What 2 animals have genes in common?
Humans and chimpanzees share approximately 98.7% of their DNA, making them the two animals with genes in common. This high level of genetic similarity points to a shared evolutionary history between the two species.
Are more alike DNA sequences more closely related than species are?
Yes, more alike DNA sequences typically indicate a closer evolutionary relationship between species. When DNA sequences are similar, it suggests that the species share a more recent common ancestor. Conversely, greater differences in DNA sequences imply a longer evolutionary divergence. Thus, genetic similarity can be a strong indicator of relatedness among species.
DNA for certain proteins such as cytochrome is more similar in closely related species than it is in species that are less closely related why?
This is because closely related species share a more recent common ancestor, leading to a more recent divergence in their DNA sequences. As species diverge over time, accumulation of genetic mutations cause differences in their DNA. Therefore, closely related species have had less time for genetic mutations to accumulate, resulting in more similar DNA sequences for certain proteins like cytochrome.
Why is your DNA 75 percent similar to that of a fruit fly?
The reason for the high similarity between human and fruit fly DNA is due to shared evolutionary history. Both species have common ancestors from millions of years ago, which has resulted in certain genetic similarities that are preserved across evolution. Despite the overall genetic similarity, differences in specific genes and genomic structures account for the distinct characteristics of each species.
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.
Which characteristics do scientists to use to group species?
Scientists use Ancestors and DNA to group DNA.
What characteristics do scientists use to group species?
Scientists use ancestors and DNA to group species.
What evidence is there that most organisms came from common ancestors?
Common DNA
How does DNA sequences can provide evidence of evolution?
DNA sequences can provide evidence of evolution by showing similarities and differences in the genetic code of different species. By comparing DNA sequences between species, scientists can identify common ancestors and evolutionary relationships. Changes in DNA over time, such as mutations and genetic variations, can also provide clues about how species have evolved and adapted to their environments.
How do paleontologists study ancient species?
Palaentologists study ancient species by the fossil remains, footprints, by the traces of animals and DNA with comparision with their ancestors
How do you prove this statement The ancestors of Primates is a tree-dwelling insectivore?
It can be proved by DNA testings on bones. After that you can look at the teeth to find out what they ate.
What evidence supports the theory that animals with common ancestors have evolved over time to adapt to different environments?
The theory of evolution is supported by evidence such as the similarities in DNA and physical traits among different species that share common ancestors. This suggests that animals have evolved over time to adapt to different environments in order to survive and thrive.
What 2 animals have genes in common?
Humans and chimpanzees share approximately 98.7% of their DNA, making them the two animals with genes in common. This high level of genetic similarity points to a shared evolutionary history between the two species.
If two species have similar DNA what hypothesis is supported?
When the DNA is similar between two species it means there is a biological connection to each other.
What is the one way in which scientist get information about the evolutionary history of species?
One very important way that information is compared in the evolutionary history of a species is to use DNA. By checking how much is the same between species, we can see if those species are closely related or not. Our own DNA and that of the great apes are only different in about 1-2%.
How does DNA help find common ancestors?
well DNA is like hair pieces and etc right. well if they were to run that through a machine i believe they can see who's got the closest genes and DNA to you.
How does DNA show how animals are related?
Through the study of DNA gene sequences they can determine which sections of the DNA have been inherited from a common ancestral species.
