Concept explainers

The history and science of origin and evolution comprise two events, the beginning of life and expansion of life. Our earth originated about 4.5 billion years ago. The term evolution is derived from two Latin words and means the act of unfolding or unrol…

Cladistics

Cladistics is a technique in the classification of organisms, where they are grouped into different clades. The proof for the relationships that are hypothesized is based on the shared derived characteristics known as synapomorphies. These characteristic…

Outgroups

Outgroups are significant in studying cladistics or phylogenetics (that describe the evolutionary relationship between different organisms). Further, it is also important to understand the differences and similarities between different organisms.

Taxonomy

It is the branch of biology that works with the identification of organisms at first, then naming, and classification of them into phenetic or phylogenetic groups (a classification system). In other words, it is the scientific study of biological diversi…

Phylogenetics

Phylogenetics is the scientific study of how various groups of organisms are related at the evolutionary level. It finds the relationship between various organisms based on their evolutionary similarities and differences. It is a part of the taxonomy. Al…

PERFORMANCE TASK: 1. Go online. Choose a group of organisms you are interested to work with (e.g. invertebrates); 2. In tabular form, list all the characters. Evaluate the characters (whether primitive or derived). 3. Remember that in building your cladogram, use only shared derived characters. 4. Construct your own cladogram.

Please do fast How old are the first recognizable mammals relative to the K/T boundary layer (i.e., extinction of the dinosaurs), and from what reptilian lineage did they evolve? Is this lineage the same reptilian lineage that gave rise to birds? How are these lineages distinguished? Hold old are the first fossil birds? What other plant/animal lineages first became widespread in the Tertiary that were less common in the Cretaceous?..
