Evolutionary ecology. A phylogenetic tree of living things. Evolutionary ecology lies at the intersection of ecology and evolutionary biology. It approaches the study of ecology in a way that explicitly considers the evolutionary histories of species and the interactions between them. Conversely, it can be seen as an approach to the study of ...
Ecology and evolutionary biology is an interdisciplinary field of study concerning interactions between organisms and their ever-changing environment, including perspectives from both evolutionary biology and ecology. This field of study includes topics such as the way organisms respond and evolve, as well as the relationships among animals ...
Evolutionary biology is the subfield of biology that studies the evolutionary processes (natural selection, common descent, speciation) that produced the diversity of life on Earth. It is also defined as the study of the history of life forms on Earth. Evolution holds that all species are related and gradually change over generations. [1]
v. t. e. Ecology (from Ancient Greek οἶκος (oîkos) 'house' and -λογία (-logía) 'study of') [A] is the natural science of the relationships among living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere levels.
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. [3]
Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. [25][26][27] 2. Adaptedness is the state of being adapted: the degree to which an organism is able to live and reproduce in a given set of habitats. [28]
A phylogenetic tree, phylogeny or evolutionary tree is a graphical representation which shows the evolutionary history between a set of species or taxa during a specific time. [1][2] In other words, it is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon ...
Lineage (evolution) – Sequence of populations, organisms, cells, or genes that form a line of descent. Molecular phylogenetics – Branch of phylogeny that analyzes genetic, hereditary molecular differences. Most recent common ancestor – Most recent individual from which all organisms in a group are directly descended.
