Would members of the same genus species or order have the most similar DNA?
Members of the same species would have the most similar DNA, as they belong to the same species and share a more recent common ancestor compared to members of the same genus or order.
What is an animal species?
In general, a species is a group of similar organisms that can interbreed and produce fertile offspring. More specifically, species can be defined as a group that has similar morphology, DNA, geographic distribution, and occupies the same ecological niche.The official definition for the word species is "a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus and denoted by a Latin binomial, e.g., Homo sapiens."
How does analysis of DNA help scientists establish an evolutionary classification scheme?
Analysis of DNA helps scientists establish an evolutionary classification scheme by comparing the genetic sequences of different organisms. The more similar the DNA sequences are between two species, the more closely related they are believed to be. By studying the similarities and differences in DNA, scientists can determine how different species are related to one another and create a classification scheme based on their evolutionary relationships.
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%.
What is the best evidence that organisms of two different species share a common ancestor?
The best evidence that organisms of two different species share a common ancestor is the presence of homologous structures. These structures have similar features due to shared ancestry, even if they serve different functions in different species. Additionally, similarities in DNA sequences and developmental patterns can indicate a common evolutionary history.
What was the name of the experiment that Meselson and Stahl worked on?
The experiment that supported the hypothesis that DNA replication was semiconservative was known as the Meselson-Stahl Experiment.
How similar is human DNA to that of chimpanzees?
Human DNA is about 98-99 similar to that of chimpanzees, indicating a close genetic relationship between the two species.
Would members of the same genus species or order have the most similar DNA?
Members of the same species would have the most similar DNA, as they belong to the same species and share a more recent common ancestor compared to members of the same genus or order.
How similar is human DNA to that of animals?
Human DNA is very similar to that of animals, as we share a common ancestry with many species. In fact, humans share about 98 of their DNA with chimpanzees, our closest living relatives. This similarity in DNA helps scientists understand the relationships between different species and how they have evolved over time.
Which term refers to a similar structures that related species have inherited from a common ancestor?
DNA sequences
What is the hypothesis for strawberry DNA project?
The hypothesis for a strawberry DNA project could be that strawberries contain DNA that can be extracted using household materials and that the DNA extraction process will yield visible strands of DNA.
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.
What species would the theory of evolution predict that human DNA is most similar to that of?
The two chimpanzee species Pan troglodyte and Pan paniscus.
How similar is the DNA of dogs and humans?
The DNA of dogs and humans is about 84 similar. This means that there are many genetic similarities between the two species, but also significant differences that account for their unique characteristics and traits.
Many phylogenetic trees are based on DNA sequence similarities What is the practical result of this similarity?
The practical result of using DNA sequence similarities in phylogenetic trees is the ability to infer evolutionary relationships between different species. By comparing DNA sequences, scientists can determine how closely related species are and reconstruct the evolutionary history of organisms. This helps in understanding the diversity and origins of life on Earth.
Is the theory true that the theory of evolution is supported by a wide range of biological evidence?
Yes. If evolution was not widely supported by evidence, then it would be regarded as a hypothesis rather than a theory.
Why do the body structures of some species support Darwin's theory?
a cell can make mistakes when it copies what in the dna
