Humans have the remarkable ability to inhabit high altitudes where living conditions are especially harsh and challenging.

There are two types of nucleic acids (genetic molecules): DNA and RNA. DNA (deoxyribonucleic acid) is a large linear molecule designed to store genetic information in all cells. RNA (ribonucleic acid) serves as a blueprint for proteins and occurs in three forms: transfer-RNA, ribosomal RNA, and messenger-RNA.

An extensive series of South American Ice Age artwork may be of interest to biblical creationists.

Creationists have long speculated about the earth’s environment prior to the global Flood—conditions which may have contributed to the long human life spans recorded in the Biblical record of Genesis.

Her team’s recent discovery sets the stage for some answers.
