Mutations in an individuals germ line can be passed into progeny and if these mutations are beneficial then the allele frequency in the individuals population can change which is evolution. Over time and with many beneficial mutations against a favorable environment a population, or populations, most often geographically isolated, can change alleles so much that the two split populations can no longer interbreed and you have a new species; macro-evolution.

How do Darwin's findings point to micro evolution but not macroevolution?
Darwin's findings, such as natural selection, provide evidence for microevolution, which involves changes within a species over time. However, they do not offer direct evidence for macroevolution, which involves the formation of new species or higher taxa over long periods. Macroevolution typically requires additional mechanisms, like genetic mutations and genetic drift, to account for larger-scale changes.
What mechanisms account for speciation and macroevolution?
Speciation can occur through mechanisms like allopatric or sympatric isolation, where populations become reproductively isolated and diverge genetically over time. Macroevolution, which refers to larger-scale evolutionary patterns and processes, can be driven by factors like natural selection, genetic drift, and mutations that accumulate over millions of years, leading to the emergence of new species and diversity of life forms.
Which is not part of macroevolution?
Microevolution is not part of macroevolution. Microevolution involves small-scale changes within a species over a shorter period of time, while macroevolution involves larger scale changes that lead to the formation of new species over a longer period of time.
Are there complicated links between microevolution and macroevolution?
Microevolution is small evolutionary changes. Macroevolution is change above the specie level. Biologists debate if this process even exists. Some say they are fundamentally the same thing. It seems that macroevolution is the evolution of evolution. That sounds complicated.
Do monkeys that don't grow exist in the wild or are they a result of genetic mutations in captivity?
Monkeys that do not grow exist in the wild as a result of genetic mutations.

Is genetic drift an example of macroevolution?
No, genetic drift is an example of microevolution.
What are the causes of macroevolution?
Macroevolution is driven by several key factors, including genetic mutations, natural selection, genetic drift, and gene flow. These processes lead to significant changes in species over long periods, resulting in the emergence of new species and the diversity of life. Environmental changes and geographic isolation can also play crucial roles in shaping macroevolution by creating different selective pressures and promoting speciation. Overall, the interplay of these factors contributes to the complex patterns of evolution observed in the history of life on Earth.
Are all mutations generic?
Yes. All mutations of the genetic material are genetic.
What are the genetic mutations of dinosaurs?
HA! there are no genetic mutations! DINOSAURS ARE DINOSAURS! DINOSAURS ARE DINOSAURS! no mutants
What genetic material are called mutations?
Sudden genetic change in the DNA of an organism called mutations.
What are 5 things that can be considered support of theory of evolution?
1- Natural selections and mutations 2- Speciation and macroevolution 3- Fossil records 4- Strong connections between current species 5- Theory of common concent
Are genetic mutations always harmful to the individual?
Genetic mutations are not always harmful to the individual. A few may be beneficial.
What is a source of genetic variation that refers to a random error in the genetic code?
Mutations involve changes in the DNA code.
What mechanisms account for speciation and macroevolution?

Define a genetic mutation and state the types of genetic mutations?
A genetic mutation is a change in the DNA sequence that can affect an organism's traits. The types of genetic mutations include point mutations (substitution, insertion, deletion), frameshift mutations, and chromosomal mutations (deletion, duplication, inversion, translocation).
Which increases genetic variation?
Mutations
