yes
Individuals that can interbreed and produce fertile offspring belong to the same species. This is a key criterion for defining a species and characterizes the gene flow between populations within the same species.
A population is a group of the same species that can interbreed and produce offspring for at least three generations.
No, the process of speciation occurs over many generations through evolutionary changes in a population. It is not a sudden event resulting from the mating of two individuals from different species. Speciation involves gradual divergence in traits and genetic makeup that eventually lead to the formation of a new species.
The process by which organisms produce offspring to perpetuate their species is called reproduction. It involves the fusion of gametes (sperm and egg) in sexual reproduction or the division of a single organism to create new individuals in asexual reproduction. Reproduction ensures the continuation of the species and passes genetic information to the next generation.
A species evolves over time through the process of natural selection acting on individuals within a population. Individuals themselves do not evolve, as evolution refers to changes in the genetic composition of a population over generations.

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.
All individuals of the same species have the same basic DNA and genetic code.
The gradual change in a species through adaptations over time is known as evolution. This process occurs through natural selection, where individuals with advantageous traits are more likely to survive and reproduce, passing on these traits to future generations. Over many generations, these small changes can accumulate, leading to the emergence of new species.
The mechanism that has been proven to show species change over time is natural selection, as proposed by Charles Darwin. This process involves the differential survival and reproduction of individuals with advantageous traits leading to changes in populations over generations.
Yes, some individuals of a population or species may be better suited to their environment due to genetic variations that give them certain advantages, such as increased fitness or adaptability. This can give them a higher chance of surviving and reproducing, passing on these beneficial traits to future generations. This process is known as natural selection.

Darwin believed that life on Earth has evolved over time through a process of natural selection, where individuals with traits better suited to their environment are more likely to survive and reproduce. This process leads to the gradual change of species over generations.
Members of a species are individuals that share common characteristics and can interbreed to produce fertile offspring. They are genetically similar but can exhibit variations due to factors like age, sex, and environment. The collective group of individuals within a species contributes to its overall diversity and survival.
