Yes, both similarities and differences can be drawn out of any two objects. This would apply to any two animals, whether they were different or the same species.
yeah, they do
Of course - look at the many differences existing between the human race.
Generally, a molecular clock is used to describe the rate of molecular change over time that tells you when two species, or taxa, have diverged.
CompetitionCompetition among members of the same species is known as intraspecific competition, while competition between individuals of different species is known as interspecific competition.
Within a species, the animals breed together so that the similar characteristics are passed from parents to their offspring. This is why there is less variation within a species than between a species.
Comparative anatomy is the investigation and comparison of the structures of different animals. Scientists use comparative anatomy to study the difference between species and how they are alike in other ways. By comparing the similarities and differences between a number of species, scientists can then construct a picture of their evolutionary relationships.
The term used to describe the process for a new species developing from an existing species is "speciation." This process occurs when a population becomes reproductively isolated from the original species, leading to the accumulation of differences over time that eventually result in the formation of a distinct new species.
The differences between organisms is called Variation.
Genetic variations, which arise from mutations and recombination of genetic material during reproduction, are responsible for the differences between species and between individuals in the same population. These variations can lead to differences in physical traits, behaviors, and other characteristics among organisms. Additionally, environmental factors can influence the expression of these genetic differences, leading to further diversity within and between populations.
