I will give a metal if you can tell me if I got any of these wrong 1. The grouping of organisms based on their common descent is called (1 point) traditional classification. binomial nomenclature. derived characters. ~~evolutionary classification.~~ 2. What kind of analysis focuses on the order in which derived characters appeared in organisms? (1 point) cladistic analysis traditional classification analysis ~~taxonomic analysis~~ anatomical analysis 3. Which of the following is the correct explanation of a derived character? (1 point) The presence of a backbbackbone. The presence of four limbs is a derived character of snakes because the ancestors of modern snakes had limbs, even though modern snakes do not. ~~The presence of hair is a derived character of mammals because all mammals have hair and no animals other than mammals have it.~~ Retractable claws are a derived character of carnivors because some of the animals that are carnivores have retractable claws. 4. Each node on a cladogram represents (1 point) the last point at which two groups shared a common ancestor. the point at which one or more species became extinct. the most recent point at which a trait was lost in a certain clade. ~~the point at which two clades joined and became monophyletic.~~ 5. DNA evidence (1 point) can solve evolutionary puzzles, such as how to classify organisms that look similar to one species but share peculiar behaviors with another. is not as reliable as physical characteristics or behaviors when used to classify organisms and determine evolutionary relationships. ~~has not resulted in any changes to cladograms that were created using observable traits or behaviors. ~~ can be used to classify organisms that are very different from each other, but not organisms that have close evolutionary relationships.

    Yes, some of these are wrong. Now, for Question 1, do you notice something in particular?

    "Common descent". We know a nomenclature is a term for lists of names.

    And classifying a group of organisms based on their "common descent" allows nomenclature. Common descent (nee Evolution). Good job.

    1.) evolutionary classification 2.) cladistic analysis

    3.) A "derived character" is a trait that arose in the most recent common ancestor of a particular lineage and was passed along to its descendants. Among a given group of organisms, the shared derived characters are generally the less common characters. The evolutionary interpretation is that these characters of organisms are more recently evolved. They are contrasted with primitive characters. Shared derived characters should have the same structure and function. Derived characters may be present in members of one group of the line, but not in the common ancestor. For example, in comparing fish and mammals, fish have scales and mammals have hair. So having hair is a derived character for mammals, as only the mammals have ancestors with hair.

    also It's where the common ancestor branches into new groups.

    DNA evidence is not as reliable as you think, however, it can solve evolutionary puzzles, such as how to classify organisms that look similar to one species but share peculiar behaviors with one another.
