In walking limbs, the range of motion and control decreases as you move away from the body. In limbs made for manipulation things are less consistent. The human shoulder is a lot like the coxa in ants, it allows a wide range of movements in multiple dimensions. The elbow only allows one dimension of motion.
Ants have many more joints after that but they are like a stiff chain, no fine control. However, ants can flex their claws and expand and retract their foot pads.

Ants use their front two legs differently from the back legs. They may use these limbs to dig or hold objects in place when manipulating them with their mandibles. The coxa of the front leg is often longer while all of the other segments are shorter. Ants have a comb on their front legs which they use for grooming—
I don’t think the front legs are used for manipulation in enough ways to have that be their primary purpose but there is a distinction that makes them more like “arms”
from what I know, humans are rather unusual among mammals in the flexibility of our shoulder joints; dogs, horses, cattle, deer, etc, don't have nearly as much flexibility. Mainly it's aboreal (and some scansorial) mammals that have as much shoulder flexibility as humans. (And also bats. And I don't know about aquatic mammals.) The same is true of wrist and ankle rotation.

(I don't know if climbing arthropods such as tree dwelling ants would have greater flexibility of the coxa, but I would suspect they do.)
what's the name of the ant whose 2nd pair of legs are specialized to point dorsally "up towards the ceiling" away from the body, for travel in vertical tunnels, enabling them to brace their legs against opposite sides of a tunnel?
@llewelly They are also notable for being ranchers of scale insects— but not for nectar! They selectively eat them! Like humans with meat livestock.
I think I need to mention that many ants dig just like dogs ... using their front limbs to fling sand or loose soil between their back legs. It's very frantic, but also effective. I have some videos of Dorymyrmex digging this way. When mammals dig this way is it a stereotyped action, or somehow learned? What about with ants?
myrmepropagandist reshared this.
Can't find my video, but this one is better. It's "silver ants" or Cataglyphis bombycina
(no it's not speed up, they really move like that, when they spin in a circle they are looking for the sun so they will know how to get back to their nest. )

until now i always assumed they gnawed out a big clump of dirt and carried it away... this certainly better explains the debris mounds i see!
They use their mandible with wet soil. The "dog style" sand flicking is only for dry substrate.
Men are “significantly more romantic” than women, says The Times. New research combining the findings of more than 50 studies found that men tend to fall in love faster and more often, while women instigate 65% of break-ups and are “relatively unsentimental in matters of the heart”.

Men are not more romantic or sensitive. They see themselves as the center of every relationship, the woman as property who owes him loyalty and is never allowed to break off the relationship… and if she does, all failings are hers. Women ftmp, are too trusting, but we get over it and move on.

Dominic Lawson in The Sunday Times says the tide is turning on net zero. Trump has axed renewable energy subsidies, pulled out of the Paris climate agreement and “declared he will do everything to maximise hydrocarbon output”. China has increased wind and solar capacity last year, but its oil and gas output also hit a new peak and coal plant construction surged. BP announced it has stopped spending on new renewables, a massive U-turn on its 2020 policy. But our UK politicians remain unmoved.

Von Koch was regarded an eccentric (and his family was really rich).

Some Prussian ministry highly recommended the charts early on, which was probably a reason for their success.
The post-war charts were done from scratch by Carl Morian (the publisher's
brother) and one Georg Heldmann the successor of von Koch. All original
designs and plates fell victim to air raids.
I learned that teacher education began at the age of 16.
Many thanks to Henrik and Martin for helping me write the article and @Stadtarchiv_DA for providing original documents from the Morian estate that shows how the post-war charts were developed!

For me practice makes . . . well, not, perfect, but it's a lot better.
Setting aside time on a weekly basis to do it, even if it's just fencing off some time to not fill, means we make better use of it over time. For us, it's a weekly religious service with an afternoon of quiet time. I think it works better when part of it is in community but YMMV.
Our house lives and dies by our routines, so that may not be you.
