Evolutionary biology

General overview The evidence for evolution Darwin and other 19th-century biologists found compelling evidence for biological evolution in the comparative study of living organisms, in their geographic distribution, and in the fossil remains of extinct organisms. The amount of information about evolutionary history stored in the DNA and proteins of living things is virtually unlimited; scientists can reconstruct any detail of the evolutionary history of life by investing sufficient time and laboratory resources.

January 7, ] volution is the cornerstone of modern biology. It unites all the fields of biology under one theoretical umbrella. It is not a difficult concept, but very few people — the majority of biologists included — have a satisfactory grasp of it. One common mistake is believing that species can be arranged on an evolutionary ladder from bacteria through “lower” animals, to “higher” animals and, finally, up to man. Mistakes permeate popular science expositions of evolutionary biology.

Mistakes even filter into biology journals and texts.

Cell biology

It was used again in in a work entitled Philosophiae naturalis sive physicae: The first German use, Biologie, was in a translation of Linnaeus’ work. The term came into its modern usage with the six-volume treatise Biologie, oder Philosophie der lebenden Natur —22 by Gottfried Reinhold Treviranus , who announced: The science that concerns itself with these objects we will indicate by the name biology [Biologie] or the doctrine of life [Lebenslehre].

Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution. Despite the complexity of the science, there are certain unifying concepts that consolidate it into a single, coherent field. Biology recognizes the cell as the basic unit of life, genes as.

The candidate may also be required to develop an undergraduate or graduate course in their area of expertise.

Evolution within a Lineage

History[ edit ] Cells, which were once invisible to the naked eye, were first seen in 17th century Europe with the invention of the compound microscope. Robert Hooke was the first person to term the building block of all living organisms as “cells” after looking at cork. Scientists have struggled to decide whether viruses are alive or not. Viruses lack common characteristics of a living cell, such as membranes, cell organelles , and the ability to reproduce by themselves. The techniques by which cells are studied have evolved.

Advancement in microscopic techniques and technology such as fluorescence microscopy , phase-contrast microscopy , dark field microscopy , confocal microscopy , cytometry , transmission electron microscopy , etc.

1. INTRODUCTION – OVERVIEW – Biology as a science deals with the origin, history, process, and physical characteristics, of plants and animals: it includes botany, and zoology. A study of biology includes the study of the chemical basis of living organisms, related sciences include microbiology and organic chemistry.

A new cell wall forms between the two membranes. About one-third of all plant matter is cellulose, which is the most abundant organic compound on earth. It is composed of the brain and spinal cord. They range in size from 2 mm to 12 cm in length, depending on the form in question, and occupy a broad range of marine environments. Most chaetognaths are transparent.

A chimera can be produced, for example, by pushing together two genetically distinct early-stage embryos and then allowing them to develop; 2 a molecule composed of molecules of two distinct types e. It is also found in many mollusks , for example, in radulae and in the beaks of cephalopods.

See Article History Biology, study of living things and their vital processes. The field deals with all the physicochemical aspects of life. The modern tendency toward cross-disciplinary research and the unification of scientific knowledge and investigation from different fields has resulted in significant overlap of the field of biology with other scientific disciplines. Modern principles of other fields—chemistry, medicine, and physics, for example—are integrated with those of biology in areas such as biochemistry , biomedicine, and biophysics.

Thus, while it is custom to separate the study of plants botany from that of animals zoology , and the study of the structure of organisms morphology from that of function physiology , all living things share in common certain biological phenomena—for example, various means of reproduction, cell division , and the transmission of genetic material.

The statistician Ronald Fisher — helped to form the modern evolutionary synthesis of Mendelian genetics and natural selection. The idea of evolution by natural selection was proposed by Charles Darwin in , but evolutionary biology, as an academic discipline in its own right, emerged during the period of the modern synthesis in the s and s. In the United States , many universities have created departments of molecular and cell biology or ecology and evolutionary biology, in place of the older departments of botany and zoology.

Palaeontology is often grouped with earth science. Haldane — helped to create the field of population genetics. Microbiology too is becoming an evolutionary discipline, now that microbial physiology and genomics are better understood. The quick generation time of bacteria and viruses such as bacteriophages makes it possible to explore evolutionary questions. Many biologists have contributed to shaping the modern discipline of evolutionary biology. Theodosius Dobzhansky and E. Ford established an empirical research programme.

Cell biology

Biology comes from the Greek word for life, bis, and the Greek word for thought or reasoning, logos. It denotes the science that studies life, the properties and processes that sustain life, the evolutionary history of life, and particular living organisms. It is a science of enormous diversity, breadth, and heterogeneity unified only by the conceptual framework provided by the theory of evolution.

Indeed, as famously noted in by the Russian evolutionary geneticist Theodosius Dobzhansky — , “Nothing in biology makes sense except in the light of evolution”—a quote now replicated in so many university-level textbooks that it is almost a dictum in modern biology.

Darwin, CharlesOverview of Charles Darwin’s life, with a focus on his work involving evolution. The following sections identify the most productive of these sources and illustrate the types of information they have provided. The fossil record Paleontologists have recovered and studied the fossil remains of many thousands of organisms that lived in the past.

This fossil record shows that many kinds of extinct organisms were very different in form from any now living. It also shows successions of organisms through time see faunal succession, law of ; geochronology: Determining the relationships of fossils with rock strata , manifesting their transition from one form to another. When an organism dies, it is usually destroyed by other forms of life and by weathering processes.

On rare occasions some body parts—particularly hard ones such as shells, teeth, or bones—are preserved by being buried in mud or protected in some other way from predators and weather. Eventually, they may become petrified and preserved indefinitely with the rocks in which they are embedded. Methods such as radiometric dating —measuring the amounts of natural radioactive atoms that remain in certain minerals to determine the elapsed time since they were constituted—make it possible to estimate the time period when the rocks, and the fossils associated with them, were formed.
