What proof do we have evolution taking place?

Evidence for evolution includes the fossil record, comparative anatomy, molecular biology, and observed instances of natural selection. These different lines of evidence all support the concept of biological evolution occurring over time.


What kind of change is taking place if white mold growing on a strawberry?

The white mold growing on the strawberry indicates a biotic change as it is caused by a living organism (fungus) that is breaking down and decomposing the strawberry. This can impact the shelf life and quality of the strawberry.


What is the degree of reduction for the chemical reaction taking place in this experiment?

The degree of reduction for a chemical reaction is the number of electrons gained by the atoms of a substance. It indicates how much the atoms have been reduced in terms of their oxidation state.


How can scientists tell if evolution is occurring?

Scientists can tell if evolution is occurring by observing changes in the genetic composition of a population over time, such as the frequency of certain traits or alleles. They also look for evidence of natural selection, genetic drift, or gene flow influencing the population. Comparing populations over different generations can help determine if evolutionary changes are taking place.


Can you observe evolution taking place?

Evolutionary changes generally occur over long periods of time and are typically not directly observable in individual organisms. However, evidence of evolution can be seen through changes in populations over successive generations as a result of natural selection, genetic drift, and other mechanisms. Scientists study these changes through observation of genetic variations and traits in populations.
