In your opinion, what selective factors must be the same (or sufficiently similar) for anole evolution to converge independently into the same ecomorphs on each of the four caribbean islands? think of at least four such factors. the south american mainland has very different ecological niches than the islands we are studying. the mainland anoles have very different morphologies than the island anoles do. does this information support the theory of evolutionary convergence of anole ecomorphs? what does this information say about the requirement for similarity of environmental conditions?

During the winter, this species of fox has white fur, but in the summer, it has brown fur. what environmental change may have lead to this fox's fur color? snow cover increase in sun's brightness volcanic eruption global warming

The empty trna moves off and picks up another matching amino acid from the cytoplasm in the cell. the anticodon of the trna, with its attached amino acid, pairs to the codon of the mrna, which is attached to a ribosome. this sequence is repeated until the ribosome reaches a stop codon on the mrna, which signals the end of protein synthesis. the ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. when a second trna with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first trna and is bonded to the amino acid of the second trna.
