Lamarck Develops hypothesis of of evolution by means of acquired characteristics
The hypothesis if an organism changes during life in order to adapt to its environment. Lamarck had this hypothesis. -
The Voyage of the HMS Beagle
It was a voyage that Darwin was in. the ship was the second survey expedition of HMS Beagle, and the captain was Robert FitzRoy . In this trip Darwin explored different lands he spent 3 years on land and 18 months at sea. -
The origin of Species by means of Natural Selection is published

Germ Theory of Disease says that diseases are caused by microorganisms. Their hosts can be animals, humans, or other living hosts and their growth ad reproduction within these hosts can cause a disease. -
Gregor Mendel publishes works on inheritence of traits in pea plants
Gregor Mendel discovered fundamental laws of inheritance through his work on pea plants -
Plasmodium Falciparum
Plasmodium falciparum is a unicellular protozoan parasite that cause malaria in humans. Its spread by female Anopheles which is a species of mosquito. -
Hardy and Weinberg Independently developed the hardy-weinberg
The Hardy-Weinberg equilibrium is the fundamental concept in population genetics (the study of genetics in a defined group). It is a mathematical equation describing the distribution and expression of alleles (forms of a gene) in a population, and it expresses the conditions under which allele frequencies are expected to change. -Biology Reference Read more: http://www.biologyreference.com/Gr-Hi/Hardy-Weinberg-Equilibrium.html#ixzz51NaBlfIP -
T.Hunt Morgan discovers sex-linkage
The phenotypic expression of an allele that is dependent on the gender of individual and directly tied to the sex chromosomes. -
Neils Bohr
In atomic physics, the Rutherford–Bohr model or Bohr model or Bohr diagram, introduced by Niels Bohr and Ernest Rutherford in 1913, depicts the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus. -
Frederick Griffith Describes the process of transformation
Griffith's experiment was an experiment done in 1928 by Frederick Griffith. It was one of the first experiments showing that bacteria can get DNA through a process called transformation. These bacteria infect mice. He used a type III-S (smooth) and type II-R (rough) strain. -
Avery, MacLeod and McCarty Determine that DNA is the molecule that carries the genetic code
The Avery–MacLeod–McCarty experiment was an experimental demonstration, reported in 1944 by Oswald Avery, Colin MacLeod, and Maclyn McCarty, that DNA is the substance that causes bacterial transformation, in an era when it had been widely believed that it was proteins that served the function of carrying genetic information (with the very word protein itself coined to indicate a belief that its function was primary). -Wikipedia -
Hershey- Chase experiments are published
They worked on the T2 which is a DNA virus which infects E Coli, which is also a bactriophage. -
Rosalind Franklin works with DNA and X-Ray crystallography and develops “Image 51”
Photograph 51 is the nickname given to an X-ray diffraction image of DNA taken by Raymond Gosling in May 1952. She was working as a PhD student under the supervision of Rosalind Franklin, at King's College London in Sir John Randall's group. It was critical evidence in identifying the structure of DNA. -
Meselson and Stahl work with DNA replication
The Meselson–Stahl experiment is an experiment by Matthew Meselson and Franklin Stahl in 1958 which supported Watson and Crick's hypothesis that DNA replication was semiconservative Meselson and Stahl proved that the semiconservative model of DNA replication was correct. -
Nirenberg cracks the genetic code
It is a sequence of three bases of DNA that codes for one of the twenty amino acids that serve as the building blocks of protein it was discovered by Marshall Nirenberg http://www.genomenewsnetwork.org/resources/timeline/1961_Nirenbe -
Watson and Crick propose the DNA structure
Francis and Crick both suggested that the molecule was made of two protein strands. They found that during cell division they separate into two strands, the double Helix model. Link: http://www.pbs.org/wgbh/aso/databank/entries/do53dn.html -
Endosymbiosis is described by Lynn Margulis
Margulis's first article on endosymbiosis was written. Margulis's theory is often referred to as the set: serial endosymbiotic theory. -
Apollo 11 lands on the moon
Apollo 11 was a lunar landing mission that was accomplished by Neil Armstrong and Buzz Aldrin, they are currently known as the first humans to take the first steps on a planetary body. -
The Sanger Technique
Sanger sequencing, also known as the chain termination method, is a technique for DNA sequencing based upon the selective incorporation of chain-terminating dideoxynucleotides (ddNTPs) by DNA polymerase during in vitro DNA replication. It was developed by Frederick Sanger and colleagues in 1977. -
Deep sea hydrothermal vents and associated life around them are discovered
In 1977, scientists exploring the Galápagos Rift along the mid-ocean ridge in the eastern Pacific noticed a series of temperature spikes in their data. The scientists had made a fascinating discovery—deep-sea hydrothermal vents. They also realized that an entirely unique ecosystem, including hundreds of new species, existed around the vents. -
Kary Mullis
In 1985 while working as a chemist at the Cetus Corporation, a biotechnology firm in Emeryville, California, Kary B. Mullis invented the Polymerase Chain Reaction (PCR) technique which allowed scientists to make millions of copies of a scarce sample of DNA. Kary Mullis invented the PCR technique in 1985 -
Louis Pasteur refutes spontaneous generation
Louis Pasteur set up two experiments to test whether sterile nutrient broth could spontaneously generate microbial life. Pasteur added nutrient broth to two flasks, bent the necks into an 'S' shape, and then boiled the broth to kill any existing microbes. -
CRISPr/CAS 9
CRISPR is a family of DNA sequences in bacteria. The sequences contain snippets of DNA from viruses that have attacked the bacterium. -
The Innocence Project Is Founded
it is a non-profit legal organization that was founded in 1992 by Barry Scheck and Peter Neufeld. The organization is committed to exonerating wrongly convicted people through the use of DNA testing and to reforming the criminal justice system to prevent future injustice. -
Dolly The sheep is cloned
Female domestic sheep and the first mammal cloned from an adult somatic cell, using the process of nuclear transfer. -
sahelanthropus tchadensis fossil discovered
Its an ape that lived between 7 and 6 million years ago in West-central Africa (Chad). It is the oldest known species in the human family tree. -
Human genome full sequence
Human genome is a set of nucleic acid sequences, concealed as DNA within 23 chromosome pairs in cell nuclei and in a small DNA molecule found within individual mitochondria. -
Spliceosomes were discovered and described
Spliceosomes are large and complex molecular machine found in the splicing speckles of the cell nucleus of the eukaryotic cells. They are assembled from snRNA and protein complexes. The process, described as splicing, is when the spliceosome removes introns from the transcribed pre-mRNA, which is a type of primary transcript.
