Male monkeys prefer toy cars, females like dolls
Something seems wrong strange with this.

What seemswrong strange is how the statement that female monkeys fancied cooking pots might fit into this evolutionary speculation... hmmm... hmmm...
Upd: probably this was because the cooking pots were red, and the authors of the paper decided to spin their conclusions somewhat.

The differences apparently date far back in evolutionary history to the time before humans and monkeys separated from their common ancestor some 25 million years ago, according to Gerianne Alexander, a psychologist at Texas A&M University in College Station, who led the experiment.
"Human evolution has created two different types of brains designed for equally intelligent behavior," Richard Haier, a neuroscientist at the University of California-Irvine, wrote in the journal NeuroImage.
Variety of toys used
In the monkey experiment, researchers put a variety of toys in front of 44 male and 44 female vervets, a breed of small African monkeys, and measured the amount of time they spent with each object.
Like little boys, some male monkeys moved a toy car along the ground. Like little girls, female monkeys closely inspected a doll's bottom. Males also played with balls while females fancied cooking pots. Both were equally interested in neutral objects such as a picture book and a stuffed dog.
People used to think that boys and girls played differently because of the way they were brought up. Now scientists such as Alexander say a creature's genetic inheritance also plays an important role.
"Vervet monkeys, like human beings, show sex differences in toy preferences," Alexander wrote in the journal Evolution and Human Behavior. "Sex-related object preference appeared early in human evolution," she said.
Alexander speculated that females of both species prefer dolls because evolution programmed them to care for infants. Males may have evolved toy preferences that involve throwing and moving, skills useful for hunting and finding a mate.

методологией эксперимента должен быть озабочен в первую очередь сам автор, а не мы. :-) Мы же можем лишь указать на то, что она хромает.
а) собирают не только ягоды,
это как-то влияет на смысл сказанного? :-)
привелите пример, что именно...
б) времена не всегда тяжелые.
в "лёгкие" времена, эволюционный процесс в лице естественного отбора
не имеет возможности закрепить такое полезное для выживание умение....поэтому, времена обильного кормы мы и не рассматриваем. В такие временна важнее становится стратегия поиска партнёра для репродукции.

Кроме ягод, можно собирать, например, орехи, которые можно хранить в контейнерах. Уж если даже белки и прочие грызуны в результате эволюции получили способность собирать и прятать пищу "на чёрный день"...

а в каких таких "контейнерах" белки хранят орехи, пардон?
дупло не есть контейнер, строго говоря...есть принципиальная разница между мобильным контейнером и местом, где можно зарыть или спрятать. Разница в восприятии функции, то есть, требующая некторого, пусть и небольшого, но изменения в мозгах.

Она может опрокинуть мир привычных воззрений. :-)))
PS так и не поняла, что добавляют орехи к ягодам в перспективе дискуссии...разве что в гастрономическом смысле. ;-)

Вот пример, когда рефлекс не обеспечен достаточной ёмкости памятью.
