The beak of the finch

Weiner follows the career of two biologists, Peter and Rosemary Grantwho have spent twenty years proving that Charles Darwin did not know the full strength of his theory of evolution.

Evolution -- Darwin's Finches - 1

How is this different from normal scientific process? What is the role of experimentation for proving and supporting theories?

Why did they focus on Galapagos finch species? How were beak sizes and shapes used as critical determinants of divergences and speciation? What role did weather and climate shifts play in their observations of selection?

Similarly, what were the accompanying changes in vegetation effect selection? How did the interplay of bees and nectar drinking finches demonstrate that different species can exert selective pressure on each other, not only intra-species effects? What are the characteristics of a species?

The Beak of the Finch tells the story of two Princeton University scientists—evolutionary biologists—engaged in an extraordinary investigation. They are watching, and recording, evolution as it is occurring—now—among the very species of Galápagos finches that inspired Darwin’s early musings on the origin of species. The Beak of the Finch Outcomes Images with connections Competition Competition among members of a species is a key part of natural selection. It's well covered in this book, from competition for food sources to competition for mates. The Beak of the Finch is an elegantly written and compelling masterpiece of theory and explication in the tradition of Stephen Jay Gould.

What are the differences in natural selection versus sexual selection and how do they combine to produce diversity and speciation? How did the fruit fly studies contribute to understanding selection and formation of species?

In the 20 years since this book was published, genetic sequencing of DNA has become a very powerful tool for biologists, enabled by complete DNA analysis of individual organisms.

How might this type of analysis affect our understanding of natural selection and the studies conducted in this book? The book includes numerous, diverse examples separate from the finches of the Galapagos of selection pressures leading to divergence including for bacteria antiobiotic resistanceinsects pesticide resistancemoths color changeelephants loss of tusks.

How do these phenomena extend and mostly reinforce the observations of the Grants? The subject of evolution is still difficult and controversial for many people.

Why do people for the most part appear to understand and accept the observations of selective pressure and divergence, such as those described in this book, yet reject evolution?Darwin's finches. All those clever birds adapted to fill niches that might normally be filled by other birds.

There was quite a lot of detail about studies into the Galapagos finches, which was great! The finches & how quickly they are evolving is super interesting/5.

Working with others in your team, examine the cards of the Galapagos finches and arrange the species into groups based on their characteristics. Grouping species according to shared characteristics can provide clues to how they have evolved.

On the lab table, display the cards according to the.
