There is much misinformation about these two words, and yet, understanding them is perhaps the crucial prerequisite for understanding the creation/evolution issue.

Macroevolution generally refers to evolution above the species level so instead of focusing on an individual beetle species, a macroevolutionary lens might require that we zoom out on the tree of life, to assess the diversity of the entire beetle clade and its position on the tree macroevolution.

An ongoing debate in evolution is whether there is a distinction between macroevolution and microevolution, and if so, how to define that difference since the advent of molecular biology, with its insight into the molecular details of mutation, there has been a surge of thought that there is no fundamental distinction: evolution is evolution.

Macroevolution starts with the formation of new species the “wishy-washy” interpretation defines macroevolution as “evolution on the large scale”,. Micro-evolution is technically defined as evolution within a species, anything up to speciation without actual speciation macro-evolution is all evolution starting with speciation it is important to note that these terms do not refer to different processes: they describe the same process.
