Abstract
... The Earth accreted approximately 4600 million years ago, but no rocks older than 4000 million years have been found, leaving the history of the first 600 million years missing. The oldest evidence for life can be traced back to between 3800 and 3500 million years and is based on chemical signatures, ...

Triclocarban
Triclocarban is an antibacterial agent common in personal care products like soaps and lotions as well as in the medical field, for which it was originally developed. Studies on its antibacterial qualities and mechanisms are growing. Research suggests that it is similar in its mechanism to triclosan and is effective in fighting infections by targeting the growth of bacteria such as Staphylococcus aureus. Additional research seeks to understand its potential for causing antibacterial resistance and its effects on organismal and environmental health.
