What else can I help you with?
How are Dobzhansky and Mayr's ideas about the origin of species similar to Darwins?
They thought the evolution of new species is linked to environmental changes
What kind phenotypic changes are the of the result of evolution?
Changes that are genetic
How is theory of evolution of Darwin and Hugo deVries different?
Darwin considered evolution to be caused due to : 1)small changes/variations that occured 2)these variations were directed specifically towards adapting to the environment(directional) 3)evolution was a slow process De Vries believed that evolution occured by: 1)large changes that occured 2)these changes were mutations and were stochastic or random, not directional 3)evolution occured in fits and starts and was not a slow ongoing process
What are three examples for chemical change?
Burning, rusting, and production of gas are examples of chemical changes.
What aspect of DNA is considered the strongest supporting evidence for the theory of evolution?
It's mutability and it's heritability. It changes and these changes, in the germ line, are inherited by your progeny, The change in allele frequency over time in a population of organisms; evolution.
What is environmental evolution?
Environmental evolution refers to the changes in ecosystems and species over time in response to environmental pressures. This process includes adaptations and genetic changes that allow organisms to survive and reproduce in changing environments. Environmental evolution is a key component of the broader concept of evolution.
What are non examples of evolution?
Non-examples of evolution could include changes that are not driven by genetic variations or natural selection, such as changes due to environmental factors like climate or human intervention. For instance, the growth of a callus on the skin in response to friction is not an example of evolution, as it does not involve changes in the genetic makeup of an organism's offspring over generations.
Has evolution been observed?
Yes, evolution has been observed in numerous studies and experiments. Examples include the development of antibiotic resistance in bacteria, changes in beak size of Galapagos finches, and the coloration of peppered moths in response to environmental changes.
What are some examples of selective pressure?
Examples of selective pressure include predators preying on specific traits, competition for resources driving evolution towards efficiency, and environmental changes favoring certain adaptations over others.
How do most animals become extinct?
Through evolution, loss of natural habitat and environmental changes.
How is evolution and convergent evolution alike?
Evolution and convergent evolution both involve changes in organisms over time. However, convergent evolution specifically refers to the independent evolution of similar traits in unrelated species in response to similar environmental challenges.
What is the given name for genetic changes in living things over time?
The given name for genetic changes in living things over time is evolution. This process drives the diversity and adaptation of species in response to environmental conditions.
When a gene changes within a life span this process is called evolution?
Actually, the process of a gene changing within a lifespan is not called evolution. Evolution refers to changes in the genetic makeup of a population over many generations. Changes in a gene within an individual's lifespan may be due to mutations or environmental factors, but this does not necessarily lead to evolution.
What is the rate of evolution?
The rate of evolution can vary greatly depending on factors such as population size, mutation rate, natural selection pressure, and environmental changes. In some cases, evolution can occur rapidly, leading to significant changes in a short period of time, while in other cases, it can be slow and gradual over millions of years.
