The relationship between evolutionary time and the similarity of genes in two species?
The longer the evolutionary time between two species, the more dissimilar their genes are likely to be due to accumulating mutations. Conversely, species that share a more recent common ancestor are expected to have more similar genes because they have had less time to diverge through evolution.

What describes closely related species?
Closely related species are species that share a recent common ancestor and have a high degree of genetic similarity. They often have similar physical traits, behaviors, and ecological roles, indicating a close evolutionary relationship.
What does it mean when human DNA is similar to chimpanzee DNA?
The similarity between human and chimpanzee DNA (around 98%) indicates a shared evolutionary history between the two species. This common genetic heritage reflects a close evolutionary relationship and suggests a relatively recent divergence from a common ancestor.
What can help to determine evolutionary relationships between species?
Comparing DNA sequences, examining physical characteristics, studying fossil records, and analyzing embryological development can all help determine evolutionary relationships between species. Phylogenetic analysis, which looks at shared ancestry based on these characteristics, is a common method used in evolutionary biology.
What Scientist first hypothesized that gene sequences could provide new insights into the evolutionary relationship between organisms such as microbes?
Carl Woese was the scientist who first hypothesized that gene sequences could provide new insights into the evolutionary relationship between organisms, particularly microbes. He pioneered the use of molecular techniques to study the genetic relationships between different species of microorganisms.
What does it say when humans and chimpanzees have similar DNA?
Humans and chimpanzees having similar DNA suggests a close evolutionary relationship between the two species. It indicates a common ancestor from which both humans and chimpanzees diverged millions of years ago. The similarity in DNA points to shared genetic heritage and biological similarities.
What are 3 ways to determine the phylogenetic relationship among species?
DNA sequencing: By comparing the genetic sequences of different species, their evolutionary relationships can be inferred based on the similarities and differences in their DNA. Morphological characteristics: Examining the physical traits and structures of species can provide clues about their evolutionary history and how closely related they are. Fossil records: Studying the fossilized remains of species can reveal their evolutionary history and help determine their phylogenetic relationships with other species.
What is phylogeny?
I think you mean phylogeny. Phylogeny is the evolutionary history of a species or group of related species.
What describes closely related species?
Closely related species are species that share a recent common ancestor and have a high degree of genetic similarity. They often have similar physical traits, behaviors, and ecological roles, indicating a close evolutionary relationship.
Which observation could be best used to indicate an evolutionary relationship between two species?
They have similar base sequences.
Which type of fossil evidence helps determine the evolutionary relationship between two hominid species?
Comparing anatomical features in fossil bones, such as skull shape, tooth size, and limb structure, can help determine the evolutionary relationship between two hominid species. Fossils that show transitional features between the two species may also provide clues about their shared ancestry. Additionally, molecular analysis of ancient DNA from fossils can also contribute to understanding their evolutionary relationship.
What does the term missing link refer to?
The term "missing link" is often used in evolutionary biology to refer to a hypothetical ancestral species that fills the gap between different evolutionary stages. It is commonly used to describe a transitional fossil that would provide evidence for the evolutionary relationship between two different species.
What is the most conclusive evidence used in establishing the relationship of closely related species?
DNA sequencing is often the most conclusive evidence used to establish the relationship of closely related species. By comparing the genetic sequences of different species, scientists can determine the degree of similarity and divergence, providing insights into their evolutionary relationships. Additionally, the presence of shared anatomical features or similarities in embryonic development can also support the relationship between closely related species.
How comparisons between the proteins of two species can yield data about their evolutionary relationship?
Take the protein cytochrome C. There is not one amino acid difference in structure between we humans and our close relatives, the chimpanzees. There are 51 differences between humans and single celled yeast in amino acids. We can strongly and simply infer from this data the evolutionary relationship among the three species mentioned here.
What does it mean when human DNA is similar to chimpanzee DNA?
The similarity between human and chimpanzee DNA (around 98%) indicates a shared evolutionary history between the two species. This common genetic heritage reflects a close evolutionary relationship and suggests a relatively recent divergence from a common ancestor.
What does Co-Evolution mean?
Co-evolution refers to the reciprocal evolutionary influence between two or more interacting species, where changes in one species can drive adaptations in another species. This process often results in a close relationship and adaptation between the species involved.
Name one similarity between extinct and endangered species?
They are both species
What is the best measure of the evolutionary relationship between two species can be estimated from their?
