What is the difference between a clade and a monophyletic group in evolutionary biology?

In evolutionary biology, a clade is a group of organisms that includes an ancestor and all of its descendants. A monophyletic group is a type of clade that includes only the most recent common ancestor and all of its descendants. So, all monophyletic groups are clades, but not all clades are necessarily monophyletic groups.


What is a group called that includes an ancestor plus all its descendants?

monophyletic


What is the highest subgroup for classifying organisms?

Kingdom is the highest subgroup for classifying organisms.


Are prokaryotes monophyletic?

Yes, prokaryotes are monophyletic, meaning they share a common evolutionary ancestor. This group includes bacteria and archaea, both of which are characterized by lacking a true nucleus and other membrane-bound organelles.


Which type of character is found within an entire line of descent of a group of organisms?

A monophyletic group includes a common ancestor and all of its descendants, representing a single evolutionary lineage. It is characterized by shared derived traits, called synapomorphies, and is considered a natural (or clade) group in evolutionary classification.


How do you identify clades?

Clades are identified based on shared derived characteristics, also known as synapomorphies, that are unique to a group of organisms and their common ancestor. These characteristics are used to group organisms into phylogenetic trees that show evolutionary relationships. Using molecular data such as DNA sequences, researchers can analyze these shared characteristics to determine clades.


A species is the lowest subgroup for classifying organisms?

false


What is synapomorphy?

It's a trait common in a single monophyletic group,but not generally found outside of that group.


What characteristics define a monophyletic group or clade and how do they contribute to the evolutionary relationships within a specific taxonomic group?

A monophyletic group, or clade, includes an ancestor and all of its descendants. This grouping is based on shared evolutionary traits, called synapomorphies, which help determine the evolutionary relationships within a specific taxonomic group. By identifying these shared characteristics, scientists can better understand the evolutionary history and relatedness of different species within the group.


What is the discipline of biology that focuses on classifying organisms and determining their evolutionary relationships?

The discipline of biology that focuses on classifying organisms and determining their evolutionary relationships is called taxonomy. Taxonomists use morphological, genetic, and ecological characteristics to group organisms into categories such as species, genus, family, and so on, based on evolutionary relatedness.


Are fish monophyletic?

No, fish are not monophyletic. The term "fish" is a paraphyletic group because it includes some but not all descendants of a common ancestor. It does not include tetrapods (four-limbed vertebrates such as amphibians, reptiles, birds, and mammals) which share a more recent common ancestor with some fish species.


Which of these classification groups includes the greatest variety of organisms?

Kingdom is the classification group that includes the greatest or widest variety of organisms.
