Sentence examples for past organisms from inspiring English sources

Recently developed global climate models are capable of simulating past climate variables (e.g., precipitation and temperature), and geographic information system (GIS) tools can then be used to interpolate these data to model the niches of past organisms into paleoclimate zones.

Because past organisms and environments cannot be observed directly, much paleoecological research is concerned with determining past occurrences, distributions, and abundances of organisms and reconstructing past populations, communities, landscapes, environments, and ecosystems using geological and biological evidence.

Paleontology seeks information about several aspects of past organisms: "their identity and origin, their environment and evolution, and what they can tell us about the Earth's organic and inorganic past".

Furthermore, over time, an organism can evolve and to explain such evolution phylogenetic networks, mostly trees, have been constructed involving present and past organisms.

In the past, model organisms were used exclusively for understanding the cellular and molecular basis for disease; increasingly, they are being used directly to discover new therapies.

In the past, model organism work has focused on understanding the basis of disease and on generating the models.

However, genome deletion events have happened in the past and many organisms have lost a number of important enzymes necessary for de novo biosynthetic pathways.

Serological methods to measure past infection by organisms such as C. trachomatis, N. gonorrhoea and HPV may underestimate actual exposure due to poor sensitivity.

A major aim of ecological and evolutionary systems biology would be to 'predict' both future and past responses of organisms to changing environments within the ecological and evolutionary contexts.
