Respuesta :
The foundation for biological evolution or descent through modification is the changes that occur within the DNA of species or organisms. These genomes change because they need to adapt and give birth to strong species that will survive through time. This is actually naturally occurring as suggested by Charles Darwin.
Change in physical structure is a type of change that exemplifies biological evolution in an organism.
What is biological evolution?
Biological evolution is the change in inherited traits in populations of organisms with the passage of time. Modification of traits occurs by gene mutation, genetic recombination or genetic drift.
So we can conclude that change in physical structure is a type of change that exemplifies biological evolution in an organism.
