Whales transitioned from land to water over millions of years due to evolutionary changes that allowed them to adapt to aquatic environments. This transition provided them with better access to food sources and protection from predators, ultimately leading to their successful survival and diversification in the oceans.

What is an an example of macroevolution?
Speciation is an example of macroevolution. The slow transition of land tetrapods to whales, the transition of small, many toed creatures into horses. These are not linear so much as branching progressions with the occasional dead end. Darwin's finches are a modern example of macroevolution by adaptive radiation.speciationBirds are reptiles.
What is the evolutionary link between aquatic and land plants?
Aquatic plants evolved into early land plants around 450 million years ago. The transition from water to land required adaptations such as developing structural support to withstand gravity, mechanisms for water retention, and strategies for reproduction in a drier environment. This transition allowed plants to colonize terrestrial habitats and diversify.
Why did whales return to the sea?
Whales returned to the sea from land because they evolved to adapt to the aquatic environment, where they found more food and less competition for resources.
Do whales have vestigial legs?
No, whales do not have vestigial legs. They evolved from land-dwelling mammals that had legs, but over time, their legs became adapted into flippers for swimming.
How might plate tectonics have influenced the evolution of whales and dolphins from land mammals?
Plate tectonics could have influenced the evolution of whales and dolphins by creating new habitats and changing ocean environments, which may have led to the adaptation of land mammals to aquatic life over time.
Why do beached whales need water poured over them?
Whales need the water. In the the water, whales are weightless. On land, whales weigh tons. If a whale is on land too long, they are crushed by their own weight. beached whales need water poured over them because they live in the ocean, so they are always wet, but when beached, their skin will start to dry out, which can kill them
How much time do whales spend in water?
Except for a few seconds when leaping into the air, whales spend ALL of their time in the water. They cannot move on land.
Do fin whales live in the tundra?
No. Whales are aquatic, meaning they live in water, preferably oceans. And tundra is land. Basically a cold prarie.
Do killer whales live in the ocean because they get oxygen from water?
killer whales are mammals but they can not live on land beacause they are to big and can not walk with flippers.
Can whales live in Australia?
they cant live on the land in australia, but in the water around it, sure.
Do whales live on water or land?
In the water. When beached, they cannot live long, even though they can breathe air.
What is the function of a whales forelimb?
Although it is a vestigial remnant from when whales were land mammals, now it is used to provide some help in steering. Whales have also been observed to 'slap' the water with them.
Can a tsunami carry large sealife towards land - ie sharks or whales?
yes they are in the water afterall
Do all mammal live on land?
Whales and dolphins are mammals and they live in the water so no, not all mammals live on land.
Could Humpback Whales walk on land?
No, they have flippers for moving through water, not the strong legs they would need to support their great weight on land.
What is a land animal that breeds in water?
If an animal is classed as a land animal in water, it mean they can either be on dry land or in water e.g. Frog There are also mammals which can live in water, such as whales and dolphins
ARE WHALES VEGTARIANS?
No they are carnivores. They will eat birds, fish, seals, and any land animal that gets to close to the water
