J. G. M. "Hans" Thewissen.
The Walking Whales: from land to water in eight million years.
University of California Press. 2014
Hans Thewissen, a leading researcher in the field of whale paleontology and anatomy,
gives a sweeping first-person account of the discoveries that brought to light
the early fossil record of whales.
As evidenced in the record, whales evolved from herbivorous forest-dwelling ancestors
that resembled tiny deer to carnivorous monsters stalking lakes and rivers
and to serpentlike denizens of the coast.
Thewissen reports on his discoveries in the wilds of India and Pakistan, weaving a narrative that reveals the day-to-day adventures of fossil collection, enriching it with local flavors from South Asian culture and society. The reader senses the excitement of the digs as well as the rigors faced by scientific researchers, for whom each new insight gives rise to even more questions, and for whom at times the logistics of just staying alive may trump all science.
