An evolutionary grade is a group of species united by morphological or physiological traits, that has given rise to another group that has major differences from the ancestral group's condition, and is thus not considered part of the ancestral group, while still having enough similarities that we can group them under the same clade.
Evolutionary grade – Non-monophyletic grouping of organisms united by morphological or physiological characteristics Lineage (evolution) – Sequence of populations, organisms, cells, or genes that form a line of descent
Evolutionary taxonomy, evolutionary systematics or Darwinian classification is a branch of biological classification that seeks to classify organisms using a combination of phylogenetic relationship (shared descent), progenitor-descendant relationship (serial descent), and degree of evolutionary change.
Life history theory draws on an evolutionary foundation, and studies the effects of natural selection on organisms, both throughout their lifetime and across generations. [8] It also uses measures of evolutionary fitness to determine if organisms are able to maximize or optimize this fitness, [ 9 ] by allocating resources to a range of ...
Current research in evolutionary biology covers diverse topics and incorporates ideas from diverse areas, such as molecular genetics and computer science. First, some fields of evolutionary research try to explain phenomena that were poorly accounted for in the modern evolutionary synthesis .
From March 2011 to December 2012, if you bought shares in companies when Mukesh D. Ambani joined the board, and sold them when he left, you would have a -16.7 percent return on your investment, compared to a 9.2 percent return from the S&P 500.
The tree of life or universal tree of life is a metaphor, conceptual model, and research tool used to explore the evolution of life and describe the relationships between organisms, both living and extinct, as described in a famous passage in Charles Darwin's On the Origin of Species (1859). [1]
