The short answer is 1000 years is probably not long enough. Evolution is a very slow process. Even very minor changes can take hundreds of thousands to millions of years to develop. Evolutionary processes span many thousands of generations.12-Oct-2015
Can evolution happen over 1000 years?
Can evolution happen in 100 years?
As argued in a recent thread (https://www.researchgate.net/post/How_to_handle_a_parasitic_protist_species_insufficiently_described_100_years_ago_and_probably_found_again), 100 years is enough for an organism to evolve, as to thrown into confusion the identification of the species described a century ago.
What will humans look like in 1000000 years?
In the year 1 million, Earth's continents will look roughly the same as they do now and the sun will still shine as it does today. But humans could be so radically different that people today wouldn't even recognize them, according to a new series from National Geographic.
How far back does evolution go?
Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.
What is the oldest evolution?
Cyanobacteria are the oldest existing species in the world. These bacteria are believed to be the Earth's oldest known life form. Fossilized stromatolites – a type of layered rock made up of microbial mats of microorganisms – dating back to over 3.5 billion years ago contain evidence of cyanobacteria activity.
How did humans look 10000 years ago?
Humans looked essentially the same as they do today 10,000 years ago, with minor differences in height and build due to differences in diet and lifestyle. But in the next 10 millennia, we may well have refined genetic 'editing' techniques to allow our children to all be born beautiful and healthy.
What will it be like in 100 years?
In 100 years, the world's population will probably be around 10 – 12 billion people, the rainforests will be largely cleared and the world would not be or look peaceful. We would have a shortage of resources such as water, food and habitation which would lead to conflicts and wars.
What will happen in 1 billion years?
In about one billion years, the solar luminosity will be 10% higher than at present. This will cause the atmosphere to become a "moist greenhouse", resulting in a runaway evaporation of the oceans. As a likely consequence, plate tectonics will come to an end, and with them the entire carbon cycle.
What year will humans go extinct?
Current population predictions vary. But the general consensus is that it'll top out sometime midcentury and start to fall sharply. As soon as 2100, the global population size could be less than it is now. In most countries—including poorer ones—the birth rate is now well below the death rate.
