human ancestors- carnivore or herbivore ?

[Leison]

we have vestigial vermiform appendix and canines as well.today we are omnivorous but what was our feeding habit in the beginning?carnivore or herbivore ?

 

vermiform appendix shows we were once herbivore.

i think human started to eat plants ie crops after learning to farm (they maybe eating fruits before) and before learning the farming, they were carnivore.

 

 

++ if human ancestors were either carnivorous or herbivorous and now we've evolved to become omnivorous then " can the present herbivorous/ carnivorous turn into omnivorous in future?"

 

need help from specialists..

I don't see why not, if the evolution permits. If the conditions for survival favor carnivorous behavior, guess what, carnivores will persist.

Mainly herbivore, but a meat snack was there as well.

Wrong. You got to go back much much further back in time. Back before H.sapiens even existed.

 

 

Don't have time to explain it all in better detail. Will try to get to it tonight.

plez also specify whether carni/herbi/omni in the beginning

we descended from insect-eating small tree-dwelling animals called

Tree Shrews

 

there is an animal in the Philipines called the "Tupaia" which is still very much how it was back 60-100 million years ago in Dinosaur times and very much like our Ancestor.

 

We were small like squirrel and could run away from dinosaur and live in tree branches. always plenty of juicy insects to eat. it was a good life

 

when we were tree shrews we were the ancestors of Monkeys and Apes and Humans and Lemurs and Tarsirs and many many other kinds of animals.

 

so at that point our Ancestor was carnivore, but can better be called

insectivore

The problem is where do u want to put the beggining? The beggining is really back 4 Billion or so years ago and our ancestors were bacteria which broke down inorganic molecules and/or photosynthesised for energy. However I think the genus Homo has always been omnivorous' date=' however we are opportunistic and just ate whatever we needed/could for survival, this may have included scavenging, one theory for the development of tool use is we needed to break open scavenged bones to extract marrow.[/i']

Again a problem with how you phrase the question, when you state "we" you should say our ancestors, this was probably a herbivorous ancestor some time before the family "primates" was established, but I am not sure. Our appendix is vestigal from a time when our ancestors ate mainly grasses/leaves and extra bacteria were needed to break down cellulose. We have the same bacteria in our intestines but just in smaller quantities, these are what make you fart. I disagree with your other statement, we ate anything we could get our hands on.

Theres no reason why not, as long as the change of diet provides a more sucessful rate of survival, but things don't like to change if they don't have to.

could u plez explain when and how did the appendix develop.

i was talking abt the first Homo sapiens

[Sorcerer]

i was talking abt the first Homo [u']sapiens[/u]

 

They were omnivorous....... I stated this, opportunistic feeders, scavengers even. Sorry for misinterpreting. There is very little genetic/digestive physiology difference between us and the first homosapiens.

[dagaz]

Our closest living relatives, chimpanzees and bonobos, are both omnivorous as are many other primates.

[Leison]

was the appendix in vestigial form frm the beginning in Homo Sapiens ?

what about appendix of chimps?

[Sorcerer]

I think its actually a misnoma calling the appendix "vestigal" because it still plays a role today, it supplies an area for symbiotic bacteria to live in our guts, just beacuse it is smaller doesn't actually mean it has no function.... it just means that its function need not be as large as other animals where cellulose is a large part of the diet...... to answer I would say yes it was in "vestigal" form when our ancestors split in lingeage from the lineage of the genus pan, however as I just said vestigal is really a misnoma as cellulose will always be part of an omnivorous diet.
