Cladistics (/ k l ə ˈ d ɪ s t ɪ k s /, from Greek κλάδος, cládos, "branch") is an approach to biological classification in which organisms are categorized in groups ("clades") based on the most recent common ancestor.Hypothesized relationships are typically based on shared derived characteristics (synapomorphies) that can be traced to the most recent common ancestor and are not.

Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.Different characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation.

May 31, 2018  · Both cladograms and phylogenetic trees show the relationships between organisms, but their main difference is how they compare them. Cladograms are concerned with the way organisms are related to common ancestors through shared characteristics. Phylogenetic trees compare organisms over evolutionary time and the amount of change that has occurred over time to figure out the relationships.

The green algae and land plants form a monophyletic lineage (the chlorophytes) that contains both protistan and higher taxa ([Graham, 1996][1]). An important issue regarding the evolution of this green lineage that still remains in question is the identity of the green algal (i.e. flagellate)

According to the theory of common descent, modern living organisms, with all their incredible differences, are the progeny of one single species in the distant past. In spite of the extensive variation of form and function among organisms, several fundamental criteria characterize all life. Some of.

Homo naledi is a recently discovered species of fossil hominin from South Africa. A considerable amount is already known about H. naledi but some important questions remain unanswered. Here we report a study that addressed two of them: “Where does H. naledi fit in the hominin evolutionary tree?” and “How old is it?” We used a large supermatrix of craniodental characters for both early.
