In a phylogeny or cladogram, distantly related organisms are placed further apart from each other on the branches or nodes of the tree. This indicates that they shared a common ancestor further back in evolutionary history as compared to closely related organisms which are placed closer together on the tree. The distance between branches or nodes reflects the amount of evolutionary divergence that has occurred between the organisms.

What does distantly related mean?
"Distantly related" typically refers to a relationship between two individuals or entities that share a common ancestor but are separated by many generations. In terms of genetics or genealogy, it indicates a lower degree of relatedness.
How is a cladogram used in classificatoin?
A cladogram is used in classification to show the evolutionary relationships between organisms based on shared characteristics. By analyzing the branching patterns of a cladogram, scientists can determine which species are more closely related and how they have evolved over time. This helps in organizing organisms into different groups and understanding the diverse range of life forms on Earth.
Where are organisms that are closely related located on the tree of life?
Organisms that are closely related are located closer to each other on the tree of life. This means they share a more recent common ancestor compared to organisms that are more distantly related. The branching points on the tree of life represent the evolutionary relationships between different organisms.
How are kingdoms and phylogeny different?
Kingdoms are a taxonomic rank used in biological classification to group organisms based on shared characteristics, such as the five-kingdom system which includes Animalia, Plantae, Fungi, Protista, and Monera. Phylogeny, on the other hand, refers to the evolutionary history and relationships among species, often depicted in a phylogenetic tree that illustrates how different organisms are related through common ancestors. While kingdoms categorize organisms for easier study, phylogeny emphasizes the evolutionary connections and lineage among them.
What is the best description about dissimilar organisms such as sheep and yeast?
When two organisms are notably dissimilar, such as a cow and a yeast, we can safely conclude that they are very distantly related. Organisms that are more similar to each other, such as a cow and a deer, are more closely related to each other.
What is a cladogram used to do?
A cladogram is used to show the evolutionary relationships between different species or groups of organisms. It helps to visualize how these species are related to each other based on shared characteristics and common ancestry. By analyzing a cladogram, researchers can infer patterns of evolution and determine the evolutionary history of a group of organisms.
What feature shared by all organisms allows scientists to compare distantly related organisms?
DNA
How are binomial nomenclature and phylogeny related?
Binomial nomenclature and phylogeny both have to do with organisms. The former refers to the modern scientist's system for naming organisms. The latter is about how an organism evolved over time.
Does phylogeny describe the evolutionary history of a group of related organisms?
internal for Plato users
True or False If two modern organisms are distantly related in an evolutionary sense then one should expect that they should share fewer homologous structures than two more closely related organisms?
True. The more distantly related two organisms are in evolutionary terms, the fewer homologous structures they are likely to share. Homologous structures are features that have a common evolutionary origin, so closely related organisms are expected to have more similarities in their structures compared to more distantly related organisms.
How are the words cladistics and cladogram related?
Cladistics is a method in biology for determining the evolutionary relationships between organisms based on shared characteristics. A cladogram is a visual representation of these relationships, showing how different organisms are grouped together based on their shared derived characteristics. Essentially, cladistics is the method used to create a cladogram.
What does distantly related mean?
"Distantly related" typically refers to a relationship between two individuals or entities that share a common ancestor but are separated by many generations. In terms of genetics or genealogy, it indicates a lower degree of relatedness.
How are phylogeny and kingdom related?
Kingdom and phylogeny are related because they both have to do with facts about the organism.
What is phylogeny?
I think you mean phylogeny. Phylogeny is the evolutionary history of a species or group of related species.
How is a cladogram used in classificatoin?
A cladogram is used in classification to show the evolutionary relationships between organisms based on shared characteristics. By analyzing the branching patterns of a cladogram, scientists can determine which species are more closely related and how they have evolved over time. This helps in organizing organisms into different groups and understanding the diverse range of life forms on Earth.
Why are molecular clocks not accurate when making comparisons between distantly related organisms?
Because rates of divergence are not static, but variable. The more distantly related the organisms, the longer the period of divergence. The longer the period of divergence, the more room there is for variability in the rate of divergence, the less accurate an estimate will be.
What is the name of evolution that produces similar but distantly related organisms?
Convergent evolution, or convergence theory.
