Parenting strategies vary greatly in the animal kingdom. One strategy is unequal parental investment, in which males contribute very little, if anything, to rearing the offspring. Identify the situations in which unequal parental investment will be favored.

OPTIONS:

-The fitness of offspring raised by one parent is high.

-Acquiring additional mates is relatively easy.

-Females give birth to multiple infants at once.

-Females are widely separated in an environment

-The fitness of offspring raised by one parent is high.

-Acquiring additional mates is relatively easy.

Explanation:

When the fitness of offspring raised by one parent is high, that is if the survival and fitness of an offspring is largely favored when cared for by one parent, this might result to unequal parental investment being favored, since the survival of the offspring is mostly determined by one of the parents. For example, if breast milk and warmth of a female animal is very paramount or the survival of an offspring, there is likely going to be an unequal parental investment, since most of the caring would come from the female.

Unequal parental investment can also be favored when having access to additional mates is relatively easy.For example, if a male animal species is surrounded by many females of the same species, mating with multiple mates become easy, and when this occurs, it is very unlikely that the male would contribute anything to raising any offspring of any particular female mate, as he would just simply find it easy to move along with another female.

from almost the creation of the first true maps of the earth, people started seeing how continents would be able to fit together.   in particular, people noticed that south america fits almost exactly into africa.

you should be aware that while world maps were around early in the 1600’s and better defined by the end of the 1700’s, those maps were not ‘public’ but were treated as state secrets.   and so it was not till much later that the broader ‘science’ community had access to good quality and accurate world maps.

get the whole story here…

it is now known that most of the major continental masses can be fit together in a jigsaw process.   in fact we now know that the continents were indeed once all joined together as one land mass – the supercontinent of pangaea.

if you look at most world maps you will ponder how this is evidence, as the continents really don’t appear to ‘fit’ together very well.   what you need to understand is that the vast majority of maps are drawn using a map projection that has the north and south poles (which are points) are a line the width of the map at the top and bottom.   this means that the map distorts the true shape of the earth’s land and oceans as you love closer to the poles.     some other map projections distort less, but have the map shape looking like segments of an orange.   see here for a range of map projections.   check out the way greenland changes size in each!

what is more remarkable, is the next piece of evidence when added to the shape of continents.

location of mountains and fossils

what is remarkable, when you reassemble all the continents together, the ancient mountain ranges (many now eroded to their cores) and the location of rock types and fossils all match up.
