Question

The more closely related two organisms are, the longer they will look alike during stages of early development prior to birth. This describes which piece of evidence for evolution?
a)Analogous structures
b)Vestigial structures
c)Embryology
d)Homologous structures

Which concept is a part of Lamarck's Theory of Evolution?

Organisms must struggle for existence


Organisms have more offspring than can survive


Traits can be modified, become stronger, and be passed on, while traits that are not used will disappear


Traits that are best suited to an environment will help organisms survive (survival of the fittest)

While making careful observations at the Galapagos Islands, Darwin noticed that each island had its own species of finch with different beaks. He later concluded that the species evolved by natural selection based on what they eat. What does the selecting of beaks in natural selection?

The individuals


The environment


The reproduction


The variations

Answer 1

Answer:

C,

Traits that are best suited to an environment will help organisms survive (survival of the fittest),

The variations

Explanation:

Embryology is the branch of biology and medicine concerned with the study of embryos and their development.

He states "Survival of the fittest "many times in his theory of evolution

Beaks are the best adapted (fittest) to the available food have the best chance of surviving (not starving to death) and of having descendants

Therefor having variation!

Hope this helps!
