    Its only sort-of true.

    The tomato imported to Europe was more like the cherry/mini pear tomato and yellow in color. Cultivars like we know today we’re mostly developed in the 18th and 19th centuries in different European regions.

    Why do I say it’s mostly true.

    Modern breeders have extensively introgressed traits from wild types from Central and South America. Almost all modern cultivars contain DNA from multiple different locations. So it’s not really fair to say it’s all from Europe.


  • Its a trade show classic. Have a nice looking bowl full of candy to draw people in. More thought needs to be placed into the contents of the candy bowl than the layout of the booth.

    What’s in that bowl determines the amount of traffic that stops. Matching the candy to the demographic of the audience is a critical research before the trade show.




  • That was the theory and how it works in a petri dish, however that’s not how it works in the body.

    Antibiotic treatment doesn’t have to kill all of the bacteria. It needs to kill enough so the immune system can catch up and finish the job.

    There been evidence for more than 50 years that overly long antibiotic treatments cause resistance to build up faster. That’s why they have limits on the first place.

    So there’s a balance between too few days, and to many.


  • Hydroponic greenhouses in the late 1970’s for one bankruptcy. Off a deep well on a high mountain valley with water that came out of the ground at 6-8C… Oh and brutally cold winters down to -30C The heating cost alone for the water was prohibitive. They blamed the Mexicans for “tanking the market” for that bankruptcy.

    On the other side, they always chased last year’s market. Sugarbeets were high so they doubled their acres - bank forced sale of 300 on that one. Beef was high so they bought steers ar extremely high prices and then sold them at a loss… bank forced the sale of another 400 acres plus they lost their grazing contract. The last one was lamas. Yep they bought 100 of them… Somehow it was the blacks fault for that one… never did quite figure out how. I currently guess the bank got a new loan manager who happened to have a darker skin color.


  • Nope, that’s not what it means at all

    Genetically linked behaviors follow distribution curves. There is always variation in every population for any behavior. When a behavior is highly selected for, alternative behaviors become more rare…but they still happen.

    A good example of this is homosexuality, evolutionarily speaking this behavior is highly selected against (reduced babies). It still occurs in all sorts of species.

    What this means is that around 2/3rds of humans are strictly monogamous. Around 1/3rd of humans are promiscuous or partially promiscuous. These are instinctual behaviors that can be overcome somewhat by cultural norms. On an individual basis, for every 3 people you meet, one instinctually finds sleeping around to be their “normal” behavior.


  • My parents and grandparents taught me how to go bankrupt…

    Step 1: Mortgage inherited assets to follow the latest fad.

    Step 2: Make no profit but spend tons money.

    Step 3: Accept government handouts right and left but still lose money.

    Step 4: Go bankrupt and lose everything you inherited.

    Step 5: Blame everyone else for your own stupidity. Extra emphasis on people with darker skin color.






  • My wife has a couple graduate degrees on this subject. This is one that I got to be the unwilling editor on her papers for.

    Its a lack of understanding how students need to learn the information: memorization by usage versus memorization by rote.

    Memorization by rote: This is the old school method of teaching. You memorize random facts figures with no context or usage. Its a bit of standalone information that is often not useful. Memorization by rote leads to kids that can say all of the letters but not recognize the symbols or associated them with sounds and words.

    Memorization by usage: This is a much more effective method to teach. Its also much harder. This requires teaching the concepts and systems and linking the information together. You memorize the same information by repeated usage but it’s in context. It takes a ton more skill to teach this way because you have to engage the student through the entire process, repeatedly.





  • Where on the plant are the leaves yellowing?

    My first guess would be transplant shock. When the roots are damaged the plant has heal them. The plant needs to uptake nutrients to repair the cells and grow new tissues. The problem is the roots are damaged and plant struggles to pull nutrients from the soil. So the plant moves mobile nutrients (like Nitrogen) from older leaves to the new growth.

    The solution is usually to give the plant some fertilizer and wait a few weeks.

    “Regular” peas are are still harvested immature only at a later development stage. Fully mature peas are very hard like a dry bean.

    Sweet corn contains gene mutations that reduces the sugar to starch conversion in the kernal. So the sugar builds up in the kernal instead. The varieties are classified by the gene or combinations of genes they contain (su, se, or sh2). When the seed is fully mature and dry the seed looks like a raisin because of the lack of starch
