1.Five page summary of Darwin’s ideas, written by Darwin for this occasion
2. Copy of Darwin’s letter to Asa Gray from 1857 to show he had not stolen Wallace’s ideas
3. Wallace’s paper, “On the Tendency of varieties to Depart Indefinitely from the Original Type”, 12 pages -
written by Darwin in 15 months during period of bad health. A lot of the book is devoted to artificial and natural selection, and the rest showed how common descent explains morphological similarities in systematic groupings, embryological similarities, rudimentary and vestigial organs, the geographic distribution of organisms, and fossil sequences in the stratigraphical column.
-
English biologist and Apostle; was a lifelong defender of Mendel's approach to the study of heredity.

German physician

Theodor Heinrich Boveri was a German zoologist, comparative anatomist and co-founder of modern cytology. Evidence that chromosomes contain hereditary factors dates from the work of Theodor Boveri in the 1880’s. He proposed that continuity of chromosomes from cell generation to cell generation, and their individuality, in contrast to Weismann’s speculations about chromosomes as passive to gene bins.
Also thought that cancer could start from one chromosome damage -
who had been a student of Karl Nageli’s in the 1880’s.
Encouraged Mendel to study Hawkweeds
Correns studied paired traits in peas (Mendel’s plant) and in maize. On April 21, 1900, he read de Vries paper, which did not credit Mendel. Because Corren disliked de Vries, he promoted Mendel’s priority and forced de Vries to mention Mendel in a later paper. -
Mid-1860's; establishment of the life to life principle Biogenesis by Louis Paster - although the idea had been around long before Pasteur.

Elucidated the structure of nucleotides and the difference between DNA and RNAl propose the tetranucleotide model of DNA
-
Meiosis is reductional division of the chromosomes, and is a necessary part of all sexual life cycles
-
Austrian agronomist who developed several new disease-resistant crops, including wheat-rye and oat hybrids.He bred peas. Using yellow/green cotyledons and round/wrinkled seeds (two of the pairs of traits Mendel had studied) and derived the same 3:1 F2 ratio. He also did the same backcrosses as Mendel had done and got the same results. He liked Mendel.
-
Oscar Hertwig (1876): in sea urchin, fertilization involves the penetration of an egg by a sperm cell. After the fusion of the gametes, the fertilized egg is one cell. After the fusion of the gametes, the fertilized egg is one cell with two nuclei, one from each gamete. The nuclei fuse, and the new nucleus divides when the fertilized egg divides.

de Vries concluded that the hereditary units were ‘intracellular pangenes’. Probably on the chromosomes.

it was of great interst to many geneticists and social commentators. GROSS

-
Walter Sutton (1903) observed that chromosomes in meiosis behave in the same way that Mendel’s hereditary determinants do. But there must be more genes than chromosomes
And if genes are on chromosomes, some genes should segregate together and wind up in the same sex cells - something Mendel and the Medelists had never observed. -

It demonstrated that the principles of the new genetics were sufficient to account for Darwinian evolution and showed that selection need not be intense to be important; also enlarged the set of causes of evolution, and argued that there was no barrier between microevolution and macroevolution
