The Paleo-species of Homo neanderthalensis have been the subject of debate since their discovery in 1829. Even in the early beginnings, the scientific research concerning this early hominin species has been debated, and it was not until 1864 that the first Homo neanderthalensis was recognized as an early hominin fossil (citation). Fortunately, progress has been made into piecing back together the history of Homo neanderthalensis. However, there are still significant questions that remain unanswered; a broad example of one of those questions is what was the contributing factor to their extinction.
Fortunately, there has been a significant amount of research done which pertained to them not being able to adapt to the changing climate on the latter half of the Pleistocene or were out competed by anatomically modern humans either by technology and cultural adaptation or even interbreeding. These theories could potentially explain their extinction because each one explored a different aspect of Neanderthal life. L. Dalén et al. theorized low mDNA, or mitochondrial DNA, which is only passed down through the maternal lineage through generations, was caused by the climate change in the latter half of the Pleistocene, about 58 thousand years ago, which predated the arrival of anatomically modern humans. While another theory suggested that, slightly before the extinction of the Neanderthals globally, anatomically modern humans interbred with Neanderthals on
