Bottlenose dolphins come out to play

New research shows young bottlenose dolphins (Tursiops truncatus) learn and develop through play, just like human children.

Anyone who has a dog or a cat will know that they play, particularly when they are young.  Play is an important way of testing and understanding the world about them.


Problem solving skills

Play also creates scenarios, and tests positions and possibilities.  It develops prowess and agility.  It rehearses action,  and with different behavioural strategies and methods, individuals can develop a variety of problem-solving skills that can be applied across different contexts. It enhances stimulation and sensory experience, but above all,  play is by its nature 'enjoyable'.

Cultural learning

Like humans, dolphins have big brains.  Play is also vital for  developing the complex neural circuitry of a dolphin's  brain, a great deal of which will be forming after birth and in early life.

Previous research suggests that complex social and cultural characteristics, such as hunting together, developing regional dialects and learning from observation, are linked to the expansion of the animal brains.

Dolphins also learn by watching others play.

Dolphins at play

Researchers writing in the journal Behavioral Processes observed the play behaviour of 30 dolphins, ranging in age from one to 24. Behaviours were categorized as either social or solitary, which also included observational play (watching others play) or parallel play (independent play close to others).

Like many species, play behaviours were found to decrease into adulthood. Despite the social nature of bottlenose dolphins, calves (1-3 years) and juveniles (4-7 years) engaged in solitary play more often than social play, suggesting it may help to teach individuals the skills they need to engage with others.

Like human children, dolphins play with their age group

Young dolphins also preferred to engage in social play with dolphins of similar ages, rather than adults.   But as calves age, "their preference for playing with peers of the same age becomes less characteristic of their play interactions, and instead older and more experienced individuals are selected as play partners."

The researchers say understanding these behaviours could lead to better social environments for dolphins in managed care, but it also adds to our understanding of the role of play.

through development of a more diverse behavioral repertoire, stereotypical behavior and behavioral deficits should also decrease, resulting in more natural and enriching lifestyle.
It might also lead to a better understanding of creativity and problem solving.

The lion and the wildebeest

Birds flock, fish school, bees swarm, but social being is more than simply sticking together.  Social groups enable specialisation and a sharing of abilities, and enhances ability, learning and creating new tricks. The more a group works together, the more effective they become as a team.  Chimpanzees learn from each other how to use stones to crack nuts, or sticks to get termites.  All around us we see cooperation and learning in nature.  Nature is inherently creative.  Pulling together becomes a rallying cry during a crisis.  We have heard it throughout the coronavirus pandemic.  "We are all in this together", a mantra that encourages people to adopt a common strategy. In an era of 'self-interest' and 'survival of the fittest,'  and 'selfish gene', we lose sight of the obvious conclusion from the evidence all around us.   Sticking together is more often the better approach.  This is valid for the lion as it is also for the wildebeest.   We don't

Noise pollution puts nature at risk

 "I just want a bit of peace and quiet!" Let's get away from all the hustle and bustle; the sound of endless traffic on the roads, of the trains on the railway, and the planes in the sky; the incessant drone; the noise. We live in a world of man-made noise; screeching, bellowing, on-and-on in an unmelodious cacophony.  This constant background noise has now become a significant health hazard.   With average background levels of 60 decibels, those who live in cities are often exposed to noise over 85 decibels, enough to cause significant hearing loss over time.  It causes stress, high blood pressure, headache and loss of sleep and poor health and well-being.   In nature, noise has content and significance.  From the roar of the lion, the laughing of a hyena,  communication is essential for life; as the warning of danger, for bonding as a group or a pair, finding a mate, or for establishing a position in a hierarchy - chattering works.  Staying in touch is vital to working

Ian Duncan-Smith says he wants to make those on benefits 'better people'!

By any account, the government's austerity strategy is utilitarian. It justifies its approach by the presumed potential ends. It's objective is to cut the deficit, but it has also adopted another objective which is specifically targeted. It seeks to drive people off benefits and 'back to work'.  The two together are toxic to the poorest in society. Those least able to cope are the most affected by the cuts in benefits and the loss of services. It is the coupling of these two strategic aims that make their policies ethically questionable. For, by combining the two, slashing the value of benefits to make budget savings while also changing the benefits system, the highest burden falls on a specific group, those dependent on benefits. For the greater good of the majority, a minority group, those on benefits, are being sacrificed; sacrificed on the altar of austerity. And they are being sacrificed in part so that others may be spared. Utilitarian ethics considers the ba
