Between 390 and 360 million years ago, the descendents of these organisms began to live in shallower waters, and eventually moved to land. As they did, they experienced natural selection that shaped many adaptations for a terrestrial way of life.

When did animals move onto land?
500 million years ago Fossil evidence shows that animals were exploring the land at this time. The first animals to do so were probably euthycarcinoids – thought to be the missing link between insects and crustaceans.
When did the first animals leave the water?
The date for the first evidence of the transition of animal life from sea to land has long stood at 400 million years ago.
What animal moved from water to land first?
Around 365 million years ago, they finally made the transition from water to land. The first vertebrates to live on land were amphibians. They evolved from lobe-finned fish. You can compare a lobe-finned fish and an amphibian in Figure below.
How did animals move from water to land?
Jennifer Ouellette. Life on Earth began in the water. So when the first animals moved onto land, they had to trade their fins for limbs, and their gills for lungs, the better to adapt to their new terrestrial environment. In air, eyes can see much farther than they can under water.
Why did animals transition from water to land?
The vertebrate land invasion refers to the aquatic-to-terrestrial transition of vertebrate organisms in the Late Devonian epoch. This transition allowed animals to escape competitive pressure from the water and explore niche opportunities on land.
When did fish walk on land?
Around 375 million years ago, some fish began an extraordinary transformation that would change the history of life on Earth: their fins evolved into something like limbs that enabled them to walk on land.
When did fish crawl onto land?
Around 370 million years ago, late in what we call the Devonian era, the first fish began to crawl out of the primordial ooze and onto the shores of a new, terrestrial world.
When did fish move to land?
In the Middle Devonian, roughly 385 million years ago, the first vertebrates began making their way out of water.
Why did animals come to land?
It may have been to escape predators or at least lay eggs in a safer place. Maybe there were new food sources they were really trying to access. The land was a whole unexplored ecosystem at this time so there were many opportunities.
What was the first land animal?
The earliest known land animal is Pneumodesmus newmani, a species of millipede known from a single fossil specimen, which lived 428 million years ago during the late Silurian Period. It was discovered in 2004, in a layer of sandstone near Stonehaven, in Aberdeenshire, Scotland.
When did the first land animals appear?
It was during the Paleozoic Era that plants (first known from microfossils called cryptospores that appear in the mid-Ordovician, about 470 million years ago; Wellman and Gray 2000) and animals (known from Silurian fossils, at least 423 million years ago; Wilson and Anderson 2004) began to colonize the land.
How did fish go from water to land?
Fossils have been found that show fish developing into amphibians and moving out of the water and onto the land. Those fish that had the flexibility to allow them to move out onto land were able to remove themselves from a very competitive environment and into a new habitat of plants and insects.
How long ago did plants first move to land?
The researchers found that land plants had evolved on Earth by about 700 million years ago and land fungi by about 1,300 million years ago — much earlier than previous estimates of around 480 million years ago, which were based on the earliest fossils of those organisms.
What is found in the 375 million year old fish?
The discovery of well-preserved pelves and a partial pelvic fin from Tiktaalik roseae, a 375 million-year-old transitional species between fish and the first legged animals, reveals that the evolution of hind legs actually began as enhanced hind fins.
