> NIH Deputy Director and former Acting NIH Director, Dr. Lawrence Tabak, acknowledged that NIH funded gain-of-function research in Wuhan, China.

> Also, in 2018, just one year before the outbreak in a DARPA grant proposal, Wuhan Institute of Virology and its collaborators proposed to construct genetically modified SARS viruses having a furin cleavage site, a feature associated with increased viral growth and increased transmissibility. They proposed to insert the furin cleavage site at the spike gene S1/S2 border, and to construct the viruses by synthesizing six nucleic acid-building blocks, and assembling them using the reagent BsmB1.

> Fourth, in 2019, a novel SARS virus having a spike with extremely high binding affinity for human SARS receptors, a furin cleavage site inserted at the spike S1/S2 border, and a genome sequence with features enabling assembly from six synthetic nucleic acid building blocks using the reagent BsmB1--a virus having the exact features proposed into 2018 NIH and DARPA proposals--emerged on the doorstep of Wuhan Institute of Virology.

> Taken together, the presence of a spike having an extremely high affinity for human SARS receptors, the presence of a furin cleavage site inserted at the spike S1/S2 border, the genome sequence enabling assembly from six synthetic nucleic acid- building blocks using the reagent BsmB1, and the one-for-one match between these features and the features proposed in the 2018 NIH and DARPA proposals, make an extremely strong case--a smoking gun--for a research origin.
