 Anthropocene Traps

The concept of evolutionary traps has been used almost exclusively for studying how non-human species respond to cues in anthropogenic environments [24–34]. Key examples include artificial human lights attracting insects, island species responding naively to the presence of introduced predators, and seabirds not being able to discriminate between the cues of marine plankton and marine plastics [34–36] (figure 1a). In the context of humans, evolutionary mismatch is a much more fr...

 Evolutionary Origins of Play

There are several kinds of speculation about the origins of play: (a) The first holds that play originates as a mutation and therefore an amelioration of dangerous adaptational conJicts. According to John Allman in Evolving Brains, this play mutation constitutes a pre-existing genetic function. (b) Some scholars claim the most fundamental conJict arises between dangerous and mutually threatening opponents. In studies of such conJicts, 80 percent of the time creatures from ants to mammals ac...

 "Scandals" - Animals Evolved from Cancer Cells

Panchin knows the idea of cancer-derived animals sounds far-fetched — so much so that, in the paper, he and his co-authors refer to them as Scandals (an acronym for “speciated by cancer development animals”). [...] According to Panchin’s three-step scenario, a Scandal would start off as a cancer, but not just any cancer. It would have to be transmissible, so that it wouldn’t die when its host did. Then the cancer would have to spread to other species, and then independently evolve...

 Seeing Organizations as Biological Systems

There’s a continuing struggle between complexity and robustness in both evolution and human design. A kind of survival imperative, whether in biology, engineering, or business requires that simple, fragile systems become more robust. But the mechanisms to increase robustness will in turn make the system considerably more complex. Furthermore, that additional complexity brings with it its own unanticipated failure modes, which are corrected over time with additional robust mechanisms, which ...

 Young Apes Resemble Human Children

Hartmann, in his work on the Anthropoid Apes (289, p. 301), quotes, approvingly, the words of Vogt: ‘When we consider the principles of the modern theory of evolution, as it is applied to the history of development, we are met by the important fact that in every respect the young ape stands nearer to the human child than the adult ape does to the adult man. The original differences between the young creatures of both types are much slighter than in their adult condition : this assertion, ma...

 The 800th Lifetime

It has been observed that if the last 50,000 years of man's existence were divided into lifetimes of approximately 62 years each, there have been 800 such lifetimes. Of the 800, fully 650 were spent in caves. Only during the last seventy lifetimes has it become possible to communicate effectively from one lifetime to another- as writing made it possible to do. Only during the last six lifetimes did masses of men ever see a printed word. Only during the last four has it been possible to measu...

 The Disruptive Nature of Homo sapien's Rapid Rise to Apex...

Genus Homo’s position in the food chain was, until quite recently, solidly in the middle. For millions of years, humans hunted smaller creatures and gathered what they could, all the while being hunted by larger predators. It was only 400,000 years ago that several species of man began to hunt large game on a regular basis, and only in the last 100,000 years – with the rise of Homo sapiens – that man jumped to the top of the food chain. That spectacular leap from the middle to the top ...

 Exchange is to cultural evolution as sex is to biological...

If culture consisted simply of learning habits from others, it would soon stagnate. For culture to turn cumulative, ideas needed to meet and mate. The ‘cross-fertilisation of ideas’ is a cliché, but one with unintentional fecundity. ‘To create is to recombine’ said the molecular biologist François Jacob. Imagine if the man who invented the railway and the man who invented the locomotive could never meet or speak to each other, even through third parties. Paper and the printing press...

 Falacy of Seeking Too Much Purpose in Evolutionary Adapta...

Darwin’s concept of evolution is centered on natural selection, or survival of the fittest [1]. Although Darwin did realize that organisms possess structures and even entire organs that might not have an extant function, as is the case of rudiments [2], on the whole, selectionist thinking has heavily dominated the biological literature ever since. In its extreme but not uncommon form, the selectionist, or adaptationist, paradigm perceives every trait as an adaptation. Under this view of bio...
