Together, mother and daughter grabbed the unlucky bird and proceeded to slaughter it with a swift machete strike to the neck. Every generation has to reinvent sex because the previous generation did a lousy job of teaching it. One of the more defining features of small-scale societies is the structure of their communities. While Westerners live in nuclear families with low birth rates, those in small-scale societies tend to have more children and live in extended networks of nearby kin. For instance, many Shuar now live in centros , or centralized communities.
Homes are often built around community centers or open fields, with clusters of families, commonly linked through a patriarch, living next door to each other. Many homes are still built in the traditional style, with bamboo walls and thatched roofs, inside which everyone shares one, big room.
This makes privacy a scarce resource and also means that much of life takes place in full view of the next generation and sometimes in front of the odd anthropologist. From an early age, most people—particularly young girls—are tasked with caring for their siblings, so by the time they are having their own children, they already have years of experience. This experience can prove useful because babies are confusing, especially at first.
Instead, our communities are structured around the nuclear family, with other kin largely absent, unable to offer guidance. That, coupled with the social and economic challenges of our labor system, make it difficult for knowledge to make it through the generational pipeline. And in some countries, such as the U. For example, in the recent past, mothers relied much more heavily on formula feeding: 3 out of 4 of babies in America were bottle-fed in the s. Perhaps this is a contributing factor to why only a third of American mothers make it through the first six months of nursing.
Compare the experience of American mothers to those of the Himba, an ethnic group in Namibia who largely survive by herding livestock. Virtually all Himba mothers breastfeed, and they make it look easy; women can be spotted multi-tasking—walking, chatting, eating—all while they feed their infants.
But work by Brooke Scelza, an anthropologist at the University of California, Los Angeles, has revealed that Himba mothers initially struggle with breastfeeding at about the same rates as American parents. This means they have consistent access to both direct care and, importantly, cultural information about early childcare. The importance of generational knowledge in early parenting is evident across an ecologically and geographically diverse range of other small-scale societies, such as the Martu of Australia, 7 the Hadza of Tanzania, 8 and the Efe of the Democratic Republic of the Congo.
The birth and care of a new infant is a family affair, with grandparents and siblings frequently present to help by sharing what they know. Humans will have a chance to prove their adaptability as the Earth undergoes unprecedented challenges in the Anthropocene, an era named after our impact on the biosphere. To learn what it takes to survive far into the future, astrobiologist David Another generational lapse in our cultural knowledge of parenting may have happened with sleep.
Even the composition of human breast milk suggests this mode of feeding is more natural. It is relatively low in fat compared to other mammals, meaning that humans are demand feeders—our babies nurse when they need to, even through the night. This is a world away from the average American parent, sleeping in a separate room from his or her infant, anxious as to whether their child will sleep. How did we end up with these norms?
Up until the 19th century, co-sleeping was widely practiced, even in the U. Industrialization, the medicalization of infancy, and the fear of coddling children changed our norms. Today, co-sleeping is being slowly reintroduced into our culture, but essentially without firsthand knowledge of how to do it. A t the other end of the human experience is death.
Among small-scale societies, funerary practices often involve whole communities. Funerary practices among the Shuar included laying out the deceased in hollowed-out logs and placing them in small houses, in which food offerings were made for two years. There's a results chart at the end, so keep track of how many apply to you:.
You don't struggle to stay disciplined; you struggle to prioritize. Your problem definitely isn't staying busy and on task. Getting going isn't an issue. Your problem is you have so many things you want to do, you struggle to decide what to do first. You think, I hope I get to When you love your work, it's like peeling an onion.

You don't talk about other people; you talk about the cool things other people are doing. What are they working on? Let's ask her how we can best leverage that. When you love your work, you don't gossip about the personal failings of others. You talk about their successes, because you're happy for them which is also also a sign you're happy with yourself. You think about what you will say, not how you will say it.

And when mating season rolls around, male humpback whales will belt out amorous tunes to woo a female. Some research even suggests that males will start to weave complex syntax into songs to convey more information to a potential mate.
But, there are always other males ready to imitate successful song styles to win over their own crushes. Sea otters lie on their backs when they're in need of a deep doze, but their prone position also creates the perfect excuse to hold paws with their significant otter. Sea otters will either grab on to each other, or wrap themselves up in kelp, to keep from drifting apart at sea while they rest.
Sea otters are polygynous , meaning a single male can mate with several females. This usually results in fierce competition between males to land a female. Reproduction for seahorses is a delicate dance in which males and females aim to be perfectly in sync with each other.
Studies have shown that seahorse couples will court for several hours , swimming side by side to mirror each other's movements. The longer two partners are together, the more successful they become at breeding.
After mating, the male prepares to do what very few animals, including humans, are capable of doing for their lady. Male seahorses will carry up to 1, eggs in his pouch for about 45 days , leaving the females to relax until her babies are ready to be born. Together, they must jointly defend their feeding territory from other hungry fishes, showing that teamwork helps build stronger bonds with your loved one.
