Doyle's work involves oversight of the geological sites of the greater Burren area, education programmes for school children and adults, including a summer Field Geology course and support for local participation in the Irish Young Scientist Exhibition, production of book and other printed material for the geopark, interaction with professional ...
The Burren (/ ˈ b ʌr ə n / BURR-ən; Irish: Boirinn, meaning 'rocky district') [1] is a karst/glaciokarst landscape centred in County Clare, on the west coast of Ireland. [2] It measures around 530 square kilometres (200 sq mi), within the circle made by the villages of Lisdoonvarna, Corofin, Gort and Kinvara. [3]
The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
All life on Earth is based on carbon and is built from organic compounds including the amino acids used to create proteins and nucleobases. A nucleobase is a nitrogen-containing compound that ...
A similar developmental origin suggests they are the same structure, and thus likely derived from a common ancestor. When a group of organisms share a homologous structure that is specialized to perform a variety of functions to adapt different environmental conditions and modes of life, it is called adaptive radiation.
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.
The biological organisation of life is a fundamental premise for numerous areas of scientific research, particularly in the medical sciences. Without this necessary degree of organisation, it would be much more difficult—and likely impossible—to apply the study of the effects of various physical and chemical phenomena to diseases and ...
Fossils provide evidence that accumulated changes in organisms over long periods of time have led to the diverse forms of life we see today. A fossil itself reveals the organism's structure and the relationships between present and extinct species, allowing palaeontologists to construct a family tree for all of the life forms on Earth.
