You did not seem to have too much trouble.
You should not hold your politics as your religious. Science
too. You get as angry, except for the murdering part, as the
muslins do when you challenge the Koran (probably misspelled
What should be a fun conversation between friends over this

True, but the increasing use of it in North America depressed the
price of sugar everywhere. And, as far as I know, sugar has become
ubiquitous in prepared foods just about everywhere.
I *should* have mentioned television, which is not only an extremely
passive 'activity' but also encourages an appetite for processed high
salt/sugar foods through advertising. (It also offers, for the most part,
an extremely poor model of 'real life' and unreasonable expectations of
what a 'normal' lifestyle would be.)
Television is also associated with metabolic syndrome (pre-T2 diabetes):
Sitting, especially sitting passively in front of a television, is bad for your
I thought there was a whiff of understanding there.
You have to remember that that scientific nolidge is not a broad agreement

Yes, his theory is NOT something that was handed down from
an Ultimate Authority as Revealed Truth. Darwin knew nothing
of genes, for instance. Modern evolutionary biology includes
population genetics. The entire field of Evolutionaly Developmental
Biology (Evo-Devo) is post-Darwin. Punctuated Equalibrium.
There is a great book about evo-devo (made into an okay but
sort of rushed television series) /Your Inner/ Fish by Neil Shubin,
which I highly recommend.)
It began before the improvement in sanitation.
Doh! That was my very point!
"This distribution is now thought to have been caused by recent natural
selection favoring lactase-persistent individuals in cultures in which
dairy products are available as a food source"
That's *exactly* what they are claiming. The human life span is
unusually long (for a mammal of their body size). Menopause is
unique. What selective force could explain how human social groups
which support populations of elderly, *post-reproduction* adults have
become the most successful?
If you want an example of the value of elderly individuals in another
long-lived species, consider the African elephant:
As for humans (sorry, this is behind a pay-wall):
Lyman Briggs College, field of concentration was mathematics.
My course of study at Lyman Briggs included chemistry, physics, and
biology. Also the history, philosophy and sociology of science were
standard requirements for Briggs students. It was a very interesting
place to be in the early '70s.
I had elective courses in horticulture, paleontology, physical geography,
psychology and anthropology at MSU. (My idea of fun!) I also took
an engineering class (mechanical drawing) as an elective.
Engineering and science are related, but they involve rather different
ways of thinking.
Tons of fun stuff. Thank you for writing. I have gone
over your references several time and will do so some
more as I have time.
Did not realize Darwin did not know about genetics.
Mendel came much before him, but apparently, was
not widely read. It is amazing the painstaking
research Darwin did without knowing genetics.
What strikes me about granny is that humans, orcas,
etc., survive and thrive because of socialization.
Ordinarily the "economy" brain is reserved for
animals that don't socialize. Eat and run. For
those that socialize for their survival, they get
the big brains.
To me, if you didn't figure out how to get your
tribe to work together as a cohesion social group,
you would have a distinctive reproductive disadvantage
to those that did. Again to me, that is the reason behind
elderly humans. They knew how to do things and taught
the young. If the young did not learn, they couldn't
grow old enough to reproduce. I do not see where
menopause helped this, especially since most never
reached it. Do you really granny or grandpa, if they
even lived that long, would not have acted the same way,
menopausal or not?
We may have the luxury in modern times of sending
and annoying elderly parent 3000 miles somewhere else
"where they get their own room", but Grok did not.
You worked it out or you died.
By the way, orcas (mammals like us) live into their 90
in four generation pods (tribes). They figured it out
(how to thrive from socialization). No clue if the
female go through menopause. If they don't, it would
seen to me that it would shoot the menopause theory.
Also, there are things that can't be account for with
evolution. If I am not mistaken, Darwin actually
wrote a paper on it. In science, todays truths are always
tomorrows falsehoods. It will be fascinating to see
what science comes up with to replace evolution.
(And, what replaces that theory too, should I live
Epigenetics: fascinate field of research!
Passing traits down from your parents was unheard of
a few years ago. Saw a documentary on Swedish
records where to kept track of such and it transpires
that a famine would send epigenitic expressions to
put on weight for two or three generations. (I forgot
exactly how many.) Does explain why mothers who
are immoral enough to diet when they are pregnant
wind up with fat children. Their children too.
With our American Indians, they are being poisoned
to death by carbohydrates. The Washoe, were I live,
look like they are about to explode. There is no epigenitic
and/or genetic mutation to protect them. And, they have been
exposed to European food for hundreds of years. Returning
to tradition diets heals them. (There are lots of references
about that out there. Let me know if you want me to dig
some up for you.) There certainly has not been
any getting "use to it". Just keeps killing them.
The addiction factor is something to behold!
Humans are just not showing any accommodation to
unnatural level of carbohydrates. Our Indians certainly
are not. Any mutation to help this has just not shown up.
Again, because carbohydrate poisoning kills you after
And, although the American Indians are more susceptible
to carbohydrate poisoning than Europeans, Europeans
are certainly not exempt from it (including me).
Watched a great documentary as to why humans are
different colors. The researcher was trying to find out
the association of ultra violate light and skin color
and why skin cancer was not a factor because it
did not affect natural selection as skin cancer
killed you much after we reproduced (like diabetes).
She did figure it out -- it had nothing to do with
skin cancer. And it was all about natural selection.
Fascinating study in evolution. I won't say what
in case you want me to find the documentary (Netfilx/roku)
and I don't spoil the show for you.
Thank you again for the wonderful letter.
Fun read. Thank you.
Engineers are builders/creators. Scientists study things.
One of the things that drive scientists crazy about us
is that we use formulas in the range we need them. We
really don't care so much if they are inaccurate out
of were we need them to work.
By the way, the engineer in me loves to cook. I think
all aspiring engineers should take a cooking course. Teaches
them how to think and plan properly (project engineering).
As someone who makes jellies and jams and tomato sauce from raw
ingredients and used to bake bread, "huge amounts of time" is *entirely*
accurate. (I've even killed and processed chickens and ducks, and can only
imagine the amount of work involved in butchering a hog, rendering lard,
making sausages, managing a smoke house, etc.)
You can visit "living history" sites where you can see demonstrations of how
people used to live. Greenfield Village is in my neighborhood (1880s farm
lifeat Firestone Farm), then there is Plimoth Plantation in Massachusetts
(17thcentury colonial and native villages), just to name two.
>These days few people know how to cook from
I've had people look at the produce I buy and ask, "what the heck you do
I recently helped a lost looking woman clutching a recipe, who apparently
had no idea where to even *start looking* for arugula. (I hope the recipe
spelled out everything else in sufficient detail, so as not to discourage her
interest in cooking!)
Snap! I still do most of those things in the season for the doing of
them. :-)) I particularly love jelly making and just yesterday was
looking at a commercial, 'proper' jelly bag and stand. I've always just
used an upturned stool and a calico cloth to do the overnight dripping
(I think that's 'muslin' in USian but not sure).
In the end I decided that the stool and calico square had worked for
decades so buying a commercial one was an indulgence on my part.
I don't kill ducks any longer as I have none now, just chooks (chickens
and can only
Yep. Makes me tired to think of it. We just had a steer killed but got
the lcoal butcher to pack it so we could give one side to the offspring
and we kept the other side. Just packing half a big steer into the
freezers was a sizeable job.
I love places like that. But as an avid spinner, sometime weaver, avid
knitter and active user of my treadle sewing machines, I'm probably
considered to be a living olde, timey madwoman in the way I choose to
live my daily life. I prefer to use my treadles over my modern machine
but the treadles won't (sadly) do a zigzag.
LOL. A friend was telling me that there had been a run on the shops in
her local area because of some threat of shortages (road transport
strike I think it was) and she and her husband couldn't get near the
shops for a couple of days. She said that all that was left were the
things that they would have normally bought so they proceeded to do
their usual fortnightly shop of stuff like lentils, chick peas (gabanzo
beans) porridge, wholemeal flour (Graham Flour) etc.
Snort. Poor woman.
I always have a new row of rocket (arugula) coming along as it's one of
the greens I love and it grows here all year round and best in the
colder months. Living rurally I need to always have green growing in
the garden as greens are the thing that always look tired and well
travelled in our small local grocers.
Engineers are over-represented in the ranks of some antiscience movements
such as creationism where they insist that they understand the science but
don't. If you have a look at talk.origins you will find many of the
educated creationists are in fields like engineering and mathematics that
sound sciency to the lay person but don't actually employ the scientific
That sounds like one of the engineers we know. Uless one is in the mood
for a rollicking good argument, the topics to avoid with him are
ecology, pesticide usage, industrial chemical usage, solar and wind power.
Don't pay attention to average life-spans. Especially in the
distant past, they were heavily influenced by high death rates
at young ages. Make it past infancy and childhood, and a
female had a reasonable chance to spend a few years as a
menopausal grandma. (You should have picked up this info
from one of your paleo-diet sources already.)
Human lifespan took a hit after the transition to agriculture,
but then increased quite a bit (and increased *before* the
modern hygiene and medicine arrived).
The advantage of menopause (which great apes do not
experience) is that it frees older human females from the
burden of continued pregnancy and lactation. The article
behind the paywall (and others I have read) have actually
concluded that grandmothers increase likelihood (and total
number) of grandchildren that reach adulthood. And that
is its selective advantage.
Science is unlikely to replace evolution. It has been
demonstrated to happen. What I will refine are
theories about how and when it happens. And
here is a clue for you all: lots of change is random
drift. At some point, it may become relevant to
survival, but very often it is not. It is just change.
And, second clue: EVERY living creature on earth
is just as evolved as any other.
Theories about *abiogenisis* (the origin of life), on
the other hand, are quite likely to remain unsettled,
unresolved, and subject to major rethinking.
Humans are not just their genes and gene methylization
pattern, either. You could take a certain point of view
that we are merely carriers for large colonies of bacteria.
I have a gut feeling that many answers to modern health
issues are going to involve finding the right strains and
proportions of bacteria to keep us healthy.
AWESOME! I searches for that and got squat.
This gives a lot more credence to the grandmother theory.
Although, with or without menopause, I don't think
granny would have been a competitor. Everyone had
to have everyone else's back. It was not like in
modern society, where tribe has been lost.
By the way, I have the American Cheyenne quote on tribe
and family if you would like it. Some powerful stuff.
That explains a lot. It is fascinating how well Darwin
did without this layer of the onion. My opinion, I think
Mendel's and Darwin's work both complement each other.
Mendel was accused of falsifying data -- his results were
too clean -- but he has been cleared. Peer review can be
a harsh process.
I found other references to this too.
The Longevity: New data indicates that the average lifespan
of the Orcas is between the 50.2 and 80.2 years for Females
and 29.9 to 50 years in males. Approximately 45% to 60% of
the young that are born wild die before reaching the one-year
Note that the above link did not reference their assertions, which
is a huge no-no in the scientific and engineering community (not
as bad as getting caught falsifying data).
The infant mortality in the above is heart breaking for a
sentient (my opinion) creature. When one of the members of
their pop (tribe) dies, they are heart broken. The screaming
and crying is something no one would want to listen to who
had a heart.
The 90 years thing came from a documentary I watched on Netflix.
Someone may have had an agenda mixed into their work. (I like
orcas too, but don't fudge your data.)
