Is bacteria a clade?

Bacteria is a clade if you (or anyone else) say it is. However, neither biodiversity nor anything else can be non-contradictory partitioned into clades, so the question does not have any non-contradictory (unambiguous, or objective) answer. Clades are and will always be purely subjective.


Which form of classification groups animals based on their phylogenetic similarities?

Phylogenetic classification groups animals based on their evolutionary relationships and shared ancestry. It organizes species into groups called clades, which include an ancestor and all its descendants. This form of classification aims to reflect the evolutionary history of organisms.


What clades has been proposed by plant biologists as the clade that defines the plant kingdom?

Plant biologists have proposed the clade Viridiplantae as the group that defines the plant kingdom. Viridiplantae includes all land plants as well as green algae. It is characterized by the presence of chlorophylls a and b and cellulose cell walls.


In cladistic analysis a characteristic that arises as a lineage of organisms evolves over time is called a?

In cladistic analysis, a characteristic that arises as a lineage of organisms evolves over time is called a derived trait or synapomorphy. These traits help define clades within a phylogenetic tree by marking unique evolutionary advancements shared by a common ancestor and its descendants.


How does variation within a clade affect clade's chance of surviving environmental change?

Variation within a clade increases the likelihood that at least some individuals will have traits that are advantageous in the face of environmental change. This genetic diversity allows for some members of the clade to survive and reproduce, passing on their beneficial traits. As a result, clades with greater variation are more likely to adapt and survive in changing environments.

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.


Why are some clades very diverse and some unusually sparse?

Clade diversity often results from factors like ecological opportunities, adaptive radiation, and evolutionary history, allowing certain lineages to exploit a wide range of niches. Conversely, sparse clades may arise due to ecological constraints, limited geographic distribution, or historical events such as mass extinctions that reduce available habitats. Additionally, specific traits that enable adaptability or survival can contribute to the success and expansion of some clades over others. Overall, the interplay of environmental factors, evolutionary dynamics, and chance events shapes the diversity observed in different clades.
