Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment
<em>Two or more species share a unique physical feature,</em> for example, an unpredictable bone structure or a body plan, they may all have acquired this component from a typical predecessor.
Physical highlights shared because of developmental history (a typical progenitor) are said to be homologous.
<em>The front flippers of whales and the forelegs of four-legged vertebrates like canines and crocodiles are completely gotten from the equivalent tribal tetrapod structure.</em>
True because, more variation increases the species fitness, the ability to survive and reproduce. Allowing the organism to pass on their beneficial traits (advantageous traits), to their offspring.
