So, if I understood well, natural puzzle has to do with nature, right?

That would a question for Prof. Arno, I suppose.

I would think that natural is whatever we did not build ourselves. 

A question such as, did we come from Apes or not?, would not be a natural puzzle because we invented this theory, right? 

Would puzzle be a question then? I think that is more like what Prof. Arno is saying. 

Did you mean paradox, by chance? Could you have meant that? I have a fair bit of work on paradoxes. You can see a bit on my profile here.

What is the circular 'artwork' on the sea-bed? 'Art' in our eyes, but see the fish's perspective...

Dear All

Thanks for your contribution,

Dear Marcia What i mean from the Natural Puzzle was any phenomenon, event, etc which is designed by Nature and against our observation we don't find the solution yet.

Anyhow What Prof. Arno told is a good example proposals as well.

Dear Ivo Carneiro you are very right "I wonder if "natural" puzzles are only natural up to their human assemblage and understanding."

For some how we can add mysteries in Nature, as well to find the puzzles example.

Thanks

The common cuckoo presents an interesting case in which the species as a whole parasitizes a wide variety of hosts, including the reed warbler and dunnock, but individual females specialize in a single species. Genes regulating egg coloration appear to be passed down exclusively along the maternal line, allowing females to lay mimetic eggs in the nest of the species they specialize in. Females generally parasitize nests of the species which raised them. Male common cuckoos fertilize females of all lines, maintaining sufficient gene flow among the different maternal lines to prevent speciation

Thanks Dear Pierlorenzo Brignoli

Yes, co-existence is a game of puzzle as constituents are not fixed in many parameters and the approach toward "medium" source is relative to tendency of adaptability.

Dimensional Shifts, Universal Center of Consciousness, Origin of ability of "Movement"  etc etc , there are many things which are mysterious and Natural puzzle

Dear all,

firstly, we need to know, what’s a natural puzzle?

Natural pazzle is a perplexing natural process, occurrence, behavior or phenomenon that makes us to ask. What? When? Where? How? Why?

Natural puzzles inspire in dominance the curiosity, the speculation, the scientific inquiry, the wonder, the folklore and the even superstition. Some puzzles call for intense or immediate study and resolution. Examples: What’s eating my chestnut plants? What’s causing honey bee colony collapse disorder?

Others puzzzles needn’t be resolved, but simply arouse our curiosity and challenge our powers of observation and investigation

Let's go to monkey puzzle tree problem

I planted a 6" monkey puzzle tree 7 years ago. It grew into a healthy 7' tree, and I transplanted it 2 months ago to a new location (about 15' away) at my home in Chilliwack. I prepared the new location with a 3' diameter and 2' deep hole and then proceeded to carefully remove the tree from it's original location. However the tap root extended about 2.5 feet deep so I attempted to extend the depth of the new location another 6". However, at just over 2 feet deep, I ran into a hard-pan type soil which obviously isn't going to give great drainage for a monkey puzzle tree. I proceeded with the transplantation anyway, planting at the same depth and direction as before, using root booster and good quality soil around the tree. I gave it a fair bit of moisture for the first 4 weeks, and less over the last 4 weeks to hopefully avoid root rot. The tree was looking great for the first 7 weeks, but now on the lower half of the tree, the leaves are starting to turn brown, and 3 or 4 of the branch tips are becoming droopy. Is there anything I can do to save my tree?

Dear Raja, these site maybe useful for you.

Dear Raja,dear All,

The question(puzzle) is "When will Humanity stop their irresponsible, careless, greedy policy towards Nature?"I  used these materials thanks to our dear Ljubomir.

Dear Irina Pechonkina 

Creatures never be out from the Set of logic given by Creator/Designer........creatures usually just produce response as reactions..... So all the responsibility is not on Human or any other intelligent creature.....Yes i agree that in case of Natural Ecosystems at Earth, human are ethically responsible for its sustainability with care and by all possible means.
