evolve

The three species evolved from a single ancestor.

Primates evolve over millions of years. I evolve in seconds.

Why did animal life evolve so quickly?

During a geologically brief 100-million-year period, all modern animal groups (along with other animals that are now extinct) evolved.

And it…it's probably a kind of tree from which other trees that grow in Australia today evolved.

Many millions of years after ferns evolved (but long before the Hawaiian Islands were born from the sea), another kind of flora evolved on Earth: the seed-bearing plants.

We know whales are mammals and that they evolved from land creatures.

But the language of everyday life was evolving in Europe and at a certain point in the middle ages, it was really only aristocrats,merchants, and clergy who can deal with Latin.

Sometimes primary group relationships evolve out of secondary group relationships.

Another issue is that languages evolve very gradually, but the tree model makes it look like they evolve over night, like there was a distinct moment in time when a mother language clearly broke off into daughter languages.

And in adapting to extreme climates, like Maine in the winter time, animals can evolve in pretty interesting ways.

And to survive in that sort of environment, animals have to adapt, to evolve in response to their surroundings.

In the years since the Pleistocene epoch, native species have adapted to the changing environmental there, plants, smaller animals, they have been evolving without megafauna for millennia.

So it is conceivable that the pronghorn antelope would have continued to evolve, get faster maybe, if the cheetahs were still around.

OK. For today, let's look at a reptile, a predator that hasn't evolved much in the last seventy million years.

So the most successful groups of land plants are those that evolved methods of fertilized sex cell dispersal that are independent of water and structures that protest developing embryos from drying out.

So primates and birds' brains have evolved along different tracks, but ended up with similar abilities.

The physical structure of species competing for resources in the same ecological niche tends to gradually evolve in ways that allow them to occupy different niches.

The benefits of play must outweigh costs, or play would not have evolved, according to Darwin's theory.

Horses evolved in discrete steps, each of which persisted almost unchanged for millions of years and was eventually replaced by a distinctive newer model.

The old ruling families were being displaced by an evolving centralized government.

Studies of how stars evolve suggest that the early Sun was only about 70 percent as luminous as it is now, so the temperature in Venus' early atmosphere must have been quite a bit lower.

In fact, several scientists have suggested that the duckbill dinosaurs and horned dinosaurs, with their complex battery of grinding teeth, evolved to exploit this new resource of rapidly growing flowering plants.

For example, some have blamed dinosaur extinction on the development of flowering plants, which were supposedly more difficult to digest and could have caused constipation or indigestion - except that flowering plants first evolved in the Early Cretaceous, about 60 million years before the dinosaurs died out.

Accumulated evidence indicates that all thirteen finch species evolved from a single small population of ancestral birds that colonized one of the islands.

When oceanic islands are far enough apart to permit populations to evolve in isolation, but close enough to allow occasional dispersions to occur, they are effectively outdoor laboratories of evolution.

This mode of evolving new species is called allopatric speciation.

So, these fish had already evolved one of the prime requisites for living on land: the ability to use air as a source of oxygen.

Alternative methods of active or passive prey capture have been evolved, including trapping and seizing prey, entangling prey, and sticky tentacles.

One of the frustrating things about archaeology, especially for beginning students, is that theories are constantly evolving.

Cows and goats have evolved highly specialized digestive systems that allow them to metabolize cellulose.

When the Maori arrived in New Zealand, they encountered birds that had been evolving for 80 million years without the presence of mammalian predators.

Snakes and most mammals evolved after the separation.

However, the twins evolved differently largely because of differences in their distance from the Sun.

So one of the more common topics that comes up in world history because it's had a pretty dramatic effect on how different societies evolved over long periods of time is cultural diffusion.

Over time, the symbols became more numerous, varied, and abstract and came to represent more than trade commodities, evolving eventually into cuneiform writing.

Over many thousands of years, the symbols evolved through several stages of abstraction until they became wedge- shaped (cuneiform) signs on clay tablets, recognizable as writing.

Each school must evolve its own way of working.

A closely related theory sees theater as evolving out of dances that are primarily pantomimic, rhythmical or gymnastic, or from imitations of animal noises and sounds.

And these clear glass reading stones evolved into the eyeglasses we know today.

Whitewares produced in Hebei and Henan provinces from the seventh to the tenth centuries evolved into the highly prized porcelains of the Song dynasty (AD. 960-, long regarded as one of the high points in the history of China's ceramic industry.

Our ties with people often deepen as we interact with them across time and gradually evolve interlocking habits and interests.

Such theories imply that the Indo-European languages evolved not in Neolithic (10,000 to 3,000 B.C.) Anatolia, but among the foraging communities of the cultures in the region of the Don and Dnieper rivers, which took up stock breeding and began to exploit the neighboring steppes.

Alternative strategies have evolved in some plants, such as those that produce fewer but larger seeds that are dispersed to suitable sites by birds or small mammals or those that produce long-lived seeds.

However, no group or species can maintain its dominance indefinitely, and when, after over 200 million years, the age of dinosaurs came to a dramatic end about 65 million years ago, mammals began to flourish, evolving from relatively few types of small terrestrial animals into the myriad of diverse species, including bats and whales, that we know today.
