While various religions cling to notions their unique gods formed the universe, science continues to unravel mysteries of how we came to be here. A new thing I read about is gene jumping. It is that some genes in the make up of living creatures such as ourselves did not come from parent to offspring but moved horizontally from creatures of separate species. One fourth of the genes of cud chewing animals, i.e. cows, are shared with and seemed to have come from reptiles.
The origin of some genes is not known. Neither is exactly how they ended up in other creatures. One idea is insects exacted blood from one species and left some in another.
The gene studied, “Bovb,” is thought to have jumped between species at least eleven times. When the new host species had its DNA changed by the new cell, it is thought the evolutionary path must surely have been altered.
Investigation has also found genes change over time. Thus, a gene that appears today in different species is often different from the same gene in species of more distant relatives.
Evolution often involves drawing family trees. When scientists draw plot the species who share Bovb the drawing is a complicated maze of horizontal relationships.
Parts of Christianity have vigorously argued against the field of evolution saying there are various questions which remain unanswered. Certainly not everything is known.
That evolution did not always have a continuous and straight path but rather fast changes periodically may be explained eventually.
