• Genetics and Evolution

2
1663

• Robert Hooke (1635-1703) observed cell structure
  in a thin slice of cork.

3
1683

• Anton Van Leeuwenhoek (1632-1723) observed
  single-celled organisms through the microscope
  that he invented.

4
1838

• Matthais Schleiden (1804-1881) observed that
  plants are composed of cells.

5
1839

• Theodor Schwann (1810-1882) observed that animals
  are composed of cells.

6
1855

• Rudolf Virchow (1821-1902) proposed that new
  cells come from pre-existing cells.

7
1858

• Charles Darwin(1809-1882) and Alfred Russel
  Wallace (1823-1913) proposed an explanation for
  how evolution occurs.

8
1866

• Gregor Mendel (1822-1884) presented the results
  of his genetic research of inheritance of traits.

9
1903

• Walter Sutton (1877-1916) proposed that traits
  are inherited by offspring from parents through
  the chromosomes.

10
1953

• James Watson (1928-) and Francis Crick
  (1916-2004) discovered the structure of DNA.

11
1955

• Henry Bernard Kettlewell (1907-1979) conducted
  experiments to test natural selection among
  peppered moths.

12
1972

• Stephen Jay Gould (1941-2002) and Niles Eldredge
  (1943-2005) proposed the theory of punctuated
  equilibria to explain rapid evolution in short
  periods of time.

13
1976

• Lydia Villa-Komaroff (1947-) pioneered
  experiments in genetic engineering that lead to
  new ways of producing drugs such as insulin.

14
1996

• Ian Wilmut (1944-) responsible for cloning a
  sheep cell resulting in Dolly the lamb.
