How do genomes of species change?
Genomes can change through mutations, which are alterations in the DNA sequence. These mutations can arise randomly or be induced by external factors like radiation or chemicals. Over time, these changes can accumulate and drive evolution by providing genetic variation for natural selection to act on.
How can genetic mutations support macro-evolution?
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 does the mutations affect a species?
mutation is the ability to change in a species mutation help s the species to get better equipped with the environment .It is nothing but evolution for example mutation in the animals such monkeys paved the way for the humans to grow
What are the various kinds of mutations?
Mutations differ and change according to many factors: 1- Site of occurrence: -Genetic mutations -Chromosomal mutations 2- The inheritance: -Somatic mutations -Gamete mutations 3- The origin: -Spontaneous (natural) mutations -Induced mutations 4- The harmful OR useful effects: -Undesirable mutations -Desirable mutations
What factors influence how species evolve?
Factors that influence how species evolve include natural selection, genetic drift, gene flow, and mutations. These processes can lead to changes in the gene pool of a population over time, resulting in the evolution of new traits and eventually the formation of new species. Environmental factors, such as climate change and competition for resources, also play a significant role in shaping the direction of evolution.
Explain how a species can change over time?
Through mutations in DNA. If a mutation is beneficial and helps the organism survive it is passed on to the next generation which leads to the evolution of a species causing it to change.
How could multicellularity evolve?
Multi-cellularity evolved from mutations. This is how everything evolved throughout history. Random mutations that prove to be advantageous, and allow a species to continue to reproduce.
Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.
Why are mutations called agents of change?
Mutations are called agents of change because they introduce new genetic variations into an organism's DNA, leading to different traits or characteristics. These changes can result in evolution and adaptation to environmental pressures, making mutations essential for genetic diversity and the survival of species.

Why do mutations that occur in the skin or nervous system tend to have little effect on the evolution of a species?
Most mutations that occur have a neutral effect, or none at all, so they would not affect evolution. Organisms with mutations that cause detrimental impact typically will not survive; therefore, they will not reproduce, and the mutation will not be passed on, so the species will not be affected overall. Beneficial mutations are typically the only mutations that will affect an organism's posterity and the evolution of its species, but good mutations are very rare. This is why most mutations have little effect on the evolution of a species.

Can mutations increase the variations in a species' traits?
Yes
Did linnaeus believe species could change?
Linnaeus did not believe that species could change over time. He proposed the concept of fixed species, where each species had a distinct and unchanging form. This idea was influential in shaping early biological classification systems.
What can change in a gene do to a cell?
mutations
What is the importantce of mutations in producing genetic changes in a species?
Mutations are essential for generating genetic diversity within a species, which is crucial for adaptation to changing environments. They can lead to new traits that provide a selective advantage, allowing individuals with advantageous mutations to survive and reproduce, ultimately driving evolution. Without mutations, a species would lack the genetic variability needed to evolve and thrive in a dynamic world.
