From Darwin's time to the present, paleontologists have hoped to find the ancestors and transitional intermediates and trace the course
of macroevolution.
First, note that the «holistic» approach
of macroevolution implicitly incorporates the geologic time scales within the fossil record, allowing for comparison and contrast of the relatively minor and major morphological divergence of various forms (i.e. morphometric cladistics).
There is little or no empirical evidence supporting Darwin's claim
of macroevolution yet on «faith» someday we will prove it.
Not exact matches
So your entire basis
of why
macroevolution can not be valid is to compare it to an inatimate object being able to put itself together?
The term
macroevolution, by contrast, refers to the origin
of new species and divisions
of the taxonomic hierarchy above the species level, and also to the origin
of complex adaptations, such as the vertebrate eye.
Gould states that «the fossil record with its abrupt transitions offers no support for gradual change,» and then proposed that «
macroevolution proceeds by the rare success
of these hopeful monsters, not by continuous small changes within populations.»
You only have to look at your dog to see the benefits and proof
of «
macroevolution».
If we find an example
of irreducible complexity in nature,
macroevolution (Darwin's theory) is disproved.
You ignorant nutters have to believe in a super duper double top secret magical hyper
macroevolution to account for all these species
of beetle!
I understand that creationists who can no longer deny the evidence
of evolution, because we can observe it happening in bacteria evolving resistance to antibiotics, insects evolving resistance to pesticides, etc., now suggest that «microevolution» can occur, but «
macroevolution» can't.
If classical Darwinism isn't the explanation for
macroevolution, however, there is only speculation as to what sort
of alternative mechanisms might have been responsible.
Some experts do not believe that major changes and the appearance
of new forms (i.e.,
macroevolution) can be explained as the products
of an accumulation
of tiny mutations through natural selection
of individual organisms (microevolution).
He said: «The Darwinian mechanism that's used to explain all evolutionary change will be relegated, I believe, to being just one
of several mechanisms — maybe not even the most important when it comes to understanding
macroevolution, the evolution
of major transitions in body type.»
Michael Behe (in The Edge
of Evolution) points out that there is abundant evidence for «microevolution» (smaller population change), but there is a boundary at which the evidence for microevolution stops and evidence for
macroevolution either doesn't exist, or any clues that do exist are beset with problems so serious that explanatory attempts boil down to «just - so - stories.»
This leaves
macroevolution sitting atop a boundary (or wall) with an outlook no better that that
of Humpty Dumpty.
In addition to vestigial molecular fossils, we can point to any number
of anatomical vestigial traits supporting
macroevolution, e.g. the recurrent laryngeal nerve, the appendix, male nip - ples, arrector pili, etc, etc..
At last, we would have a truly experimental way
of studying
macroevolution, the kind
of changes that lead to the creation
of new species.
Are these the cumulative outcome
of the same processes that drive microevolution, or does
macroevolution have its own distinct processes and patterns?
If
macroevolution really is an extrapolation
of natural selection and adaptation, we would expect to see environmental change driving evolutionary change.
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.
Biology textbooks define the difference between micro - and
macroevolution as a matter
of degree.
