if no the friends theory is wrong because pegions get their colour from nature as pegions are usually grey and white they might got a special colour from nature
if yes then the full theory will be wrong because any animals except chameleon cannot change his/her colour
Green algae (sing. alga) come in a heteromorph group of species and this is only a conventional name rather than biological classification. The group unites some predominant divisions like Chlorophyta and Charophyta.
Some species of Chlorophyta are considered to be the first ‘true’ plants by bridging between Protozoa and Plantae. Most of this division’s representatives are aquatic, they have chloroplasts and chlorophyll a and b, which are typical for plants. They could be unicellular, often colonial and even multicellular. The variety of the group is great in terms of their habitat, morpho-structure, reproductive system, etc. Some even live in symbiosis with fungi, but they are usually classified in a different division called Lichenophyta.
