Scientists believe the Earth formed 4.6 billion years ago, the oceans were created 4.4 billion years ago and the first cells appeared on Earth 3.5 billion years ago. How do scientists know this? Obviously we can't go back in time to observe all of this. So what evidence do scientists have to know these events occured at these time periods?
The island of Madagascar is famous for its lemurs, flying foxes, and mongooses. But how they got to this isolated island has been a question that scientists have pondered for many years. Recent researchers believe that Animals Populated Madagascar by Rafting There. How did the wildlife on Madagascar become so unique? Where did the animals come from? And what evidence do we have that supports this idea?

It's possible that explorers came from various points around the world with animals native to their countries, which bred with animals native to the island of Madagascar. This has happened on previous occasions when European explorers first adventured into North and South America, bringing in European breeds and mixing them with the native American ones. Another possibility is that the species currently living in Madagascar evolved in order to adapt to their environment. Lemurs are in the primate family, so they might once have been monkeys or a similar species. Many species across the globe have adapted to their unique environments. The animals of Madagascar are no different.
ReplyDeleteThis can be possible because like many people have said it the world many years ago was one, together As well known as PANGEA. Animals could have migrated to this little island. Provably thats how animals use to look. Since we now see animal the way they are we find animals from Madagascar unique or different. Its like if some one had glasses for a couple of months then that person later takes them of, that person will look different but its the same person. This could have happen if the animals from the island have been isolated.
ReplyDeleteWe can find the age of fossils by carbon dating, so we know the relative time when the animal from a skeleton came from. The animals in Mdagascar probably came from mainland Africa, which we can see by comparing fossil records from Madagascar to those in mainland Africa, which are similiar. Thye are probably very uniques since once they migrated, they went through natural selection, altering their physical characteristics and appearance.
ReplyDeleteWhen the earth was first formed all of the contienets were connected. This means that when the land did seperate, certain organisms were carried a long with those parts of land that drifted away. This shows why there are traces of similar animals in the continental Africa.
ReplyDeleteAnimals on Madagascar could be so unique due to (the theory of) evolution. First, different animals were created by the process of evolution, similar to the hypothesis of humans evolved from monkeys. Now that, all these humans or animals on Madagascar are evolved; they developed different phenotypes. For example, a human could have blonde hair like how a bird has pink feathers, while another human has brown hair and a bird has blue feathers.
