Marine Evolution

Marine habitat is less explored, and hence, its biological diversity is far less known. The marine habitats are not constant due to their shifting nature, while the terrestrial habitats are more stable. Marine biology is the science that deals with the study of diverse marine species, their interactions, and behavioral characteristics.

It has been suggested that the current time should be made into a different period. In other words, it should not have been part of the Holocene period due to the extreme changes man has made to the earth. If you were a scientist tasked to give a name to the period of today what name would you give it and why?
For how long has there been life on Earth? For what percentage of time has life existed on Earth? For about how many years of geological time have human existed on earth?
Which of the following geologic periods is not part of the Paleozoic Era? the Carboniferous Period the Cambrian Period the Cretaceous Period the Devonian Period the Ordovician Period
Earth is about 4.5 billion years old. In order to characterize the events that happened in this very long time scale, scientists have developed the geologic time scale. Here, the age of Earth is divided into (1), which in turn divided into (2), and are further subdivided into (3). The geologic time scale is so-called since the different subdivisions are based on the fossil record.
The greatest mass extinction episode in the history of life occurred at what boundary? (a) Pliocene–Pleistocene (b) Permian–Triassic (c) Mesozoic–Cenozoic (d) Cambrian– Ordovician (e) Triassic–Jurassic
During which geologic eon was the Earth first colonized by living organisms? the Phanerozoic Eon the Proterozoic Eon the Archaean Eon the Hadean Eon none of the above
Why was it believed that life began in the seas and not in land or air? * Land and air were inhospitable places for life during the Hadean Eon. Land and air were inhospitable places for life during the Archean Eon. Land and air were inhospitable places for life during the Phanerozoic Eon. Land and air were inhospitable places for life during the Proterozoic Eon.
Earth’s history is divided into unequal time intervals. The boundaries between the intervals mark significant geological (very early Earth) or evolutionary events on Earth’s history. Example: The boundary between the Precambrian eon and the Phanerozoic eon is marked by the rapid evolution and diversification of organisms with hard body parts. The time intervals are eons, which are subdivided into eras. The eras are subdivided into periods. The periods are further subdivided into epochs (not shown on figure). What is our current eon ______________, era _______________, and period _______________ Age boundary between the Hadean eon and Archean eon __________________ Age boundary between Archean eon and Proterozoic eon __________________ Age boundary between Proterozoic eon and Phanerozoic eon ________________ Age boundary between Paleozoic era and Mesozoic era ____________________ Age boundary between Mesozoic era and Cenozoic era ____________________ What…
A paleontologist estimates that when a particular rock formed, it contained 12 mg of the radioactive isotope potassium-40. The rock now contains 3 mg of potassium-40. The half-life of potassium-40 is 1.3 billion years. From this information, you can conclude that the rock is approximately ______________ billion years old.
Why do scientists think that all forms of life on earthhave a common origin?
What argument convinced most scientists in the 1800s that Earth was more than 6,000 years old? The discovery of fossils Arguing that everyday observable geological processes (like erosion) could explain large geological features if they had occurred for millions of years, rather than large catastrophic events that happened suddenly The discovery that radioactive isotopes could be used to determine historical dates The discovery that Earth orbits around the sun, rather than the sun orbiting around Earth
Scientists are examining the possible role of a large asteroid in the cretaceous mass extinction event. A large asteroid strike would likely have caused rapid climate cooling and the diffusion of sunlight. which of the following statements are the best null and alternative hypotheses when scientists look at the geologic evidence of extinction related to the asteroid strike?
