The prevailing theory is called cladistics. This relies on unique homologies, or structures which members of the clade possess to the exclusion of all other clades. For example, all mammals give milk (the females, anyway) and no other animal gives milk, so mammals are a distinct clade, in this case, a "class." Smaller distinctions determine that certain creatures belong in smaller clades, called "orders," "families," "genera" and "species."

∙ 10y agoFour types of evidence used by systematic toxonomists are:
1 Embryological development- cell fate in tissue differentiation - hox regulation
2 physical homology between analogous anatomic features
3 genetic homology between shared expressed genes or protein homology, often using mtDNA but also chromosome synteny (gene order on chromosome) in comparing whole genomes
4 Ecological niche, behavior, biogeographic distribution- biochemical, physiological, or behavioral characters may be at least as good as anatomical characters for discriminating between closely related species.

What is used by modern taxonomists to determine evolutionary or ancestral relationships among taxa?
Phylogenetics
Tool used to identify organisms already classified by taxonomists?
taxonomic key
Possible rationales that taxonomists might have used when deciding to group prokaryotes into two distinct domains instead of one group?
Taxonomists found many differences that have led them to classify bacteria into different domains. And some differences include; bacterial cell walls contain peptidoglycan but archaea do not; different lipids in their plasma membrane; and different ribosomal proteins and RNA.
What is used as evidence for the idea of a domain Eukarya evolved from unicellular organisms?
Mitochondria and chloroplasts have their own dna
What is the language used for scientific names?
Latin, or modern languages conforming with the rules of Latin.

Can a message saved to your voice mail be used as evidence in small claims court in Maryland?
Yes, it doesnt matterwhat kind of evidence there is, as long as it supports your case.
Name a tool used by systematic taxonomists?
Key.
What is the modern theory of plate tectonics and what evidence is there to support it?
the modern theory is that all the continents used to be connected (Pangaea). The evidence is that the coastal boundaries fit together like a puzzle piece. another example is that the same species of animals are found on the coasts of the continents that once were touching
What kind of clothing did modern humans wear?
modern humans used lether from the animals and stitched it together to make pants,shirts and shoes.
What kind of kites were used for weather?
There are different kinds, old and modern. Read the attached article.
What kind of evidence is used to determine the relationships between animals?
Everything from where they live to body structure. Sometimes even size.
Can text messages be used as evidence?
Anything can be used as evidence if it is obtained in a legal manner. Therefrore text message can be used as evidence if the evidence was legally obtained.
