WebFalse This tree shows that bacteria evolve into green algae, which evolve into plants, and so on. False The bacteria that are alive today are the common ancestors of all other organisms. False. Which phylogenetic tree highlights the most recent common ancestor of all animals with four limbs (where limbs include legs, arms, and wings)? ... All known forms of life are based on the same fundamental biochemical organization: genetic information encoded in DNA, transcribed into RNA, through the effect of protein- and RNA-enzymes, then translated into proteins by (highly similar) ribosomes, with ATP, NADPH and others as energy sources. Analysis of small sequence differences in widely shared substances such as cytochrome c further supports universal common descent. Some 23 proteins are found in all org…
