evolution
Darwin's idea of "descent with modification" suggests that species evolve over time through the process of natural selection, where favorable traits are inherited by subsequent generations. Fossil evidence and the study of modern organisms indicate that genetic changes accumulate over time, leading to the diversity of life we see today. This concept underpins the theory of evolution, highlighting the connection between ancestral species and their modern descendants.

Reproduction is the process that allows a species to produce new generations of individuals. It involves the formation of offspring either sexually or asexually to ensure the continuation of the species. Reproduction is essential for the perpetuation of life and genetic diversity within a species.
A population is a group of the same species that can interbreed and produce offspring for at least three generations.
Populations undergo changes in gene frequencies through processes like natural selection, genetic drift, and gene flow, which contribute to the evolution of a species over many generations. This can lead to the emergence of new traits or the adaptation to changing environments within a population.
The theory of evolution by natural selection, proposed by Charles Darwin, explains the diversity of species developed through gradual processes over many generations. This theory suggests that individuals with favorable traits are more likely to survive and reproduce, passing on those traits to their offspring, leading to changes in species over time.

Gradual changes in species over time is known as evolution. This is a process where populations of organisms change over generations as a result of genetic variation, natural selection, and adaptations to their environment. Over time, these changes can lead to the formation of new species.
B. Many small changes can eventually make a species very different.
Most of said species die, if there is a favorable mutation existent in the population that characteristic will become more prevalent. If not the species will most likely go extinct.
Evolution of a species involves changes in inherited traits over generations, driven by factors like genetic mutations, natural selection, genetic drift, and gene flow. These changes can result in the development of new species from a common ancestor through processes like speciation.
aids in the dispersal of the species
Scientists can study how mutations cause changes over many generations by observing the genetic variations that accumulate in populations over time. By analyzing the frequency of mutations and their effects on traits, researchers can speculate on how these changes lead to evolutionary shifts in species.
Evolution. It refers to the process by which populations of organisms accumulate changes over successive generations, resulting in genetic variations that can lead to new species.
Sexual reproduction helps evolution because it allows for changes to take place over generations. Without any reproduction, no evolution would occur because the species only sees change over time and generations, it cannot be seen in one lifetime. Plus, without reproduction, the species will become extinct.
Nonliving factors such as climate change, natural disasters, and changes in water availability can alter a species' habitat and resources over several generations. These changes can influence factors like food availability, temperature, and shelter, leading to adaptations and evolutionary responses in species to survive in the new environmental conditions.
This concept relates to the theory of evolution by natural selection, which explains how minor changes in individuals over time can lead to the emergence of new species. These variations in a population can increase the chances of survival and reproduction for certain individuals, ultimately shaping the genetic makeup of future generations.
