Biology Quiz

Just taking a shot to see wether more biology-oriented minds are on this forum.

For kick-off a simple yet scientific one;
What is the today living ancestor of the homo erectus?

 

homosapians?

 

homo sapiens sapiens

 

Or, more simply, us.

 

Isnt H.Sapiens Sapiens a descendant of H.Erectus

Ancestor would probably be a one of the primates -- possibly some sort of lemur?

Tom

 

How is that for mis-reading a question! :roll:

Gorilla?
(I wanted to say orang outang, but wasn't sure how to spell it)

 

Asked the wrong question.
I meant descendant
(let that be a lesson to me, don't make up biology questions during chemistry class)
Anyway Quillin had the first correct answer.
For ancestor it would have been the chimpansee or gorilla I think, it would have been quite debatable.

 

hmm, i have to make a question a couple hours befor an exam. lets see how good this one is.

to qoute Darwin: "Survival of the fittest". what did he exactly mean with "fittest"?

 

best adapted to their current environment (i.e. fittest for purpose)

Tom

 

correct, next one is for you

BTW: small joke.
what kind of law did Darwins younger brother made?
"survival of the second most fittest" :lol:

okay, i'll get my bags

 

OK, think biologically in a military forum...

Why is brontosaurus no longer "official"?

Tom

 

??? okay, i don't understand the question
dino's not again. a couple mounths ago we had a sort of dino topic

 

Extinct species are part of biology (paleontology or something, is it?).

I don't know what you mean either, by the way, Tom.

 

It isn't official anymore because; they thought there were 2 different dinosaurs(can't remember their name), turned out the bones from the brontasaurus were actually the bones to the other.

Sorry to be confusing and/or vague.

 

Very good, CSP.

Brontosaurus has become Apatosaurus because two people discovered the species independantly and gave it different names. Because Apatosaurus was published first, brontosaurus is no longer an official name.

Sorry if the question was confusing!

Over to CSP

Tom

 

This bird, which resided in newfoundland , went extinct in the 19th century. What was its name ?(im sure this counts as a biology question. Frankly , I can not come up with anything else)

 

Great Auk ?


Tom

 

You are right.

 

OK -- pass on the next question. Quiz open to anyone

Tom

 

Without cutting it open there is 1 way to determine an octopus' sex.
How?
I'm refering to physical aspects, not behaviour.
