Lamarck develops Hypothesis of evolution
In 1801 the Theory of Incoherence of Acquired Characteristics was first presented by Lamarck. If an organism changed in order to adapt to a new environment, those changes will be passed on to its offspring. -
Spliceosomes
accomplices are huge RNP, complexes found in only eukayotic cells. The spliceosome removes introns from a transcribed mRNA, this process is called splicing. -
Louis Pasteur refutes spontaneous generation
An experimented created by Louis Pasteur in 1859, to test if sterile nutrient broth can generate life. He added nutrient broth to flasks, then bent the necks of the flasks and then boiled the broth to kill any existing microbes. If the broth in the flasks became cloudy, its a sign that it as microbial life -
The Origin of species by means of Natural Selection
A book written by Charles Darwin in 1858, that is considered to be the foundation of evolutionary biology. He talks about scientific theory, evolution, natural selection and the diversity of life. -
Gregor Mendel publishes works on inheritance of traits in pea plants
Gregor Mendel found the fundamental law of inheritance, though a series of experiments of pea plants. Mendel's Laws of are: Law of segregation, Law of independent assortment, and law of dominance. -
The Germ Theory of Disease
The germ theory that many diseases are caused by microorganisms. These microorganism invade the human body and cause diseases. These are called pathogens, and the disease they cause are called Infectious disease. -
Hardy and Weinberg independently develop the Hardy-Weinberg equation for determining allele frequencies in populations
The Hardy and Weinberg equilibrium is the study of genetics and a defined group. It is a mathematical equation describing the expression of alleles in a population. (alellel is expected to change). In this equation (p² + 2pq + q² = 1), p is defined as the frequency of the dominant allele and q as the frequency of the recessive allele for a trait controlled by a pair of alleles

Neils Bohr develops the Bohr model of atom structure
Neils Bor and Ernest Rutheford introduced The Bohr Model mentioned how atoms have a the similar structure as a solar system , but with attraction provided by electrostatic forces rather than gravity. -
Frederick Griffith describes the process of transformation
in 1928, Fedrick Griffith a bacteriologist, demostraded bacterial transformation, where bacteria changes its from and function. he showed that a strain could be transformed into a different strain.

Avery, MacLoed and McCarty determine that DNA is the molecule that carries the genetic code
An experiment tested by Oswald Avery, Colin MacLeod, and Maclyn McCarty that DNA(not proteins) is the substance that is responsible for bacterial transformation. -
Rosalind Franklin works with DNA and X-Ray crystallography and develops “Image 51”
Rosalind Franklin was a chemist that helped discovered some of the most crucial clues to dna structures. Franklin used an X-ray crystallography, when a molecule like dna is exosed to X rays, it gives diffraction patters that that give clear clues to the molecules structure. -
Hershey-Chase experiments
the Hershey-Chase experiments were a set of experiments that proved that DNA is in fact genetic material. These experiments were conducted by Alfred Hershey and Martha Chase in 1952. -
Watson and Crick propose the double helix model of DNA structure
James Watson and Francis Crick discovered the double helix structure of DNA. This discory lead with insights and genetic code and protein synthesis.It later helped to produce new and powerful scientific techniques. -
The Sanger Technique is developed
In 1977, Federick Sangers developed a technique for a rapid sequence of DNA, and this method i used to determine the order of bases in a strand of DNA. -
The Innocence Project is founded
Founded in 1992, The Innocence project is a mission to free the innocent people that are incarcerated and to begin a reform to bring justice for unfair imprisonment. -
Apollo 11 lands on the moon
Neil Armstrong, the first man to step foot on the moon. Apollo 11 ls was the first lunar mission to land successfully on the moon. -
Sahelanthropus tchadensis fossil discovered
One of the oldest known species in the human tree. This species lived approximately 6-7 billions years ago in the West central Africa. The first and only discovery of this fossil was in 2001. Cranial fossils were only found that showed a combination of ape like- human like resemblance, including small brain, elongated skulls and sloping faces. -
Human genome is fully sequenced

CRISPr/CAS 9 is identified and described
CRISPr/CAS 9 is a genome editing tool that is more efficient than any previous DNA editing techniques. "CRISPR-Cas9 is a unique technology that enables geneticists and medical researchers to edit parts of the genome? by removing, adding or altering sections of the DNA? sequence. "
