Generally, the development of an organism is a modification of its ancestors' ontogenies according to macroevolution (Futuyma, 1998), and embryology provides testable confirmations and predictions about macroevolution (Gilbert, 1997).
Although he agrees with the power of natural selection to drive microevolution (evolution occurring within the boundaries of a species), his argument is that it is insufficient to account for macroevolution (evolution that jumps boundaries, leading to novel clades and species).
Soot is a strong, light-absorbing aerosol that caused global climate changes that triggered the mass extinction of dinosaurs, ammonites, and other animals, and led to the macroevolution of mammals and the appearance of humans.
The problem with macroevolution is that you can't set up an experiment to prove it.
Richard Goldschmidt (1878-1958) in 1940 has coined the terms of macroevolution, which means evolution from a long timespan (geological) perspective, andmicroevolution, which means evolution from a small timespan (a few generations) perspective with observable changes [1].
He did not produce said evidence, but instead used the red-herring claim (often used by intelligent design/creationists) that there is no evidence for macroevolution.
