Answer:

Because if your DNA fingerprinting is not at the crime scene it means that you have no involvement in the crime, but if your DNA fingerprinting is at the crime scene, it does not necessarily mean that you are responsible for the crime.

Explanation:

Genetic fingerprint is the characteristic of DNA that allows differentiating each individual, related or not, from any sample that contains genetic material.

In addition to the use for paternity identification, the use of genetic fingerprint recognition is also widely used in forensic science. Currently what is a standard procedure, the collection of genetic material from crime scenes has, for over 20 years, been helping investigators to decide whether DNA samples from suspects and those found at the crime scene come from the same individual. However, a genetic fingerprint is more effective at proving someone's innocence than guilt. That's because if your genetic fingerprint is not found at the crime scene it means that you have no involvement in the crime, but if your genetic fingerprint is found at the crime scene, it doesn't mean you were responsible for the crime, but it does mean that you are a suspect.

DNA fingerprinting is far more conclusive because it is solid proof. It has evidence that a certain person was at a certain place at a particular time frame. Although most criminals do get asked to use the polygraph test, testing guilt I guess, measures only their heart rate. Which in a normal view many regular people would be nervous. There has been countless reports where murders can pass a polygraph test, but then be convicted of a crime due to proof of evidence from fingerprints. Humans are emotional beings, some can crack easily while some won't (through interrogation). So that's why it's key investigations use science to back up their crimes rather that try to measure someone's guilt.

I hope this answered your question!

How do you think the rock layers and fossils found in Red Rock Canyon can provide evidence for Earth's geologic history?

Bogdan [553]

Answer and Explanation:

Red Rock Canyon is an area of universal geologic interest, located a few miles west of Las Vegas within the Mojave Desert. Many experienced geologists visit the Red Rock; they are surprised by the vivid colors of rocks, natural beauty, and rock formations. A visual display takes million years to make the masterpiece known as the Red Rock Canyon National Conservation area. About 500 million years ago, Red Rock Canyon was found at the bottom of an ocean basin. Limestone accumulated in this ocean basin, which contains the fossils of sea life. The tracks of two-footed meat-eating dinosaurs have been found in the Aztec Sandstone. The tracks of small animals such as spiders, scorpions, early mammals, and proto-mammals were also found. The fossils and rock layers that are found in Red Rock Canyon provide evidence for Earth’s geologic history. Paleontologists are still searching these areas.
