clade thread
For example:
1. We want to treat these animals this way because their common ancestor was this.
2. Because the common ancestor of these life forms was this, so they are unique in providing this material for this purpose.
etc.
I think I understand. Cladistics would not necessarily be needed for this as for most cases Linnaean and Cladistics probably would produce adequate results. Keep in mind that dogs and humans have the same organs as far as I know. In other words, show a human organ that a dog does not have or the other way around. There are variations on the organs but the basics are the same (example: color vision in dogs and humans).
But to respond your questions as best I can, (This is rapidly getting out of my range.)
"1. We want to treat these animals this way because their common ancestor was this."
This is done a lot with animal studies in medicine. For the most part, the more closely related the species the more likely the reactions to medications will be similar. Another example, a broad one, would be treating all mammal reproductive systems as similar due to common ancestry.
"2. Because the common ancestor of these life forms was this, so they are unique in providing this material for this purpose."
I am not sure just what you mean by this but I will give one possible example. Xenotransplantation (learned a new word-cool) , the transplantation of organs from animals to humans is an active field of research. The cladistic relations appear to be very important to this as genetic similarities would be very relevant here.
I think the big thing though is that like the periodic table was developed primarily for use of scientists but is used in a number of ways so is biological classification. Linnaean taxonomy was good but cladistics appears to give us a more accurate way of determining genetic relationships where Linnaean taxonomy could not.
If I am off on any of this, could someone with better knowledge correct me?
Both the table of elements and cladistics as well as Linnaean taxonomy were developed for primarily scientific purposes and practical aspects are a bonus.
What I like about conversations like this is that it gets me to do research I might not have done otherwise.
