Evolutionary ecology is a general term that may mean very different things to different people. The main focus of it is to create a timescale and boundary between the ecological and evolutionary phenomena. Evolutionary ecologists study various and numerous aspects that include the size, age at maturity, breeding systems, life history, and evolution in the environments. Small comparative studies made so as to create small scale comparatives among the species or the population informed by the phylogenetic analysis. It has enlarged the scope at which the evolutionary ecology included the phenomena above the level of the species in quest to understand the link between macro and micro evolutionary processes.
Evolution and ecology share a broad relationship with both of the fields recognizing the perspective of interdisciplinary. Population dynamics can influence the selection of one generation to the other but still at the same time and period evolves and gives feedback on the population dynamics. Reflecting on some of the range of influences that evolution has on the ecology, and those that the ecology has on the evolution are explicit questions with the evolutionary component in them. They appear in the populations.

Ecology is the study of the living organisms and the relation to their surroundings. Evolution is a process in which an individual species and ecosystem changes over a period through natural selection that are acted up by dynamic forces. The relation between the ecology and the evolutionary biology is fundamental and intimate. Evolution helps organisms develop in a diversified way. They have different characteristics from their forebearers and have a central theme in biology. The various branches of biology point out the facts that the species have experienced gradual physical changes which have been definite. Evolutionary biology has various theories that explain the physical changes of different species. Changes in the surroundings have been a great influence that has forced the organisms to adapt and change in the way that they interact with one another. An ecosystem that contains both the environment and all its inhabitants can hold hundreds and even thousands of different species. The reason the historical relationships are important in studying ecology and evolutionary biology is to provide baseline for comparative studies. Whatever the evolutionary or ecological differences that one is interested in, the differences or the similarities need to be assessed. The comparative studies help in disentangling the many differences that are possible to identify between the two populations.
A crucial way to understand the patterns of geographical variations between different species is by understanding their mating system and various community structures. In ecology and evolutionary biology it is important to expand studies to a species that could be related to the one that is being studied. This research should explore both the molecular and organism levels. The relation between the ecology and the evolutionary biology is fundamental and intimate. Evolution involves different species, and plants develop in a diversified way. They have different characteristics from their forebearers and have a central theme in biology. Ecologists and evolutionists are more interested in increasing the time frame for their research so that they can study other similar species. The differences between the species should be clear and well determined to fulfill an understanding of the diversity of the species at the molecular level. Different ways to consider the relationship may be used such as using ribosomal DNA, and chaconne syntheses. The results from the genes make it possible to reason that the work is informed and reasonable.
Life history is the ensemble of the characteristics that determine the timing of various crucial events in the existing of an orgasm. Some of these relevant schedules are germination in seeds, length of reproduction period in animals and vegetation periods. Life history broadly researchers the theoretical and empirical investigations of the age and size at reproduction. Understanding the life cycle of species links them to various paradigms in the evolutionary ecology. Through functional biology, we can verify how well the organisms have adapted to a particular environment. Historical evolutionary biology of species examines how the species or plants’ life history gets maintained and how it is inherited from the ancestor organisms.
Studies in ecology and evolutionary biology focus mainly on the analysis of bodies on a level of analysis and addressing issues on the ecosystem. Natural selection plays a significant role in shaping the differences that are among populations. These differences lead to the prediction of what a consistent link between the phenotype and the organism and the habitat that they live. It is important to characterize the types of natural selection under the field conditions. The first step measures the range using standard statistical methods. It provides no clue to what the environmental factors that are causing selection to occur. Measuring range and uncovering the causal mechanisms of selection are a crucial objective to researching.
Quantitative genetics is a statistical approach to the study of the characteristics between multiple loci. The goals of the quantitative genetics study are to assess the degree and the type of genetic variation for traits that are phenotypic in a natural population. It also evaluates potential response to different known pressures on the populations. Heritability, selection of gradients and the genetic variance are some of the key concepts of the quantitative genetics. An approach to Quantitative genetics to the study of evolution of natural populations is characterized by definite methodological limits. It focuses on much theoretical and empirical research.
