Class and Order question.

Postby REN » Tue Mar 27, 2007 8:19 pm

Scientist classify Storks and Herons in the same order. Do Storks and
Herons necessarily belong in the same class? Why or why not.

I tried to read it in my textbook but it has been a bit confusing.

Ren, the carnivora class only exists under mammalia, since birds aren't mammals, they can't be carnivora. Each lower grouping branches from an upper grouping and the branches only intersect going higher up, the lower branches don't really intersect with other lower branches that come from different classes, orders etc...
this might be a slightly more helpful picture

Anyway, I think the concept is if they're in the same lower taxon(lower level grouping), they're necessarily from the same higher level grouping. So if cats and dogs are both carnivora, they necessarily have to also be under mammalia since that's the only class that has carnivora. Now, the question is probably testing you whether the reverse is true. Hint(there's more that one lower taxon for every higher one).

Okay, you said that "..if they're in the same lower taxon(lower level grouping), they're necessarily from the same higher level grouping." So, the question is asking me if Herons and Storks are in the same order, are they in the same class. Considering what you said and what I read from the internet, the answer would be yes right?

Your on the right track, let me try and explain it in a different way.
This is your hierarchy:
Kingdom
Phylum
Class
Order
Family
Genus
Species

So if 2 taxa are in the same order then they must also be in all of the same groups higher in the hierarchy, but it would not necessarily be in the same lower groups in the hierarchy.

For example if there is Room 'A' (taken as 'class') the teacher has divided the students present in the room in various groups called "orders"....now two students A n B are in the order 1 so what would be their class? ofcourse Room "A"...
