Answer:
You're going to want to look at the the phylogenetic tree. Here's a video explanation: http://highered.mcgraw-hill.com/sites/9834092339/student_view0/chapter23/animation_-_phylogenetic_trees.html Here's an interactive chart displaying the Latin names: http://itol.embl.de/itol.cgi Here's a poster with pictures you can buy: http://vi.sualize.us/view/5b51bae4da6c908c2a92b6ab64b22afd/ Here's a simplified view that highlights the mammals: http://www.philvaz.com/apologetics/TREE.gif And here's a thumbnail image just to show how fully developed this concept is, in its detail.

there must "have been in the past" intermediate animals -- they wouldn't necessarily have descendants living today

"mammal", "reptile", "bird", "cat" and all those other words are just words - invented by us to divide up the things we see according to similarities we see. Animals did not set out to become "mammals". For a good read, start here: http://en.wikipedia.org/wiki/Evolution_of_mammals

The platipus is a mammal laying eggs!
Not so Loony gone Ape
Nipples and milk glands are modified sweat glands, so obviously, babies licked their mommas' sweat, and the mommas with more nutritious sweat had babies with increased survival chances.

Here is a cool site that explains it better than I could: http://www.mnh.si.edu/mammals/pages/how/index.htm BTW - it's not the missing link you're looking for but it's probably decedent from it: The duck-billed platypus and egg laying mammal. http://www.sciencedaily.com/releases/2008/05/080507131453.htm
