Video: How America built UFOs
This video is about military secrecy. We study a documentary from 2011 when a lot of Area 51 information was declassified and when some people, including a high level CIA official were allowed to speak.I discuss my time when I was young when I was in the South African Navy and I handled Secret and Top Secret files and how these things work in real life.
Invasive species: Genes Are Destroyed With Admixture/Racial Mixing
Extinction by hybridization:
Nonindigenous species can bring about a form of extinction of native flora and fauna by hybridization and introgression either through purposeful introduction by humans or through habitat modification, bringing previously isolated species into contact. These phenomena can be especially problematic for rare species coming into contact with more abundant ones. Increased use of molecular techniques focuses attention on the extent of this underappreciated problem that is not always apparent from morphological observations alone. Some degree of gene flow is a normal, evolutionarily constructive process, and all constellations of genes and genotypes cannot be preserved. However, hybridization with or without introgression may, nevertheless, threaten a rare species’ existence.

USA: Black man stabs White woman and has sex with her as she dies...
I was a big fan of the show Medical Detectives. This story really got to me. And this Black man was not even executed.
