Whenever variation is pushed to extremes by selective breeding (to get the most milk from cows, sugar from beets, bristles on fruit flies, or any other characteristic), the line becomes sterile and dies out.
And as one characteristic increases, others diminish.
They say it took tens of thousands of generations to form man from a common ancestor with the ape, from populations of only hundreds or thousands. A new generation of bacteria grows in as short as 12 minutes or up to 24 hours or more, depending on the type of bacteria and the environment, but typically 20 minutes to a few hours.
There are more bacteria in the world than there are grains of sand on all of the beaches of the world (and many grains of sand are covered with bacteria).
The top problems with evolution explained using scientific evidence against evolution.
We tie a hammer to the wagging tail of a dog and let him wander about the work site for as long as you please, even millions of years.
"Despite decades of sustained selection in relatively small, sexually reproducing laboratory populations, selection did not lead to the fixation of newly arising unconditionally advantageous alleles." "The probability of fixation in wild populations should be even lower than its likelihood in these experiments." --Burke, Molly K., Joseph P. Most long-term evolution experiments thus far have been performed in bacteria or haploid yeast populations, where, in most environments, there exist a number of loss-of-function mutations that provide a selective advantage." "For instance, sterility in yeast provides a selective advantage by eliminating unnecessary gene expression." "The emergence of the Cit phenotype is the exception in experimental evolution, where most evolved mutations affect independent genes and biological pathways, driven largely by large-target loss-of-function mutations."This candid admission is from the evolutionist journal Nature: "Darwin anticipated that microevolution would be a process of continuous and gradual change.
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.
All known mutations in animal and plant germ cells are neutral, harmful, or fatal. They believe that millions of beneficial mutations built every type of creature that ever existed.
Believing in beneficial mutations is like believing a short-circuit in the motherboard of your computer could improve its performance.
