The mammal trait of having fur is an example of a derived character because?
A synapomorphic (derived) character is defined as a trait that multiple taxa and their last common ancestor possess, but that the ancestor of this last common ancestor did not possess. The multiple taxa in this case could be the 29 orders of mammals, all of which have fur. All mammals descend from cynodonts. It is probable that cynodonts were covered in fur. Cynodonts evolved (with various steps in between) from early amniotes, which did not have fur. We do not know when exactly fur appeared in the evolution of mammals.
Why is it easier to group mammal in taxa but not human?
because humans are more closely related to animals and not all mammals
Which of the following are problematic when the goal is to construct phylogenies that accurately reflect evolutionary history A monophyletic taxa B polyphyletic taxa C paraphyletic taxa?
Polyphyletic and paraphyletic taxa are problematic when the goal is to construct phylogenies that accurately reflect evolutionary history. These taxa do not accurately represent the evolutionary relationships between species and can lead to incorrect interpretations. Monophyletic taxa, on the other hand, are ideal for constructing phylogenies as they include all descendants of a common ancestor.
A phylogenetic tree that is rooted is one?
At whose base is located at the common ancestor of all taxa depicted on the tree.
What is the Simpson Coefficient?
C/N x 100 (where C is the # of taxa in common between two areas and N is the total # of taxa.

What fact implies that Nearly all mammals have seven cervical neck vertebrae?
all mammals descended from a common ancestor.
What group of mammals has the most members?
There are three main infraclass taxa into which the mammals are divided. These divisions are based on how the young are born. Of the monotremes, the marsupials and the placentals, the placental mammals far outnumber the others.If you meant orders, then Rodentia is the largest, followed by Chiroptera (bats).
What do birds snails mammals and reptiles have in common?

What is the Jaccard Coefficient?
C/(A+B-C) (where C is the number of taxa in common between two samples and A and B are the numbers of unique taxa found in each of the two samples).
