Dating of rocks fossils and geologic events answer
Believing in beneficial mutations is like believing a short-circuit in the motherboard of your computer could improve its performance.To make any lasting change, a beneficial mutation would have to spread ("sweep") through a population and stay (become "fixed").A human generation takes about 20 years from birth to parenthood.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.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.
They exist in just about any environment: hot, cold, dry, wet, high pressure, low pressure, small groups, large colonies, isolated, much food, little food, much oxygen, no oxygen, in toxic chemicals, etc.
They said there was a "paucity of classic sweeps revealed by our findings". In this case the fruit flies weighed less, lived shorter lives, and were less resistant to starvation. Except for number 11, the changes found in over 60,000 generations of bacteria were due to the disruption, degradation, or loss of genetic information.
Sweeps "were too infrequent within the past 250,000 years to have had discernible effects on genomic diversity." "Classic sweeps were not a dominant mode of human adaptation over the past 250,000 years." --Hernandez, Ryan D., Joanna L. Cord Melton, Adam Auton, Gilean Mc Vean, 1000 Genomes Project, Guy Sella, Molly Przeworski. Classic Selective Sweeps Were Rare in Recent Human Evolution. There were many mutations, but none caught on, and the experiment ran into the . The ability to use citrate in the presence of oxygen, trumpeted by evolutionists as a big deal, was the result of previously existing information being rearranged, not the origin of new information.
The types of bird beaks, the colors of moths, leg sizes, etc. Each type and length of beak a finch can have is already in the gene pool and adaptive mechanisms of finches.
Creationists have always agreed that there is variation within species.

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.
