Darwin goes on the web to confront critics: His complete works on-line
A website has been launched containing the largest collection of Darwin's writings ever assembled. This site contains every Darwin publication as well as many of his handwritten manuscripts. All told there are more than 50,000 searchable text pages and 40,000 images.

6.3.3 Photomultiplier tubes and detection circuitry

The visible photons are collected by an array of photomultiplier tubes behind the crystal. These convert each visible photon to an electron and then multiply the number of electrons sufficiently to give a voltage pulse. Because the number of visible photons is proportional to the energy of the incoming gamma ray, the height of the pulse depends on this energy. This gives a method of counting the numbers of gamma photons at different energies that reach the crystal.

Introduction
In this unit, we describe the theory of evolution by natural selection as proposed by Charles Darwin in his book, first published in 1859, On The Origin of Species by Means of Natural Selection, or The Preservation of Favoured Races in the Struggle for Life. We will look at natural selection as Darwin did, taking inheritance for granted, but ignoring the mechanisms underlying it.

2.1 Introduction
In the 18th and 19th century evolutionary biologists, including Darwin, emphasised the similarities between natural evolution and artificial ‘ improvement’ of livestock under domestication. They believed that studying domesticated animals and plants could illuminate the mechanisms of natural evolution.

The Fruits of the Genome for Society - February 17, 2010
Lunch 'n Learn presentation: The sequence of the human genome, the primary goal of the Human Genome Project, was achieved just a few years ago. Because our genomes are a string of 3 billion sequences of four chemical letters in the DNA polymer, the ability to obtain genomic sequences depended on revolutionary progress not just in DNA chemistry but also on the equally revolutionary advances in speed, capacity and versatility of digital computers. By far the most prominent result of the determinat

1.5.3 Summary of Section 1.5

  1. Some annual plants and insects can spend the winter at juvenile stages, such as seed, egg, larva or pupa. Butterflies in Britain display a variety of juvenile overwintering strategies.

  2. Migration often results in high mortality, but completion of the journey results in higher breeding success, due to increased availability of food and fewer competitors.

  3. Birds increase their body mass, sometimes by up to 50%, prior to migration. T
