The three groupings of the phylogenetic species concept are___________, ____________ and _____________.

monophyletic, polyphyletic, paraphyletic

What is the condition that make it a monophyletic grouping?

the condition that a group of organisms (taxon) contain the most recent common ancestors of all the group and its descendants.

the condition that a group of organisms (taxon) does not contain the most recent common ancestor of all the members of the group.

the condition that a group of organisms contains the most recent common ancestor of all the members of the group, but excludes some of the descendants of that ancestor.

Biological Species Concept.

1.

In the species concept what are the two types?

Explanation
The species concept encompasses two types: evolutionary and phylogenetic. The evolutionary species concept defines a species as a group of organisms that share a common ancestor and have a distinct evolutionary history. On the other hand, the phylogenetic species concept defines a species as a group of organisms that share a unique set of characteristics and are derived from a common ancestor. These two types of species concepts provide different perspectives on how to define and classify species based on their evolutionary relationships and characteristics.

A single lineage of ancestral-descendant populations that maintain its identity from other lineages and that has its own evolutionary tendencies and fate.
- A.
  
  Monophyletic Species
- B.
  
  Evolutionary Species
- C.
  
  Polyphyletic Species
- D.
  
  Phylogenetic Species
- E.
  
  Paraphyletic Species
Correct Answer
B. Evolutionary Species

Explanation
The term "evolutionary species" refers to a single lineage of ancestral-descendant populations that maintain their identity from other lineages. This means that these populations have distinct evolutionary tendencies and fate, separate from other lineages. Unlike polyphyletic species, which include multiple lineages with different ancestors, and paraphyletic species, which include some but not all descendants of a common ancestor, evolutionary species represent a cohesive and distinct group within the evolutionary tree. Therefore, the correct answer is "Evolutionary Species."

The three groupings of the phylogenetic species concept are___________, ____________ and _____________.

Correct Answer
monophyletic, polyphyletic, paraphyletic

Explanation
The three groupings of the phylogenetic species concept are monophyletic, polyphyletic, and paraphyletic. These groupings are based on the evolutionary relationships among organisms. Monophyletic groups include a common ancestor and all of its descendants, while polyphyletic groups include organisms that do not share a recent common ancestor. Paraphyletic groups include a common ancestor and some, but not all, of its descendants. These groupings help scientists classify and understand the evolutionary history of different species.

What is the condition that make it a monophyletic grouping?
- A.
  
  The condition that a group of organisms (taxon) contain the most recent common ancestors of all the group and its descendants.
- B.
  
  The condition that a group of organisms (taxon) does not contain the most recent common ancestor of all the members of the group.
- C.
  
  The condition that a group of organisms contains the most recent common ancestor of all the members of the group, but excludes some of the descendants of that ancestor.
Correct Answer
A. The condition that a group of organisms (taxon) contain the most recent common ancestors of all the group and its descendants.

Explanation
A monophyletic grouping is characterized by the condition that it contains the most recent common ancestor of all the group and its descendants. This means that all members of the group share a common ancestor and are descended from it. This condition ensures that the group represents a single evolutionary lineage, with no members excluded or having different ancestry.

An irreducible grouping of organisms distinct from other groupings within which there is a parental pattern of ancestry and descent.
- A.
  
  Monophyletic
- B.
  
  Polyphyletic
- C.
  
  Phylogenetic
- D.
  
  Evolutionary
- E.
  
  Paraphyletic
Correct Answer
C. Phylogenetic

Explanation
Phylogenetic refers to an irreducible grouping of organisms that is distinct from other groupings and follows a parental pattern of ancestry and descent. It involves studying the evolutionary relationships between different species and constructing a tree-like diagram called a phylogenetic tree. This tree represents the evolutionary history and common ancestry of the organisms.
