Why is embryology a good indicator of evolution?

Explanation:

Embryology is one of the vital branches of biological studies that aims to understand the growth and development of species before they are born. Investigating how an individual animal grows and develops before birth can shed light on its evolution and we can see how other species are related to the species in question.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
