<span><span>The blood cells containing hemoglobin, that transports oxygen (O2) to the body tissues of vertebrates, are called red blood cells.</span> Red blood cells (RBCs), are also referred to as red cells, red blood corpuscles, haematids, erythroid cells or erythrocytes<span>, (from Greek erythros for "red" and kytos for "hollow vessel"..RBCs take up oxygen in the lungs and release it into tissues while squeezing through the body's capillaries.</span></span>

Body parts of unrelated organisms that serve the same function are examples of convergent evolution.
<span>Convergent evolution is the phenomenon when the different species independently create similar features. Those features can be structures that have similar form or function. This happens because organisms have been adapted to similar environments or ecological niches.</span>
Big growth is
<span>macroevolution as small growth is to microevolution</span>
The type of competition that exist between the two species is INTERSPECIFIC COMPETITION.
There are basically two types of competition in any given ecosystem, these are intraspecific and interspecific competition. Intraspecific competition occurs among organisms of the same species while interspecific competition occurs among organisms of different species.<span />
