Now, we all know that parenting is a tough job. Let’s list down some qualities of a good foster parent:

1) Provides food
2) Patience
3) Time
4) Care
5) Commitment
6) Responsible
7) Flexible
8) Resourceful
9) Love
10) Growth and Development

How about being a foster parent to a child who is biologically, psychologically and emotionally different from you?
In that case, how do we determine what makes a good foster parent? Are the criteria similar or not?
In the first place, could animals have raised humans? Do we see only what we want to believe? Or, are animals merely just companions of these children?

In April last year, I watched an interesting national geographic documentary about Feral children, with particular focus on Ukrainian female Oxana Malaya, who lived in a kennel with mongrel dogs  and Ugandan teenager John Ssebunya, who was reportedly taken in by a troupe of Vervet monkeys when he was aged just four.  Inspired by the documentary, I decided to write a post about it! Feral children are children who have spent much of their formative years in the wild, due to reasons such as blatant neglect or abandonment by their parents. It is useful to note that they live without any contact with other humans for a significant period of their lives. This impeded their developmental progress as they missed the critical period for language acquisition from birth to around five years old. Therefore, being deprived of stimulation, most of them never acquire the ability to have normal speech patterns or hold a proper conversation. Even if they are rehabilitated, some never quite adjust to the society and even show signs of wanting to go back to the original environment they once belonged.

I know the topic of feral children is somewhat controversial but is especially intriguing to me. Sadly, there is not much serious scientific data and research done on this topic. Practically nothing is known about the life of a feral child before his or her discovery. According to Bettelheim, there is no such thing as feral children. He believes that humans imagine too much and that these children “stopped existing as human beings” in order to protect their lives. He prefers to take an extreme view that these children have some form of psychological disorder, for instance, he explained that Amala and Kamala, two wolf children has symptoms similar to schizophrenic children who were insensitive to heat and cold.

In the documentary, some scientists cast doubts regarding this topic. Is it was a genuine case of paternity care for the feral child by the animals or a case of the child being an outcast, eating leftover food and cohabiting with the animals sorely on survive instinct? In the media, there are many uncorroborated, documented feral children who have been portrayed in such light that the “foster parents” such as wolves or dogs took the children under their wings and took care of them. Many cases involve wolves as “foster parents” due to their intelligence and nurturing ability. One famous case include two wolf girls, Kamala and Amala who remained all fours, bite others when provoked and consume raw meat as their diet. What the media fails to mention is that these children are as likely to, due to basic survival instinct, follow and learn from their “foster parents”, eating leftover food and living with them, behaving more like a social outcasts than part of the “family”. In other words, perhaps it is not that animals raise children but that somehow, animals overcome their aggressive predatory behaviour and are persuaded to ‘help’ or allow humans to co-exist with them. This can be seen in the case of John in the documentary: Observing the boy’s interactions with a group of the primates, Professor Candland concluded that John had spent time “living among” the animals, “but there was no way to know for how long or what they did for him. He points out that “there is no evidence that any species of animal will provide for and raise a human infant.” The Vervets certainly didn’t care for him in any real sense.” In the documentary, John is seen to be able to point to various places where he forages with his monkey friends and has a conviction that he is looked after by them.

I have several questions: Is it possible for a child to even survive under such unfavourable conditions? Humans, unlike animals in the wild, is fragile and extremely dependant during infanthood and early childhood. It seemed to be that it is highly unlikely animals in the wild possess the necessary qualities to take care of a being as fragile as infant/young child. If the feral children cases are true, proving the possibility of such phenomenon occurring, why aren’t other animals taking care of other lost animals that are different from them? One example of such occurrence is mentioned during lecture, where we learnt that brood parasites are birds that lay their eggs in the nests of other species (the “hosts”) have their offspring raised by the host parents. However, this is merely a form of ‘cheating’ but in the case of feral children, animals are thought to be deliberate in their intentions to’ raise’ the human child.

On top of that, one questions how do they interact in the wild? In other words, how do these animals (‘foster parents’) communicate with humans? Do they rely on chemical, audio, visual or tactile channels of communication? Does the behaviour of one individual affects the behaviour of another individual and generally improves both participants’ fitness? How do these children take on particular characteristics of their ‘foster parents’ as seen in Oxana who barks and crawl on all fours before she was rehabilitated? Do they show a marked sexual attraction towards the same species of animals?

At the end of the day, we can only speculate and let our imagination about animal behaviour run wild. We cannot conduct any experiments on this topic and we also cannot interview these feral children as they cannot speak and normally die at a relative young age. I shall end this long post with a quote by EL Doctorow:

“When ideas go unexamined and unchallenged for a long enough time, they become mythological and very, very powerful.”

Tigers and Pigs nurse each others’ kids

Pigs nurse tiger cubs and vice versa

Talk about predator and prey relations!!

Pigs are supposed to be a part of the tiger’s natural diet, but here we see a total reversal of that relationship. Tigers and pigs live in an prey predator type of relationship in the wild, but it seems that this type of relationship is lost when the maternal instincts take over. It seems that maternal instincts are predominant and are stronger than the prey predator relationships when animals are kept in captivity. Animals in captivity are beginning to lose thier natural instinctive behaviors as the population of animals in zoos become natal, as most of the population are born and bred within the premises of the zoo.

Sriracha Zoo in Chonburi, is Thailand’s most successful tiger-breeding zoo largely due to the discovery that tiger cubs nursed by pigs grew up calm, unaggressive and more suited to life in captivity. Now all of the zoo’s 300 tigers are raised this way. 

 

And it happens both ways…. Tigers nurse piglets as well! This is truly revolutionary as the animals seem to willingly act as surrogate mothers for the other species. The cost benefit analysis does not apply in this case as the animals were in captivity and we are unable to see any feasible benefits from them nursing each other’s kids. This is truly sensational.

The field needs to be further studied as more research needs to be done as to why animals let thier maternal instincts take over thier natural prey predator relations. WHat is the mechanism driving this?

One of Nature’s Best Architect!!

We are well familiar with the Eiffel Tower, Sydney Opera House and even the Great Wall of China. But as impressive as these human architectures are, we have equally (or some would say, even better) awesome architects in nature: the Termites.

Certain species of Macrotermes and Amitermes build huge mound nests which are more than 10m in height. Amitermes are also known as magnetic termites due to the way they orientate their flat and broad protruding mounds which are along the north and south axis of the Earth. Unlike us, in which we can employ the help of heavy machinery and tools to aid in construction today, the termites built their enormous mounds solely relying only on their own strength. Bit by bit, each worker places a “brick” of building material, consisting of nothing but the soil in their vicinity, probably mixed with a bit of their saliva for cementing purposes.

Why the high and conspicuous mound you might ask. The reason is ventilation. Nests like these house large colonies of termites, some reaching a population of a million strong. With such numbers in an enclosed place, it can get truly hot. Acting as a chimney, the protrusion draws away heat and exchanges it with cooler fresh air. In addition to a chimney, these mound nests are fully equipped with a “well’ at the bottom in which the termites draw precious water.

The designs of these mounds serve several functional purposes like thermoregulation, ventilation and hydration. Moulded and fine-tuned overtime through evolution, they stand the trial of time. It is indeed fascinating to see such elaborate structures constructed by these little creatures working in great unison with such efficiency. But exactly how it is they communicate to each other to achieve such cooperation to the most minute of details, we don’t yet know.

The Birth of Polar Bear Cubs!

Mother Bear and her Cub

Mother Bear and her Cub

Looking at the massive size of polar bears (males stand from 8 to 11 feet tall and generally weigh from 500 to 1,000 pounds, but may weigh as much as 1,400 pounds. Females usually stand 8 feet tall and weigh 400 to 700 pounds, but may reach 700 pounds), one can never imagine that when born, they are blind, hairless and no bigger than squirrels! Check out this link to catch a glimpse of a cub just born: Birth of baby Polar Bear

Breeding usually takes place in April. However, the embryo will only develop if the mother has enough food supply to sustain herself and her developing cubs throughout winter. Pregnant females will then look for sites on slopes on land or sea ice to dig dens to give birth and to spend the winter. This usually takes place around October or November. The den is usually just a single chamber slightly elevated from the entrance tunnel to prevent warmer air from escaping out. It is observed that the difference in temperatures between the air inside and outside the den can reach up till 20 deg Celsius. ‘The den’s primary role is to provide a secure environment for the gestation and bearing of young. However, following den emergence, continued den residence by cubs is beneficial in that it provides opportunities for acclimatization to the harsh arctic environment, development of locomotor skills, and an increase in body weight and overall size.’ It is amazing how a simple hole structure can serve so many functions!

Usually 2 cubs are born each time around December or January. As mentioned earlier, they are quite tiny when just born. However, they grow rapidly by drinking milk high in fat content provided by the mother. After which, they will leave the den around March or April, which is during Spring. Check this link for the emergence of the mother bear and her twin cubs: Emergence from the den! The cubs usually remain with their mothers for about 2 years. Therefore, most female bears breed just once every 3 years.

Another interesting fact about them is that each individual hair on a polar bear’s coat is actually a clear hollow tube and it is because of the sun’s reflection that they look white. During summer months, the bears shed their coats to grow new ones which look pure white. However, they turn yellowish by the following spring because of the sun’s rays.

Related journal article: Stirling, A. & Ramsay, M.A. 1990. Fidelity of female polar bears to winter-den sites. Journal of Mammalogy, 71(2):233-236.

  • talks about how it is only the pregnant female polar bears that live and remain in their dens throughout winter and that they do not live in the same den more than once. Males polar bears and female bears who are not pregnant are actually active during winter. The distribution of dens in the Arctic is also investigated.
