Do you mean Hellen Keller? Anne Frank was the girl living in the attic during nazi occupation in World War II. Helen Keller was blind and deaf and, to my recollection, wasn’t able to communicate until adulthood when a teacher came along to teacher sign language.

My recollection is you need to “talk” to each animal once a day, every day.

Ukrainian crews say the fundamental problem is that the Abrams were built for advances aided by air power and artillery, which Ukraine lacks.

Russia, meanwhile, continues to make heavy use of drones in its attacks, which the Abrams struggle to defend against.

Relevant Section on the genetics:

For the study, the researchers took blood from five of the cats, which had been adopted, and conducted a DNA test on four of the felines, which turned up no genetic mutations associated with white fur.

They then performed a whole genome sequencing for two of the cats, and this step turned up a deletion in what’s called the KIT gene, which can encode whether white will turn up in a feline’s coat (scientists have also connected variations in the KIT gene to piebald patterns in various animals like horses and mice.)

“In summary, comparative data from other species and genotype segregation analysis support the newly discovered KIT region deletion as potentially being a cause of salmiak coat color in cats,” the researchers conclude.

Same with golfing, bowling, darts, etc. I think part of the enjoyment of these types of sports/games/competitions is to see how close to perfection you can get.
