Darwin and Wallace proposed _______ to explain the evolutionary process.
NATURAL SELECTION

MENDEL
Hereditary variations occur spontaneously from alterations in genes is called?
mutations.
Occurs when all individuals of a specie disappear and do not survive environmental changes
Extinction
It is the study of the history of life on Earth as based on fossils.
Paleontology
