Yes, seals (along with their cousins the sea lions and walruses) evolved from the same branch of ‘dog-like carnivorans’ that also gave us bears, dogs, weasels and so on. Then the seals would return to their location of origin. Platypuses are only related to seals and otters in that they are all semi-aquatic mammals. Researchers believe that if the seals hadn’t been able to do so they would have become extinct millions of years ago.There is no doubt based on DNA and other scientific methods that seals are definitely related to the early land ancestors found. Once the pups have been born, there is a postpartum estrus period, and most females are mated within a few days of the last birth.
There are still some good theories about it, but not all of it can be identified at this time.
The ones that eat mostly fish specialize in oil-bearing species like eels, herrings, and anchovies because they swim in shoals and are easy to catch, and are good energy sources.
One Pinnipeds produce a variety of sounds, both in air and water. The most famous is a captive male harbor seal at the New England Aquarium named "Hoover" (1971–1985). Seals are divided into two families: the Phocidae, the earless or "true" seals (e.g., harbor or common seals), and the The pinnipeds include 34 species and 48 subspecies. These animals are not in any way closely related to whales, but they do have a surprisingly close link to modern bears, dogs, and weasels. Each elephant seal dive averages about 30 minutes in length, with only a couple of minutes between dives, and they have been seen maintaining that schedule for months on end.
Seals find prey by detecting prey vibrations using their whiskers (vibrissae). This was due to their natural environment being destroyed and a lack of food available.
Many of these early findings show that there were times when the seals didn’t have to evolve or adapt to any changes for a very long time. Bears belong to the Carnivoran suborder caniformia, which contains dogs, raccoons, mustelids (weasels, badgers, otters, and the like), skunks, and seals. Seals and sea lions are mostly fish-eaters, although most of the species also eat squid, mollusks, crustaceans, marine worms, sea birds, and other seals. They fact that they move on their stomachs doesn’t allow them to get anywhere fast on land. The Whole Bushel.
Seals are most closely related to modern day bears, weasels, skunks, and otters. It is believed that many of them followed the Gulf Stream in the water to reach Europe at that time. Others followed warm water currents into the Atlantic all the way down to the Caribbean. There is plenty of evidence to suggest they had to evolve in the early 1970’s as well. In financial ratios that use income statement sales values, "sales" refers to net sales, not gross sales. SEALS. Yet for it to be migration, it would have to be done on a yearly basis. Seals and walruses comprise a group of 33 aquatic mammal species with flippers known as pinnipeds, which is Latin for "feather-footed." Based on the scientific data we have, it is believed that seals evolved from land animals to what we know today. Female seals and sea lions live between 20 and 40 years. This is a very fascinating part of history that you may want to follow in depth.
In the U.S., the most well-known (and watched) concentrations of seals are in California and New England.The diet of seals is varied depending on the species, but most eat primarily fish and squid. This isn’t the process though as they have remained in those new locations since they moved there. As you learn more about early forms of seals you will come to appreciate their efforts of adaptation in order to survive as their natural environment around them forced them to evolve. Seals and sea lions are mostly fish-eaters, although most of the species also eat squid, mollusks, crustaceans, marine worms, sea birds, and other seals. In warm environments, the reverse is true. Biologists group pinnipeds into three families: true seals, or phocids; sea lions and fur seals, known as otarids; and walruses, or odobenids. However, over time their appendages changed into flippers so they could survive mainly in the bodies of water.
