The research stated that hominids walked on two feets, for at leat 2 million of years without their brain getting any larger.
Based on this, Stephen Jay Gould concludes that . The volume of the brain usually indicates the intellectual capacity of that organism.
Decomposers (like fungi, bacteria, some insects and snails)
Answer:
Larger islands that are large and close to the mainland are shos lower rate of extinction due to the fact that the species present have more space so there will be more resources available in comparison to smaller islands where limited space and limited resources available.
Extinction is greater on islands isolated due to the unlikelihood of immigration and as it is opposite to the island close to the mainland and competition is more in isolated islands.
The acacia is considered to be in an ecological niche. This is because it plays a certain role and position for species that are around it, and in this example the ants are the ones who interact with this tree. The tree then provides it with protection for it to survive its environment.
Answer:
c. wtih physically differing populations which can still successfully reproduce
Explanation:
Polytype is when a single species has many variations in its area of coverage, it is thought that they are distinct species, or when many varieties or breeds of the same species are produced, as in the Lobos, which is naturally already polypic, and many dog breeds are still bred within the subspecies Canis lupus familiaris. In other words, we can say that in a polytyp species, many individuals have very different physical characteristics, but are of the same species, so they can reproduce successfully.
