Wondering if here are any theories as to why there are no saber toothed cats (e.g. Smilodon, etc) alive? Or conversely, why no current cats have such long canines, but previous felines evolved them. Was there some environmental/evolutionary benefit that existed then but not anymore?
Hi all,
Recently moved and the house came with a very lovely Japanese Maple. The only problem is the tree is located right smack in the middle of the front of the house. Presently, it is large enough to block the entire porch.
Everyone around us has advised that these trees can be expensive. I also feel conflicted killing it. Is this a tree that is worth replanting or rehoming? How would you proceed?
Thank you!
Are capybaras in the process of evolving down the path that leads to fully aquatic mammals (whales, seals, etc)?
