molecule itself, which serves as an instruction manual and blueprint for everything in your body (see How Cells Work for details). A DNA molecule is a long, twisting chain known as a double helix. Since then, DNA evidence has played a bigger and bigger role in many nations' criminal justice systems. It has been used to prove that suspects were involved in crimes and to free people who were wrongly convicted.
