Synthetic chromosomes that damage yeast's evolutionary fitness
or fail to produce viable yeast may teach researchers how chromosomes evolved and give clues about the minimal requirements for eukaryotic life, he says.
We now know that "altruistic" helping can actually increase evolutionary fitness
in various ways - people might preferentially help their relatives, with whom they share genes, or they might target their helping toward others who are likely to reciprocate in the future.
Somehow you have the impression that there is some reality attached to it, but the actual mathematical description of any evolutionary process shows that evolutionary fitness
is an unnecessary concept.
Third, Murray came to insist that the Kimuran-style Malthusian Parameter is the only correct measure of evolutionary fitness
and other fitness measures, like net reproductive rate ([R.
In a paper published in the November 8 issue of the journal Current Biology, they conclude that not only do bacteria age, but that their ability to age allows bacteria to improve the evolutionary fitness
of their population by diversifying their reproductive investment between older and more youthful daughters.
It's really important for females to have the best male sperm to fertilise her eggs so if she can't choose before copulation then having a mechanism to choose after copulation could really increase her evolutionary fitness
," the BBC quoted Dr Rebecca Dean from Oxford University, who carried out the study, as saying.
A warm-up session was also held by Laura and David Venus of Whickham-based Evolutionary Fitness
Students will gain an understanding of how different methods of pathogen reproduction can greatly affect the evolutionary fitness
of a disease.
After developing a general tripartite argument against any historical defense of traditional institutions, the paper demonstrates its usefulness against three influential versions--the arguments from accumulated wisdom (Edmund Burke), evolutionary fitness
(Friedrich Hayek), and cultural identity (Lee Harris).
For example, Witham uncritically accepts the exhausted accusations that the Darwinian notion of evolutionary fitness
rests on a "fatal tautology," and that adaptationist theorizing is an ad hoc method for explaining everything and, thus, nothing at all.
You won't realise it, but when choosing a partner you're actually assessing their evolutionary fitness
and deciding whether he's the right man to father your children.
In choosing a partner we are subconsciously assessing their evolutionary fitness
to be a mother of children or father provider and protector, " Dr George Forster, scientific adviser to the think tank, said.
