This chapter describes the early conditions on the earth. Methods for the estimation of the age of the whole Earth are based on the content of radiogenic lead in whole lead. Whatever the history of the atmospher
This collection highlights the different opinions on how to investigate the early formation of genetic material, honours the difficulties of early Earth research, and showcases some Nature Communications papers investigating the origin of life.

如果我们让环境条件决定人类environmental conditions to set the tempo(节奏) of human life? We're生活的节奏会怎么样?我们越来越意识到,我们不能仅increasingly aware of the fact that we can't control Earth systems with靠工程学来控制地球系统,engineering alone, and realizing that we need to moderate(...
While the actual origin of this anion within this carbonate rock is not clear, a possible source is from schreibersite corroding in water on the early Earth. Given the rather facile route to forming nucleotides from schreibersite under mild conditions (Gull et al., 2015), as well as other ...
