Q: What is paraphyly?
A: Paraphyly is a term used in cladistics to describe a group that does not include all its descendants.
Q: Why is Sauropsida without birds considered paraphyletic?
A: Sauropsida without birds is considered paraphyletic because birds are descendants of archosaurs, specifically small theropod dinosaurs, and therefore should be included in the group.
Q: What is monophyly?
A: Monophyly is a term used in cladistics to describe a group that includes all its descendants.
Q: How can a paraphyletic group be corrected to monophyly?
A: A paraphyletic group can be corrected to monophyly by including the missing group(s).
Q: What is an example of a traditionally Linnaean paraphyletic classification?
A: Many traditionally Linnaean classifications are paraphyletic, but a common example is the classification of "fish", which does not include all its descendants.
Q: Is paraphyly a commonly used term in everyday language?
A: No, paraphyly is a technical term used primarily in cladistics and not commonly used in everyday language.
Q: Why are paraphyletic classifications still useful for everyday purposes?
A: While paraphyletic classifications may not accurately reflect evolutionary relationships, they can still be useful for everyday purposes, such as identifying common traits and similarities between organisms.
