The study of human biology within the framework of human evolution can be said to be the domain of?
psysical biologal anthropoly
when a computer is designed that will be able to design a computer more advanced than itself then we will have crossed the line and computer evolution will be quicker than our own
Explain why you feel a draft when someone leaves the door open on a cold night?
because cold air gets in
Which body parts are leftover in evolution and are no longer used?
It is a mistake to think of vestigial pieces of anatomy as pieces that are 'no longer used'. Evolution often adapts organs for new purposes, so there's no reason why any evolutionary leftover should sit around doing nothing.
That having been said, there are a few things that, while they do have *some* use, we could do without very well. Examples include tonsils, the appendix, floating ribs, wisdom teeth.
If human evolution is true why isn't it still going on?
It is; evolution occurs on a timescale so long that nobody will ever notice until a comparison is made with, say, the 10-thousandth generation onward; then you might see something. It is being affected by the way life is lived now, though; people who would otherwise not survive are cared for and supported well past the time when they would have died, and so the species progessively weakens overall.
The fact that mankind is caring for and supporting the people that would not survive without, is part of our evolution too. Species do what they must do to survive, and behaviour is subject to evolution as much as fysical features.
I understand that, but I'm saying as to why don't we see cave men any more or monkey looking people? Monkys are still around, why not the other species of the evolution?
How do you explain evolution as gently as possible to a religious fundamentalist?
The best way is to back up your story. I have had to go through this many times. It is also important to accept that God is a possibility (even though it isn't, haha). Say ways in which they are correct but then make your rebutle seem possible when considering gods existence.
lemarck ideas of evolution are known as the inheritance of acquire characteristic what was incorrect about his theory of how organisms evole
Of common ancestry, though ontogeny does not recapitulate phylogeny, ontogeny, development, can create phylogeny.
Evolution is concidered to be a?
Evolution is a scientific theory. A theory is consistent with all known laws of physics and satisfactorily explains all confirmed observations.
Select the item that supports the FACT that evolution continues today?
Evolution is a continuous and continuing process. DNA is the driver of evolution/driver of phenotypic change. Since DNA and the genome brought about the evolutionary change of biological form from prokaryote to eukaryote, from sarcopterygiian fish to amphibian and from australopithecine to hominid, it most certainly shall continue unabated today. Natural selection will sift out phenotypes incompatible with the environment, but the ultimate driver of evolution is DNA and genes and allele frequencies.
Natural selection can lead to the formation of a new species which is called?
The development of a new species through evolution is called speciation.
How has the early stages of development in embryos evidence of evolution?
stoned monkeys rule the world
Punctuated equilibrium interprets speciation as occurring how?
Rapidly in the development of new,beneficial traits, followed by very long periods of little change
This is known as convergent evolution.
An easy way to remember this is that they are converging....
which I tend to link to becoming the same.
To me this automatically states that they were different organisms to begin with. :)
How does the range of phenotype differ between single-gene traits and polygenic traits?
Single gene traits are either one type or another,for example everyone is either (ABO System) group A,B AB or O with no intermediates - this shows discontinuous variation.
In polgyenic traits, continuous variation is shown and there is a range with no discrete categories - height
Darwins theory of evolution did not contain the concept that?
Genetic variations are produced by mutations and sexual recombination
Natural selection leads to changes in both the physical appearance and what of a species?
And changes in allele frequency of populations; genes in genomes.
Also in the behavioral repertoire of species.
What is adaptation and evolution?
"adapted" means modified or changed or adjusted to make more suitable.
Example.
The man adapted a lawnmower engine to use to power his go-cart.
What is the name of your oldest common ancestor?
We evolved about 500 million years ago from fish that evolved to anphibians then mammals then we evolved to primates
Meiosis aids in evolution because it does what?
Meiosis is when the male gene and the female gene combine chromosomes to make a child or offspring.
This increases the diversity of genes in an individual, and allows that diversity to spread through the population, thus effecting evolution.
