[Recommendation 10/2009]
Anyone, having followed our recent series here (even in a haphazard way), might have noticed we've repeatedly referred for this book. Not surprising, since we've also recently a lot focused on topics of animal prehistories and distant evolutionary pasts. This actually has been, perhaps from two reasons:
First is simply because of Mammoths, Sabertooths and Hominids is very good introduction to those things, concerning (mostly) those millions and millions of years before species named sapiens(es) ever walked on Earth. And like the subtitle says, book covers mammalian evolution from Paleocene period (ca 65-55 Million years ago) to the most recent epoch preceding current times, the Pleistocene (about 1.8 Ma to 10000 BC) - actually the subtitle more correctly gives impression from books contents than the well-known species mentioned in main title. The book takes in closer examination vast number of those foregone creatures, most of them from more distant origins.
The second mentioned reason is equally meaningful (for myself). It is from the reason(/must confess that) in schools having skipped the course about the mentioned subject. So, therefore I've found myself desperately in need to fill some 'blackouts' on my knowledge from this field of study. And, as it being so I never finished the course, I'm often in these text borrowing a bit from more peculiar sources that are loosely connected characters in the archeologic history and past, early architect-archeologist's or similar innovators of the study – fx some famous ones like Frederick Bligh Bond (1864-1945) and Sarah Winchester (1839-1922). But returning to the recommendation here, this book is only presented here as an example from more modern (/more recent) researches and readings. (And, I'll also have to add that likely our aim to focus on female authors in these subsequent posts will now have to be delayed for a little further.)
The book may be in use as course-book or additional reading at universities, and as such it's not perhaps the first text to start from, if looking to read from the 'evolutionary roads' preceding the present environments and ecology. But it's not too complicated or difficult if having some basic knowledge from the earlier prehistoric periods. And they mention in the forewords its main purposes being fx offering a presentation from mammalian evolution (in Europe) for wide range of readers; from geologists to students, scholars, etc. As it focuses on study of the fossil fauna, things are presented rather chronologically, an aspect that also makes it somewhat easier to follow, if sometimes little boresome from the unprofessional readers view-point.
But, like said, it is still very recommendable as presenting a carefully structured picture from the prehistoric animal evolution (mammalians especially, of course). In overall also fx what is known from the climates in during past geologic periods. Perhaps the more recent techniques/molecular studies isn't that much covered in the book, but as I kind of remember having read the DNA discriminated from fossilized bone giving reliable clues only somewhat a million years to the past, this is only logical. Also the classification of those ancient species, especially nowadays foregone genera, isn't at all clear in every case, and the information of course sometimes changes in times with further studies. But I guess this must present quite much the most recent knowledge and foundings (mainly) on the basis of these 'traditional' research methods.
The larger parts are devoted to the earlier (faunal) periods in the prehistory - Paleocene, Eocene, Oligocene, Miocene, Pliocene. Also, the reader finds major part of pages dedicated for the more distant periods than the ones closer to our times. This is also only logical, and quite as well underlines how recent actually is the age of man - and - how much more further reaches the history of most other creatures of the Earth (and the book only concerns youngest of animal orders, the mammals).
Not even trying to describe any of those periods discussed in the book with more detail, we're only mentioning here some things that were most of interest to us. Of course described are the evolutionary paths in behind of the current existing species, like the origins/lineages of Perissodactyls, Artiodactyls, various carnivorous mammal genera, and, as well fx the Lagomorphs (rabbits/hares) and Rodents. As well, one also learns quite an amount of information from many lineages that once existed, but now are known only from fossil remains: fx Multituberculates, Machairodonts, Chalicotheres, Creodonts – An interested reader can of course read a quite deal from them also in the net, though not explained as much with detail and throrough way. Going the further for the past, the less clear/sometimes differing in views are also these classifications concerning the (groups of) species, like in the case of the latter mentioned (Creodonts), as is described here (the post also has pic from painting that funnily 'jokes' on this question). Of course, one has first to be somewhat interested from all those foregone times to enjoy the book largely focusing on explaining the changes of individual species and mammalian families during the path of some 60 million years evolutionary diversification.
But, then in the book are also mentioned some interesting 'zoo geographic problems' and geologic effects that has been able to show having happened in the past and had their affluence on all these things. I only mention here some briefly since they aroused interest in myself : The presence of Eurotamandua in Eocene faunas (of Europe), supposedly resulting from the existence of Iberian-African corridor in the Mid-Eocene ; the sudden appearance (from out of nowhere) of the early Chiroptera (bats), in the early Eocene ; the “Gomphoterian land-bridge” (early Miocene). And, other things that one is most delighted to read from, if having some interest on these distant times. Exciting especially since all of it predates so far in the past, and yet can still be reasoned and studied in our times.
