A clade is a grouping of organisms based on relatedness while a grade is a grouping of organisms based on: behavioral similarity, levels of adaptation, fossil dating, or all of the above.

Step 1
A clade is a grouping of organisms based on their evolutionary relatedness, meaning all members of the clade share a common ancestor and are therefore considered to be part of the same evolutionary lineage. Show more…

Which of the following is true: Group of answer choices Clades are groupings that reflect levels of adaptation or overall similarity and not necessarily actual evolutionary relationships. A grade is a grouping of organisms that reflects a branch of the evolutionary tree. Prosimii and Anthropoidea are an alternative grade-based classification. Genetic evidence suggests that Tarsiers are more closely related to Lemurs and Lorises than they are to haplorhines. None of the above.

A clade is $a$ a type of phylogenetic tree. b. a group of evolutionarily related species that share a common ancestor. $c$ a tool for constructing phylogenetic trees. $d$ an extinct species. $e .$ an ancestrai species.
A clade is defined when: all individuals share many ancestors and those ancestors share most descendants. All individuals in the clade derive from a single clade ancestor and most of the descendants of that ancestor are in the clade. Most individuals in the clade derive from a single ancestor and all the descendants of that ancestor are in the clade.
