The DNA evidence of polar bears can be derived from the DNA of a polar bear, which could be obtained from any cell produced by a polar bear. This polar bear DNA is unique to polar bears, and can be used identify a polar bear from other bears, and animals, and plants, and people.

The polar bear is a very close relative of the brown bear. The two species diverged around 80,000 years ago. They sometimes hybridize.

What animals are not related to Polar Bears?

The Brown Bear is the animal most closely related to the Polar Bear. Considering DNA and fossil evidence the Polar Bear diverged from the Brown Bear thousands of years ago. The Grizzly is more distantly related, but they do have some connection to the Polar bear. That leaves most all other animals not related to the Polar Bear.

What is the relationship between the polar bear and the brown bear?

According to both fossil and DNA evidence, the polar bear split from the grouping of the brown bear, Ursus arctos, roughly 200,000 years ago. This is thought to have happened due to their isolation during a period of glaciation in the Pleistocene period.


What is the polar bear evolution?

According to fossil and DNA evidence the polar bear evolved from the brown bear. Bears, in the taxonomic family of Ursidae, split off from other Carnivorans about 38 million years ago. Then the Ursinae subfamily originated around 4.2 million years ago. The polar bear split from the grouping of the brown bear, Ursus arctos, roughly 200,000 years ago. This is thought to have happened due to their isolation during a period of glaciation in the Pleistocene period.


How is DNA evidence used in evolution?

All species have the same genetic code.


What is genetic evidence?

Genetic evidence refers to information gained from studying an organism's DNA, such as its genes, mutations, and hereditary characteristics. This evidence can help scientists understand genetic traits, evolutionary relationships, and potential disease risks in populations.


What is molecular evidence or a DNA sequence?

Molecular evidence refers to data obtained from the study of molecules such as DNA, RNA, or proteins. A DNA sequence is the order of nucleotides (A, T, C, G) that make up an organism's genetic code. By analyzing DNA sequences, researchers can gain insights into evolutionary relationships, genetic mutations, and other biological processes.


Describe How Averys experiment supplied evidence that DNA and not protein is th genetic material?

His experiment supplied evidence that DNA is not the genetic material by showing that the activity of the material responsible for transformation was not affected by protein-destroying enzymes, but was destroyed when a DNA-destroying enzyme was present. Cristian Mendoza 11/1/12

What summarizes the findings of Hershey and Chase?

Alfred Hershey and Margaret Chase confirmed that DNA is a genetic material.


What evidence can be used to show that organisms share a common ancestor?

The DNA genetic code provides the best evidence of the common ancestry of life. Science has shown that there are many similarities between DNA sequences.


What pieces of evidence would be considered the best for establishing biological relatedness?

The best pieces of evidence for establishing biological relatedness are DNA analysis through techniques like DNA sequencing or DNA fingerprinting, which can compare genetic similarities between individuals. Other evidence can include blood type analysis or inherited genetic traits passed down through generations. Ultimately, a combination of different biological markers and genetic tests can provide a comprehensive picture of relatedness.


How is evidence from DNA useful in understanding the evolution of species?

DNA molecules contain the assembly instructions for every living creature. Scientists compare DNA from ancient and present creatures to identify genetic similarities among species. The genetic similarities among species is the main evidence of evolution theory.
