Evolution of Cetaceans
This definition states how cetaceans (whales and dolphins) evolved for the last fifty million years.. Around 50 million years ago, there was a completely terrestrial mammal called Pakicetus. Pakicetus would occasionally go to the river banks to catch and eat fish. This would require swimming skills. This eventually drove Pakicetus to evolve. The legs became suited for water, and it learned how to hold its breath longer. Pakicetus evolved into Ambulocetus, which in turn evolved in Rodhocetus. Rodhocetus had limbs for diving, along with a blowhole, but had no purpose for land travel. Rodhocetus soon lost its hind legs and became Dorudon around 40 ma. Dorudon had dorsal fins and would give raise to many types of dolphins and whales in its future. The proof for the evolution of cetaceans is that they have a pelvic bone that remains where their legs had once been. That is it...

Perfect coffee cup for a hockey fan. Great conversation starter.
Perfect gift! My husband loved it. So funny and clever!
Great mug… got one for my girlfriend… instant sex
As always, these are well made mugs that stand up to most anything. And they make perfect gifts (in this case for dirty-minded members of a wedding party). I’m extremely pleased.
Is a great mug that I purchased as a gag gift for a coworker. You know the one who also as interesting words/phrases that only urban dictionary can explain. Great as a coffee mug and better as conversation piece!

The mug exceeded my expectations. Really excellent quality and build
Jim, you’re a fucking idiot interfering with accurate ratings and legitimate feedback. Get a hobby.
Great gift!
A little spendy, but worth it.
My wife kept talking about "ways out" being a Denver version of "psych" and she was right, so I got her this once I found it on UD. She loved it!
It's a great mug, will reccomend to family members my grandma gave me this mug for christmas and it was by far the best gift i got.
It arrived three weeks after ordering but given the holiday rush and inability of shipping to keep on schedule arrived late but was perfect little gift from me to my wife for her morning coffee with her "nickname" on the mug.
I liked the photo on your website and so I ordered the mug. You sent it right away, and it looks great!
Arrived carefully packaged
