"But it really wasn't until three to four years later, when we had an opportunity in the lab to make very detailed observations, and comparisons with other fossil discoveries, that we realized she was a new species of human ancestor"

This quote by Donald Johanson sheds light on the painstaking and precise process of scientific discovery, particularly in the field of paleoanthropology. Johanson, a popular paleoanthropologist, is perhaps best known for his discovery of "Lucy", a 3.2-million-year-old Australopithecus afarensis skeleton, which offered extensive insights into human evolution.

In the quote, Johanson reflects on the journey from the preliminary discovery of fossilized remains to the ultimate recognition of their significance. He highlights that the procedure of recognizing a new species is neither immediate nor uncomplicated; rather, it includes years of extensive research and analysis. The expression "three to 4 years later" symbolizes the long-lasting commitment and persistence needed in scientific research. It recommends that preliminary suspicions or hypotheses often need considerable proof and improvement before they end up being accepted clinical understanding.

The mention of "detailed observations" underscores the value of extensive assessment in paleontology. The initial excitement of discovering a fossil is merely the start; the genuine work depends on the comprehensive analysis and comparison with recognized specimens. This involves comparing morphological functions, using innovative imaging techniques, and often even performing hereditary analyses if viable DNA can be drawn out.

"Comparisons with other fossil discoveries" highlights the collective and cumulative nature of scientific work. Discoveries seldom happen in isolation; rather, they base on the shoulders of previous findings. By comparing new findings with existing fossils, scientists can put them within the more comprehensive context of evolutionary history, distinguishing unique traits that might justify classifying them as a brand-new species.

Lastly, Johanson's awareness that "she was a brand-new species of human ancestor" represents a breakthrough minute that broadens our understanding of human origins. This part of the quote encapsulates the thrill of discovery and the extensive effect such findings have on our understanding of where we come from. Overall, the quote shows the commitment, collaboration, and complex process involved in uncovering mankind's deep past.
