The common ancestor between elephants and sirenians is Manatee.
A common ancestor for the Asian elephant (Elephas maximus) is believed to be a prehistoric species known as the "Elephas hysudricus," which lived around 2 to 3 million years ago. This ancestor is part of the Proboscidea order, which includes all elephants and their relatives. The evolutionary lineage of Asian elephants diverged from African elephants around 6 million years ago, leading to the distinct species we see today.
All dogs, the families and the like, have a common ancestor. Their kind is very different to cats, elephants and fruits.
Only in the sense that all animals share a common ancestor. Aside from that they are about as far apart ans two animals can get.
I would conclude that elephants and hyraxes share a common ancestor in evolutionary history, explaining the similarities in their DNA despite their vast differences in size and appearance. This suggests that they diverged from a shared ancestor relatively recently in evolutionary terms.
they are harbivores.
The common ancestor is the Hyracotherium
Homoplasy refers to similarities in traits between different species that are not inherited from a common ancestor, while homologous structures are traits that are inherited from a common ancestor and have similar functions.
Mammoths were a member of the elephant family. The closest living relatives of the mammoths are Asiatic elephants. They are related because they evolved from a common ancestor.
Two people who share the same great great grandparents are third cousins. To find a cousin relationship, find the common ancestor. If common ancestor is grandparents, they are 1st cousins. If common ancestor is great-grandparents, they are 2nd cousins. If common ancestor is great-great-grandparents, they are 3rd cousins.
You aren't. You do not share a common ancestor.
that they share a common ancestor
An 'ape' is any primate belonging to the superfamily Hominoidea, and this includes humans, so we 'are' apes, along with gorillas, chimpanzees and orangutans. All these species though have a common ancestor.
