Infinity of biology ​
PSYCHO15rus [73]

Answer:

Origin: L. Infinitas; pref. In- not – finis boundary, limit, end: cf. F. Infinite. See Finite.

1. Unlimited extent of time, space, or quantity; eternity; boundlessness; immensity. There can not be more infinities than one; for one of them would limit the other. (Sir W. Raleigh)

2. Unlimited capacity, energy, excellence, or knowledge; as, the infinity of god and his perfections.

3. Endless or indefinite number; great multitude; as an infinity of beauties.

4. (Science: mathematics) a quantity greater than any assignable quantity of the same kind.

Mathematically considered, infinity is always a limit of a variable quantity, resulting from a particular supposition made upon the varying element which enters it.

5. (Science: geometry) That part of a line, or of a plane, or of space, which is infinitely distant. In modern geometry, parallel lines or planes are sometimes treated as lines or planes meeting at infinity. Circle at infinity, an imaginary circle at infinity, through which, in geometry of three dimensions, every sphere is imagined to pass. Circular points at infinity. See Circular.

In the genetic drift analogy of a drunk man on a train platform, the width of the platform is analogous to what
konstantin123 [22]

The answer is the population size.  The chance has a role in determining whether a given individual survives and reproduces and the alleles in the offspring are a sample of those in the parents. it is the change in the frequency of an existing gene variant (allele) in a population due to random sampling of organisms. Genetic Drift or another term for allelic drift or the Sewall Wright effect.

How is HIV is a modern-day driving force for human evolution?
juin [17]

Answer:

Testing positive for HIV means a high chance of death and a good chance of lower reproduction rates. But some people are immune to HIV, which makes them more evolutionarily fit, likely to live longer, likely to reproduce more, which would increase the frequency of the immune allele in the population. Over time, this increase in frequency of the gene that causes immunity could spread across the human race and cause it to evolve.
