What else can I help you with?
According to the concept of punctuated equilibrium the sudden appearance of a new species in the fossil record means that?
there was a relatively rapid period of evolutionary change followed by long periods of stability without much change in the species. This suggests that evolution does not always happen gradually and continuously, but rather in punctuated bursts of change.
Which of the following can result in instant speciation?
Allopatric speciation and sympatric speciation are two factors. Allopatric speciation occurs when physical barriers are formed, separating the specie. This will cause the specie to evolve at different rates causing a new specie to form. Sympatric speciation is less likely to occur when comparing it to allopatric. In sympatric speciation is no longer physical but generic. For example a mutation in the genetic order of the specie (which does not happen as often as physical barriers), and a different mating preference/season.
What is the name given to a row of elements in the periodic table with densities and melting points that change gradually and predictably?
This is a period.
How was the Triassic period a transitional time period during the Mesozoic era?
I believe that dont know
Where there any meteors during the Jurassic era?
Yes, there is evidence that suggests meteors did hit the Earth during the Jurassic era. Some scientists believe that a meteor impact may have contributed to the mass extinction event that marked the end of the Jurassic period.
Scientists believe that humans arrived on Earth during which Period?
A. Quaternary
When do scientists think that humans first appeared in the geologic time scale?
Scientists believe that humans first appeared during the Quaternary period, specifically in the Pleistocene epoch. This period started about 2.6 million years ago and continues to the present day.
What is Parkinson's disease's incubation period?
Scientists have no factual evidence regarding the incubation period for Parkinson's disease. Some believe it can build up over a lifetime while others think there is no incubation period.
Scientists believe that humans arrived on earth during what period. A quaternary. B tertiary. C cretaceous. D triassic?
scientists belive human beings first developed on earth during :- A. quaternary.
Scientists believe the earth was formed during what era?
Scientists believe that the Earth was formed during the Hadean Eon, which is estimated to have occurred between 4.6 to 4.0 billion years ago. This period was characterized by intense meteorite bombardment, high temperatures, and volcanic activity.
How did the ambulocetus become extinct?
Bambiraptor lived in the Late Cretaceous period and i believe died out in the mass K-T extinction. this extinction would be where scientists believe that a meteor hit the Yucatan Peninsula.
Where do scientists believe plants evolved?
Scientists believe that plants evolved on land from green algae, specifically from a group called charophytes. This transition from water to land occurred around 450 million years ago during the Ordovician period.
Where do scientists think the Stegosaurus live?
Scientists believe that the natural habitat of the Stegosaurus was the area that now makes up modern day Europe and western North America. The dinosaur lived during the late Jurassic period.
Is it normal to have diarrhea during your period for a fifteen year old?
Yes. Many (scientists/doctors) believe it is due to the contractions of cramps mingling between the Uterus and Intestines.
What period of history do scientists think jaws developed?
Scientists believe that jaws likely developed during the Silurian period, around 430 million years ago, from modifications of the anterior gill arches of early fish-like organisms. This evolutionary development allowed for more efficient feeding and predation, leading to the diversification and success of jawed vertebrates.
When do scientists believe life originated on Earth?
Scientists believe life originated on Earth around 3.5 to 4 billion years ago. This is based on fossil evidence of simple life forms found in rocks dating back to that time period and the presence of key molecules necessary for life in early Earth environments.
According to the concept of punctuated equilibrium the sudden appearance of a new species in the fossil record means that?
there was a relatively rapid period of evolutionary change followed by long periods of stability without much change in the species. This suggests that evolution does not always happen gradually and continuously, but rather in punctuated bursts of change.
