A book accessible to all readers, whatever their level of numeracy ... an excellent introduction to what theoretical biologists get up to in trying to understand evolutionary and ecological ideas. ― NatureWhy are there only two sexes? Why do stags restrain their aggression in the middle of a fight? Can it ever pay to be nice in a world of selfish individualists? The answers, according to this informative and enjoyable volume, can often be found in games like hide and seek, poker, and the prisoner's dilemma. Author Karl Sigmund applies the ideas and methods of game theory and mathematical modeling to evolution, sex, animal behavior, and aggression in Games of Life, which was included in Ian Stewart's Top 10 Popular Mathematics Books in the Guardian (1/18/2012).
Starting with artificial life and self-replicating machines, the book examines pursuit games between predators and prey and draws parallels between games of chance and the randomness of molecular evolution. Other topics include the bizarre double games played by chromosomes and applications of game theory to animal behavior. Key topics appear at the start of each chapter, and endnotes provide references for readers wishing to seek out further information. This playful approach to understanding evolution and its central issues of sex, survival, conflict, and cooperation offers a captivating modern perspective on matters of life and death.

My Dogs Fought Over These!
Size: Large, Color: 6 Packs, Size: Large, Color: 6 Packs
Pack of 6. I specifically ordered a pack of them so each dog would have their own. They still fought over them. lol I only see two of them now because they have hid them from each other. So far, they are holding up well. Heavy enough to toss to them but light enough not to hurt them. Loved the variety of colors. Only issue I have is they are a little small for my mastiff but still giving it 5 stars because the ad stated it was for medium dogs.

Pawesome variety box!
Size: Large, Color: 9 Packs, Size: Large, Color: 9 Packs
I’m a big fan of this box of tug toys. My dog loves to chew and play tug-of-war, and these have been a great fit for him. The quality is solid, and one box typically lasts us around 6 months. He’s now 3.5 years old, so he doesn’t chew as aggressively as he used to, which helps them last even longer.
You get a great variety in this box. It’s honestly like Christmas for him every time I bring out a new toy. I usually grab a couple and let him pick. The different shapes and sizes keep things interesting, and he enjoys all of them. The toys are lightweight but very durable, even for an aggressive chewer like mine.
The material is made of thinner rope strands, but they’re tightly woven, which makes them ideal for both tugging and chewing. I also think the texture helps with his teeth and keeps them a bit cleaner.
I do keep an eye on them once they start to unravel, since I don’t want him swallowing loose strings. That said, it takes a while for him to break them down, so I’m comfortable leaving them with him when I’m not home.
I’ve bought several of these boxes over the years. For the price, it’s a great value—about the same cost as a single tug toy at most pet stores. My dog is about 55 lbs, and these are a great size for him. Even the smaller ones get a lot of use. His favorites are the looped ones and the ones with balls—he gets excited every time I pull one out.
I’ve tried other tug toy variety packs, and they don’t compare to this one. If you’re looking for a reliable variety pack for your dog, I’d recommend this one with confidence.

Revenge is sweet
Size: Large, Color: 14 Packs
The package arrived promptly. The puppy was ecstatic. She leaped into the pile of toys and went crazy. She tore through one after another. In mere minutes she devoured everything in sight. They never stood a chance. Within an hour or two she had consumed the entire pile of toys. Not to worry they had their revenge. She puked multi color string for days.
Overall the toys were fun just not durable.

Very very durable
Size: Large, Color: 9 Packs
So after spending quite a bit of money on toys for a 1-year-old long-haired dachshund because she's a very aggressive chewer I took a chance and bought this rope set and it's been 2 months she still has all her ropes everything I must say this is a very durable set well worth the money well worth the play time she loves tug of war these ropes are great for tug of war she has not chewed through any of them she has tried to take them apart which she had succeeded on one but I put a few knots in it and other than that I would recommend this rope set to anyone that's got a dog that likes the fat especially play tug of war or is a very very aggressive sure
