SIZIF [17.4K]

Answer:

Likewise, competition for food among deep-water fish that eat the same types of food will .

Explanation:

Natural selection will condemn all deep-sea fish to the same environment that conditions them, those that cannot develop gills will be exposed to extinction, this refers to the theory of the evolution of the fittest by Charles Darwin.

Darwin studied actual birds on the Galapagos Islands instead of using a simulation, as you did in this lab. Studying natural sel
Elza [17]
Darwin lived in a time where natural selection was a strange theory among scientists and researchers. This was especially true when other researcher Lamarck argued that organisms passed on helpful traits to their offspring, that they magically could form a new trait to adapt to their environment and then pass it onto their offspring. For example, if a giraffe was too short to reach food, it would grow a larger neck in its lifetime and then pass that trait onto its offspring. Darwin argued that, through the process of survival of the fittest, that short giraffe would die off and never receive the chance to pass on its shortness to future populations. Thus, taller giraffes would survive— they can reach food, shorter giraffes can’t— and the short genes would disappear. The fact that Darwin was introducing a new theory that nobody was used to at the time was peculiar, so he had few people on his side until long after his observations.
Another problem Darwin had was the lack of technology. To travel, Darwin would have to use boats to reach far away places, and of course, this took time.
The final problem Darwin had was the extra time it took for evolution, a process that can take up to millions of years. Evolution didn’t occur over night— it took time for Darwin to conduct experiments, observe, conduct them again, come to a conclusion, and so on.
Hope this helped a little!

How does dispersal help different species? dispersal helps different species to increase their range of places, thereby helping
icang [17]

Dispersal helps different species to increase their range of places, thereby helping to increase their population size in different regions. Dispersal also helps to avoid crowding of diseases of a single location as species move to different locations.

<h3>What is dispersal?</h3>
  • Dispersal is the act of distributing things over a large area. It is when the individuals or seeds move from one site to their growing site.
  • Dispersal can be active (move by oneself) or passive (require dispersers).
  • Seed dispersal is the mechanism of transport of plant seeds to new sites for germination and the establishment of new individuals and colonies.
  • This depends upon the effectiveness of the seed dispersers.
  • Seed dispersal occurs by wind, water, animals, bats, explosions or gravity of the earth.
  • Dispersal of seeds is very important for the survival of plant species.
  • If the plants of same type grow too closely, they have to compete with each other for light, water and nutrients from the soil.
  • Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.
