How long ago did the first plant exist on earth?
i think that the first planet existed 4.7billion years ago. Because the Sun's age is thought to be 5billion years ago and the earth 4.5billion, scientists know that Earth was not the first planet.
What are you still wondering about as you consider the similarities and differences between species?
As you think about the similarities and differences between species, you may still be wondering about the underlying reasons for these variations. Scientists continue to study how genetics, environment, and evolution play a role in shaping the traits of different species.
Why do scientists think the first living cells to appear on earth were probably anaerobic heterotraphs?
Scientists believe that the first living cells on Earth were likely anaerobic heterotrophs because early Earth lacked oxygen, and these organisms do not require oxygen for their metabolism. Anaerobic heterotrophs can obtain the carbon compounds they need for energy from organic molecules in their environment, making them well-suited for the conditions of early Earth.
How do scientists think symbiotic relationships evolved?
Scientists believe that symbiotic relationships evolved through a process of co-evolution, where two species develop a relationship that benefits both of them. This can happen gradually over time as each species adapts to the presence of the other, leading to mutually beneficial interactions that enhance their survival and reproduction. The specific mechanisms through which symbiotic relationships evolved vary depending on the species involved and the nature of their interaction.
Why do you think scientists are trying to find out more about how and were early humans lived?
Because they are scientists
Are the yeti or the abominable snowman exist?
Probably not but scientists think that there might be a similar being roaming the Earth.
Why do scientists think there are s few redwood species alive today?
Scientists believe that changes in the Earth's climate cause extinction of trees;P
How many animal species have become extinct in the past year?
Scientists have identified and catalogued around 1,500,000 to 2,000,000 species (of animals and plants), most of which are insects (most of which are beetles). However, those are only the species that have been identified and described, many, many, many more exist - some scientists think there are 10 million (10,000,000) species on Earth, and others think there are 100 million (100,000,000) species on Earth! Biodiversity (the number of living organisms on Earth) is an incredibly hard thing to count. There are places on the Earth that have hardly been explored at all where diversity (the numbers of species) is extremely high, places like the tropical rain forest. The really scary thing is that, mostly as a result of the activity of human beings (pollution and destruction of the environment), lots of these species are going extinct before we even get a chance to identify them in the first place
Why do scientists think earths core contain iron?
The iron nickel core has been determined to actually exist from the examination of meteorites, from the gravitational field of Earth, and from the Earth's density in comparison to its volume.

What do scientists think have happened to most ancient species?
The big bang
Why do scientists think horses became extint?
The species "native horse" did go extinct and that is what scientists are talking about. The "equus ferus'' species is still alive though.
How old do scientists think that earth is?
4.6 billion years
Why do scientists think earths core iron?

What do most scientists think the earth's inner core is madde of?
iron
Scientists think the first water vapor on Earth came from?
From the oceans
Why do some scientist believe aliens are real and do they have evidence?
Yes and No. Some scientists think that aliens don't exist, some do. If they do, then they also obviously believe in them on other planets. What do you think? I think that they do exist, why would us humans be the ONLY ones on planet Earth? Positiveness of Answer: 100% jokypants1
