    1. successful in life, they will generally go on multiplying in number as well as diverging in character

      This remind me of how mammals came to be, not just mammals, but the other classes that led to mammals

    2. largeness of area

      could this be because there is a greater capacity to hold them? For a time they might not struggle as much because variations might help partition niches

    3. dividuals presenting mutual and slightly favourable deviations of structure

      This can almost become a dependence though and wouldn't one say that would be bad? Because if the bees were to be wiped out then wouldn't the flowers be too? Or would they adapt, and other varieties become more dominant?

    4. infinitely better adapted

      This is such a great question!! Would any domesticated species survive in Nature? Probably not, but there could be exceptions

    5. , and this would manifestly be favourable to natural selection, by giving a better chance of profitable variations occurring

      By having more variation in a gene pool Natural Selection has more to act on and greater chances of species survival

    1. A large number of eggs is of some importance to those species,

      could this be reference r (more offspring to increases the chances of having ones that survive) vs k selected species,

    2. thousands are annually slaughtered for food

      they are also plagued by disease on occasion, and their health is compromised so much because of their close quarters and diets (not all agr. industries treat them like this, but it's disgusting the way some do)

    3. beautiful adaptations

      These two words just called out because it truly is amazing at the grandeur of forms that life has taken, reminds me of the Bryson reading on how everything that makes us up doesn't really care or even know that we exist but still works towards it

    1. the species of that genus present a number of varieties, that is of incipient species, beyond the average

      What's crazy is that now we can get an idea of how many varieties there can be, or what the varieties are through genetics

    2. inherit those advantages

      I forgot the actual phrase but this reminds of how present organisms have evolved with characters that were necessary for the the past, whether they serve the present well or not has to do with a bunch of factors - something of that sort it was from Diversity of life

    3. Mr. Babington gives 251 species, whereas Mr. Bentham gives only 112,—a difference of 139 doubtful forms!

      I wonder, is there a place where you can look and see if what constitutes a species and a "variety"? It seems very subjective.

    4. finding variability in important characters

      Even with important characters like organs, we might all have a similar "code", but it doesn't mean we all express it the same way.

    5. considerable deviation of structure in one part, either injurious to or not useful to the species, and not generally propagated.

      Whether it be sexual selection or survival of the fittest (or other hypotheses) that makes it that way
