When I was a kid, I would go to a local swamp about a mile away and scoop out a bucket of sluge to take home. If I let it sit for a while, some very large (about an inch long) planarians would come to the surface!

You will have better success in getting comments on your ideas if take parts of your overall idea and ask questions about specific little parts and their relations with physics understanding.

I have a dog that likes to have things thrown for her to catch, but she will only drop it where she is instead of bringing it back for another throw. You have to fetch the item to throw it again (often on the other side of the room). Its not happening a lot because she is not training us well...

Happy Darwin Day! Building on Darwin's example, persist in your scientific inquiries and curiosity.

OK since the scenarios are getting a bit non-standard, instead of translating froom randomor made up languages to English, what about translating between jargon and non-jargon? Many science words are international in that they are so similar in different languages (so said my Russian teacher)...

Good catch. I would guess the colors are for the humans who buy them. The dogs should only perceive differences in intensity of light (perhaps due to saturation differences). It raises the question: are the different colors always paired with the same colors.

Its too bad you could not see the actual video. The pet owner aspect is dealt with pretty well in the video. It is a complex examination of the subject that a brief post will not do justice to. The question of the dogs' understanding is examined in several ways, both statistically (based on...

If deception is a sign of intelligence, then biology which is full of deception should be very intelligent (due to selection presumably). Since selection works by selection things that work best in some way to produce the next generation, its not a deep intelligence. Might be considered a...

Here is a nicely done PBS documentary on the ability of dogs to communicate. There are several different approaches to possible dog communication, but its mostly focused on dogs pushing talk buttons. These are mostly on home button boards that make speech sounds when the dog pushes it (like...

This argument can be much stronger if one were to consider free-living single cells, rather than those that are part of a larger organism. The decisions are more obviously made by the single cells.

Shrink it down and make it a response emoji, like these:

Here is a convincing explanation of what happened with Amelia Earhart. The guy is someone who investigates accidents for insurance companies. Lots of circumstantial evidence.
