Is the real planet of the apes coming soon?

Stand by for apes entering the Stone Age

As we saw with tool use, many claims [about ape behaviour] are phrased essentially as predictions that the primates are in the process of developing a culture like that of humans, rather than behaving as they have, largely unnoticed, for tens of millennia. For example, we were told earlier this year that “Apes may be closer to speaking than many scientists think. Koko, the gorilla who has lived with humans for forty years can “control her larynx enough to produce a controlled grunting sound.” While Koko is a very accomplished gorilla, she doesn’t seem to be progressing toward human speech, and it is unclear why she would need to.

Similarly, we are told that bonobo infant noise points to the origin of human language and can challenge “how we think about the evolution of communication and potentially move the dividing line between humans and other apes.” Really? Despite having done nothing similar for bonobos in all this time? We also hear that monkeys recognize the basic structure of language, but they do not go on to but develop a language either.

In any event, when primate researchers say that bonobo infant noise challenges “how we think about the evolution of communication and potentially move the dividing line between humans and other apes,” who are the “we” who are challenged? They themselves seem quite convinced that there is no significant dividing line, no matter what the state of the evidence.

And their position cannot easily be assailed. They can go on looking for evidence indefinitely, and the developments in ape consciousness that would prove them right would, if they ever occur, be millennia in the future.

Meanwhile, subsequent research did not support one claim that chimps learn other troupes’ “languages.”More.

Lots of people have to want to believe this stuff. Otherwise, it would be challenged more.

Question: Couldn’t we care about apes, humane treatment of apes, and their conservation without all the “just like us” nonsense? Do current stats show that the nonsense is really helping numbers?:

Gorilla and chimpanzee populations in Central Africa continue to decline due to poaching, habitat loss and disease. National parks and reserves in six range countries protect only 21 percent of western lowland gorillas and central chimpanzees, according to a new report.

Converting carnivores to herbivores

By knocking out plants’ don’t-eat-my-seeds chemicals

From The Scientist:

Researchers are converting carnivores into herbivores in a bid to make raising animals such as alligators, trout, and salmon more sustainable.

It’s no mean feat turning a meat-hungry predator into a plant eater. The American alligator is an apex predator of southern waterways from Texas to the Carolinas. In the wild, adult alligators eat fish, frogs, turtles, snakes, birds, and just about any small mammal they can catch. On alligator farms, the animals chow down on fishmeal and oil processed from wild stocks of sardines, anchovies, and other forage fish harvested from the open ocean. While populations of these fish species have plummeted over the past two decades due to intense fishing pressure, global demand for fishmeal and fish oil has continued to climb, and prices have quadrupled in recent decades. Now, researchers are searching for alternative feed ingredients for alligators and other carnivores farmed for human consumption.

Talk about the lion lying down with the lamb … the alligators were switched from fishmeal to vegan with only a slight reduction in growth.

Scientists have learned that fishmeal and fish oil contain a balance of about 40 nutrients, including vitamins A and D, amino acids (such as methionine and lysine), minerals (such as iron, zinc, selenium, and iodine), and long-chain fatty acids. More.

The trick is to balance the nutrients so that the ‘gator version of Boost is equivalent to the nutrients from whatever the ‘gator can catch.

Get this:

The most common ingredient today in aquaculture feed is soybeans. Soybean meal is widely available, nutritious, and relatively inexpensive, usually costing about one-quarter of fishmeal’s price. But soybeans, like many other plants, have evolved chemicals called “antinutrients” to discourage predators from consuming their seeds. Soybean’s antinutrients include lectins, oligosaccharides, and trypsin inhibitors. Each anti-nutrient might be harmless alone, but together they can cause an inflammatory condition in some fish called intestinal enteritis, which can reduce growth and produce additional waste that must be cleaned up.

They just happened to have evolved “antinutrients” and a chemical ecology balance was somehow struck.
