Just to preface, I am a plant breeder/geneticist with extensive experience in interspecific crosses in multiple species - all practical. This discussion should definitely be finished over some a few drinks.
- Comment on Forbidden Fruit 5 days ago:
Out-breeding depression primarily results in a decrease of fertility and infant mortality. So although it is occasionally observed in surviving offspring, in general it is much lower probability.
Also the neandertal crossing was deleterious it would be much lower percentage in modern humans. It also would not have come from multiple crossing events.
- Comment on Forbidden Fruit 6 days ago:
Usually these issues are caused by mitochondrial DNA not nuclear DNA. Mitochondrial DNA is only passed on from the female. So if there is an incompatibility, it’s usually completely lethal to any offspring.
So a HMNF coupling could not have been possible because of the neanderthal’s female mitochondrial DNA.
- Comment on Forbidden Fruit 1 week ago:
If I had to guess the successful crosses were potentially much healthier than either parent line. Heterosis (hybrid vigor) would likely be pretty extreme in genetic lines that has been isolated by 300,000+ years of time. Of course the degree of fertility was likely lowered due to genetic distance. Once the initial cross was made however, back-crossing to either species by the hybrid would likely be much easier.
Many of those ancient stories about individuals with super strength and size etc could have likely been based upon these crosses.
The evidence is showing neadertals never truly died out. Their smaller population bred back into the modern humans who came later.
- Comment on Forbidden Fruit 1 week ago:
There is a few different potential reasons as well as sexual preference.
Genetic incompatibility - the interspecific cross could only occur one way.
Genetic bottlenecks in the neandertal lineage. A high inbred coefficient could have decreased the neandertal females overall fertility (high deleterious alleles load). This could also cause a rapid reduction in the percentage of neandertal DNA in a mixed population.
Maternal behavior - Neandertals females might not have cared for hybrid offspring appropriately. This could be for anything from milk production requirements to differences in physiological developmental rates.

It’s normal to cite your own work if the new paper is a continuation of that research. A references or three is normal and expected.
When somebody publishes a bullshit paper that is eventually withdrawn, every subsequent paper citing the fraudulent work can also be withdrawn as being unreliable.
A sign it’s all bullshit is when you see the majority of the citations for the paper from the same author. This usually doesn’t pass peer review anymore. In hyperspecialized fields with few researchers, they commonly get a little creative on the introduction section to include other authors.

Potatos are very destructive to the soil.
They have to be dug up (lots of cultivation). This breaks up the soil structure causing all sorts of issues with porosity, nutrient and organic material loss.
Because of the diseases and pest that attack the growing tubers, growers use fumigants/biofumigants. These are indescriminate killers that wipe out all sorts of insects, fungi, nematodes, and bacteria.
Potatoes leave very little organic residue behind when the tubers are harvested.
Any crop that follows potatoes suffers from a “yield drag” for 2-3 years as the soil recovers.
Out of the all starchy foods we eat, potatoes and sweet potatoes are the worst for the soil.

Its a fucking stupid and manipulative question for the employer to ask. No employer should give a fuck if somebody took a couple years to travel, take care of family, or just couldn’t find a job.
What they are really asking "Are any of the time gaps in your job history, a job that you got fired from with cause? "
Instead of being little shits about it just ask the actual question straight out. The shock value of asking a real non-bullshit questions in an interview has paid off many times for me when hiring.

- Comment on Why??? 🍅 1 month ago:
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.
- Comment on Brand new bag 1 month ago:
When I was on the travel circuit I always did a carry-on and a backpack. The backpack was usually full of job related equipment so there wasn’t much room for clothing etc. The carry-on was enough for trips of up to 2 weeks.
As I was in agricultural fields and hot temps everyday in all sorts of countries, full changes of clothing was required plus at least one laundry stop before I came home(phytosanitary rules and all). My carry-on often weighed in at 40lbs or more on those trips.

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.
- Comment on Humans rank between meerkats and beavers in monogamy ‘league table’, but sheep are sluts. 2 months ago:
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.

- Comment on I need to vent about plastic milk jugs 2 months ago:
It adds flex to the container for variations of atmospheric pressure. It’s what they mean by the fill levels.
Milk containers are filled by weight. The exact volume of the liquid can vary slightly based upon the atmospheric pressure.
If the container has no flex the top will pop off or the sides will crush in with pressure changes say when a truck drives over a mountain pass to deliver the milk.

My favorite was to take a screenshot of the desktop and set it as the desktop Then put all of the icons into a folder. Most people I left the folder on the desktop. The IT guys, the folder was then hidden.

Non-destructice hijinks were highly encouraged at my first job. It was a way to encourage people to remember to lock up their computers when they stepped away.
So mouse button settings were often reversed, hotkeys were mapped, desktop backgrounds were modified, and basically every other non-destructive computer prank was pulled.

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.

The USDA-NASS is responsible for making an estimate of the number of corn cobs in the U.S. Most other countries have similar organizations.
To do so they send surveys out to ask farmers what they think. The farmers answer completely truthfully because lying would inflate the prices they get on their corn cobs.

Corn to teosintes GMO contamination is also huge issue especially in southern states.
20+ years after a failed introduction of GMO RR wheat, they are still finding it in fields.

The so called terminator gene was developed in and to attempt to limit the spread of GMO genes into the wild populations. It was a USDA-ARS program. Not their best work but it would have prevented today’s clusterfuck of contamination.
