How well do you understand the dynamics and consequences if insular evolution and extinction?
This is a serious, in-depth natural sciences book that (keeping in mind that ecology is a multifarious science) the predominate thrust of is ecological insularity and its consequences. For me, it pulled together and connected the dots of much I've previously learned piecemeal, and added to my understanding. The extensive detail of the book may be daunting to some, but is very informative and sobering if one reads carefully and strives to comprehend the concepts. It is not a book for those simply interested in entertainment, but it is an exceptional book for those with objective, inquiring minds if read in whole.
Herein are the What, When, Where, and Why of evolution and extinction relative to population viability that we are developing an understanding of, as evidenced in insular (i.e. restricted, whether an island or mainland habitat fragment) species. The author does try to elucidate important concepts with layman examples (e.g. mismatched socks), and there is a glossary, but there are other general terms the reader might want a dictionary close by for (e.g. words like nomothetic and idiographic). In addition, the curious reader desiring to picture unfamiliar life forms mentioned might have a wildlife field guide at hand, or use Wikipedia.
Lightening the scientific thrust of the writing, there are bits of personal reflections and travelogs.
The book also spans how we have arrived at our current understanding, with a bit of satire. Rightly so to my mind, befitting humankind's self-aggrandizing intellect, encompassing contradictory, absurd explanations. Possibly the most recognizable of these being the irreconcilability of Noah's ark with biological reality. Where there are more sensible differences in scientific theory, the author is even handed.
“. . . evolution is best understood with reference to extinction, and vice versa. In particular, the evolution of strange species on islands is a process that, once illuminated, casts light onto its dark double, which is the ultimate subject of this book: the extinction of species in a world that has been hacked into pieces.”
“. . . species extinction is central to the question of how Homo sapiens affects its own world” and to our own threatened existence. Odds are that such as rats and coyotes will fare better than humans in the environmental changes we are ignorantly creating in our insatiable greed. One reason that stands out is the habitat fragmentation caused by our infrastructure (note the relevance with insular species dynamics). We have proliferated beyond ecological balance, and with our plows, livestock, axes, poisons, industry, self-serving religious beliefs, and no more intelligence in good part than other life forms have brought about the ongoing sixth great extinction. Much as we are prone to ignore inconvenient problems, we are not exempt from such.
This isn't only about non-human evolution and extinctions, but also how our proclivities have affected fellow humans. One section about Tasmanian Aborigines, in practice corresponds to the settling (read colonizing) of North America, differing only in population size and extent of consequences. Trying to persuade natives to accept 'the blessings of Christian civilization' [or any other cultural dogma] by any means is among the subjective hypocritical tenets that are hastening our diminishment. The author aptly terms the settlers so-called benevolent interaction with the Tasmanian Aborigines as “in the truest tradition of Orwellian doublespeak.” As in North America this "serving mainly to anesthetize the collective conscience of the conquerors.”
Awareness of our most serious problems, or developing such through reading and understanding, is essential to our and our children's futures. There may still be time to mitigate the consequences, but the only hope in time is if a critical mass of humans acknowledge and confront our destructive proclivities sufficiently to bring about positive change. As things are, we are presenting the short end of the stick to our children.
