Then God blessed Noah and his sons, saying to them, Be fruitful and increase in number and fill the earth. Genesis 9:1 NIV
Known as the Weald-Artois Anticline (land bridge), it allowed a wide
range of animals, including hippopotamuses, to migrate from mainland
Europe into Britain. This land bridge was washed away around 450 ka ago
(in the evolutionary timeline) due to a huge Ice Age lake bursting just
to the north of it in the southern North Sea.
The resulting deposition and extensive erosional scars in the seabed
are found in (and formed) the English Channel just to the south of where
the land bridge was situated. This is a very clear example of the power
of water acting quickly to remove a huge geological structure.
In the evolutionary timeline there are numerous glacial and 
interglacial
periods during the five ice ages. It was during the last period of
glaciation, around 20 ka ago, that Britain was once again connected to
North West Europe. This was an exposed area of low-lying land called
Doggerland, which at its maximum ran between England, France, Germany,
Holland, and Denmark. The existence and habitation of Doggerland is well
attested to, with remains of mammoths, lions, and flint tools being
regularly dredged up by fishing trawlers in the North Sea.....the Storegga Slide, triggered by an earthquake just off the coast of
Norway, then caused a tsunami in the North Sea. It was assumed that this
wiped the islands away.
However, the researchers, based on new sediment
samples from the east coast of England, say this may not have been the
case. They suggested that floodwaters from the tsunami withdrew, didn’t
cause the islands final demise, and the landscape recovered temporarily.
Instead, “the eventual inundation of the remaining parts of Doggerland
resulted from the inexorable sea-level rise, rather than a lasting
inundation from the Storegga tsunami”.
Biblical creationists have long explained that there was only one Ice
Age (lasting between 500–700 years), which occurred directly after the
Noahic Flood, around 4.5 ka ago.
During this time,
---the landscape around
coastal areas changed rapidly, 
---with water from the sea being stored on
land as an ice sheet 1–2 km high,
---which later melted and returned to the
sea.
---The chalk land bridge connecting modern-day England and France
would indeed have allowed animals and humans to cross until it was
washed away.
---The area directly behind the land bridge where the huge Ice Age lake
burst, up to the edge of the ice sheet, would have briefly exposed an
area of low laying land, now called Doggerland.
From the material
dredged up, it appears to have been temporarily inhabited before the
water level rose to its current height, once again covering it. Of
course, for people, animals, and plant life to move into, inhabit and
grow e.g., this would be able to take place quickly as they would have
been living in the surrounding higher areas already.
As fishermen continue to dredge up material belonging to Noah’s
descendants and the remnants of this early post-Flood civilization
on the vast plain now called Doggerland, it may provide us with further
information as to their lifestyle and movement into Northern Europe."
