When Darwin formulated the theory of evolution through THE PINZONES , he used changes he saw in the OTHER SPECIES OF THE GALAPAGOS ISLANDS to support his assertions. However, there are other pieces of evidence that demonstrate the occurrence of evolution in living things.

Explanation:

Charles Darwin analyzed the evolution of life or living beings through a species of birds that are called finches, also to reinforce this theory he analyzed other species on the Galapagos Island where these finches were, and noted that the turtles were from larger and the rest of the species also presented some differences, this is how their theory reinforces and drives it, indicating that the one that survives is the most suitable for that particular environment.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
