How do scientists use geographical distribution to determine the evolutionary relationship?
Organisms that are close geographically are usually more closely related than those that evolved in widely separated areas of the world.
Are modern birds more closely related to archaeopteryx or the first reptiles?
A evolutionary form of a bird. It had wings and feathers but still probably acted like a dinosaur but im not sure.
What generalization can you make about identifying how closely organisms are related?
if 2 or more organisms have more than one of the following the same, they are closley related: kingdom, phylum, class,order,family,genus,and species
How does a branching tree diagram divide organisms into groups?
A branching tree diagram, also known as a phylogenetic tree or cladogram, is a visual representation that groups organisms together based on their shared derived characteristics. This diagram illustrates the evolutionary relationships between different species or groups of organisms. The process of creating a branching tree diagram starts with identifying the shared derived characteristics among the organisms being studied. These characteristics are traits that are unique to a particular group of organisms and have been inherited from a common ancestor. Examples of derived characteristics could include the presence of feathers in birds or the possession of a backbone in vertebrates. Once the derived characteristics are identified, the diagram is constructed by placing the organisms into branches or clades based on their shared derived traits. The more closely related organisms will be grouped together on branches that are closer to each other, indicating a more recent common ancestor. Conversely, organisms that are less closely related will be placed on branches that are more distant from each other, showing a more distant common ancestry. The branching pattern of the tree diagram represents the evolutionary relationships between the organisms. The points at which branches meet, called nodes, represent common ancestors from which the different groups have diverged. The length of the branches can indicate the amount of evolutionary change or time that has passed since the divergence from a common ancestor. Branching tree diagrams are valuable tools in understanding the evolutionary history and relationships between organisms. They provide a visual representation of the shared derived characteristics that define different groups and allow scientists to study patterns of evolution and common ancestry. These diagrams are used in various fields such as biology, paleontology, and taxonomy to classify and identify the relationships between different organisms.
Why are monerans placed in a unique kingdom?
The kingdoms Eubacteria and Archaebacteria (aka domains Bacteria and Archaea) contain prokaryotic organisms, or organisms without a true nucleus. The kingdom Monera was used to include all the organisms of both kingdoms but was split once taxonomists realized that archaebacteria are more closely related to eukaryotes than eubacteria.
What is an evolutionary?
If two organisms share an evolutionary relationship, that means that they have a common ancestor on the evolutionary tree. The more recently the shared common ancestor lived, the more closely related the two present organisms are, evolutionarily.
HOW ARE THE AREA OF STUDY -EVOLUTION AND CLASSIFICATION-INTERLINK?
Evolutionary relationships are traced in the classification of organisms. For classification of organisms, we look for similarities among organisms which allows us to group them. The more characteristics two species will have in common, the more closely they are related. It indicates that more closely two species are related, the more recently they would have had a common ancestor. Thus, classification of species is in fact a reflection of their evolutionary relationship.

What does it mean for species to have an evolutionary relationship?
If two organisms share an evolutionary relationship, that means that they have a common ancestor on the evolutionary tree. The more recently the shared common ancestor lived, the more closely related the two present organisms are, evolutionarily.
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, they should share fewer homologous structures than two more closely related organisms.
How do scientists use geographical distribution to determine the evolutionary relationship?
Organisms that are close geographically are usually more closely related than those that evolved in widely separated areas of the world.
How do scientists get information on the evolutionary history of a species?
they are classified more closely together
In which group of organisms are the members more closely associated?
The group of organisms where members are more closely associated is species. Genus is the next one group where members are closely related.
How does DNA sequence analysis contribute to evolutionary theory?
It's common sense that organisms with similar DNA are more related evolutionary-wise. Analyzing DNA can help us determine which organisms evolved from which organisms.
How can you determine how closely related organisms are from their taxonomy?
You can tell how closely related organisms are by determining the lowest classification that they share. For example, organisms that share the same genus will be more closely related than organisms that share the same family.
Why are DNA sequences more similar in more closely related organisms?
In fact the organisms are closely related because the DNA sequences are more similar. DNA sequences are more different as the organism differs.
Which are more closely related to complex organisms bacteria or archaea explain?
On basis of cladistic analysis higher organisms are more closly related to Archaea .
