The Pliocene Epoch (fifth epoch of the tertiary period) lasted from about 5.3 to 2.6 million years ago. Tertiary Plants. The tertiary plants closely resemble the plants that we have at present. The warmer climate of the tertiary period, in the beginning, favored dense forests. As the climate cooled, it opened woodland and grassland became abundant.

The 2030 Agenda for Sustainable Development, adopted by all United Nations Member States in 2015, provides a shared blueprint for peace and prosperity for people and the planet, now and into the future. At its heart are the 17 Sustainable Development Goals (SDGs), which are an urgent call for action by all countries - developed and developing - in a global partnership.

The Cretaceous–Paleogene (K–Pg) boundary, formerly known as the Cretaceous–Tertiary (K–T) boundary, is a geological signature, usually a thin band of rock containing much more iridium than other bands. The K–Pg boundary marks the end of the Cretaceous Period, the last period of the Mesozoic Era, and marks the beginning of the Paleogene Period, the first period of the …

The geologic time scale, or geological time scale, (GTS) is a representation of time based on the rock record of Earth.It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists ...

The Cenozoic (/ ˌ s iː n ə ˈ z oʊ. ɪ k, ˌ s ɛ n-/ SEE-nə-ZOH-ik, SEN-ə-; lit. 'new life') is Earth's current geological era, representing the last 66 million years of Earth's history. It is characterized by the dominance of mammals, birds and flowering plants, a cooling and drying climate, and the current configuration of continents.It is the latest of three geological eras since ...

Online exhibits: Geologic time scale. The Cenozoic Era. The Cenozoic Era is the most recent of the three major subdivisions of animal history. The other two are the Mesozoic and Paleozoic Eras. The Cenozoic spans only about 65 million years, from the end of the Cretaceous Period and the extinction of non-avian dinosaurs to the present. The Cenozoic is sometimes called …

Dinosaurs lived on all of the continents. At the beginning of the age of dinosaurs (during the Triassic Period, about 230 million years ago), the continents were arranged together as a single supercontinent called Pangea. During the 165 million years of dinosaur existence this supercontinent slowly broke apart. Its pieces then spread across the globe into a nearly …

Clustal Omega is a new multiple sequence alignment program that uses seeded guide trees and HMM profile-profile techniques to generate alignments between three or more sequences. For the alignment of two sequences please instead use our pairwise sequence alignment tools. Important note: This tool can align up to 4000 sequences or a maximum file size of 4 MB.

The three-sector model in economics divides economies into three sectors of activity: extraction of raw materials (), manufacturing (), and service industries which exist to facilitate the transport, distribution and sale of goods produced in the secondary sector (). The model was developed by Allan Fisher, Colin Clark, and Jean Fourastié in the first half of the 20th century, and is a ...
