دانلود کتاب Consider the Platypus: Evolution through Biology’s Most Baffling Beasts

Interested in the origins of the species?Consider the Platypususes pets such as dogs and cats as well as animal outliers like theaxolotl and naked mole rattowittily tackle mind-bending concepts about how evolution, biology, and genetics work.Consider the Platypusexplores the history and features of more than 50 animals to provide insight into our current understanding of evolution. Using Darwin's theory as a springboard, Maggie Ryan Sandford details scientists' initial understanding of the development of creatures and how that has expanded in the wake of genetic sequencing, including the:Peppered Moth, which changed color based on the amount of soot in the London air;California Two-Spotted Octopus, which has the amazing ability to alter its DNA/RNA not over generations but during its lifetime;miniscule tardigrade, which is so hearty it can withstand radiation, lack of water and oxygen, and temperatures as low as -328°F and as high 304 °F;and, of course, the platypus, which has so many disparate features, from a duck's bill to venomous spur to mammary patches, that scientists originally thought it was a hoax.Surprising, witty, and impeccably researched, Sandford describes each animal's significant features and how these have adapted to its environment, such as the zebra finch's beak shape, which was observed by Charles Darwin and is a cornerstone of his Theory of Evolution. With scientifically accurate but charming art by Rodica Prato,Consider the Platypusshowcases species as diverse as the sloth, honey bee, cow, brown kiwi, and lungfish, to name a few, to tackle intimidating concepts is a accessible way.
