However, groups such as the echinoderms sea stars, urchinsmolluscs clams, snailsarthropods crustaceans, insectscorals, ectoprocts, brachiopods, and vertebrates have left rich fossil records.

We discuss various ways in which these trees are developed in Chapter 2. Cells with a variety of membrane-enclosed organelles e. The discovery that organisms with a cell nucleus constitute a natural group divided the living world neatly into two categories, the prokaryotes those organisms lacking membrane-enclosed organelles and a nucleus, and without linear chromosomesand the eukaryotes those organisms that do possess membranebound organelles and a nucleus, and linear chromosomes.

The master regulatory genes of plants are not members of the homeobox gene family, but belong to the MADS box family of transcription factor genes. For example, Archaea differ from both Eubacteria and Eukaryota in the composition of their ribosomes, in the construction of their cell walls, and in the kinds of lipids in their cell membranes.
Download The ciliated protozoa;: Eukaryotic single-celled microorganisms and certain algae. The fossil record tells us that metazoan life had its origin in the Proterozoic eon, at least million years ago, although trace fossils suggest that the earliest animals might have originated more than 1.

It used to be thought that the Proterozoic was a time of only a few simple kinds of life; hence the name. Never with membrane-enclosed organelles or nuclei, or a cytoskeleton; none are methanogens; some use chlorophyll-based photosynthesis; with peptidoglycan in cell wall; with a single known RNA polymerase.
