The concepts of analogy and homology are probably easier to exemplify than to define. When different species are structurally compared, certain features can be described as either analogous or homologous. For example, flight requires certain rigid aeronautical principles of design, yet birds, bats, and insects have all conquered the air. The wings of all three types of animals derive from functions. In this case, the light organs of creatures can be said to be analogous. In contrast, features that arise from the same structures in the embryo but are used in different functions are said to be homologous. The pectoral fins of a fish, the wings of a bird and the forelimbs of a mammal are all homologous structures. They are genetically related in the sense that both the forelimb and the wing evolved from the fin.
According to the information , which of the following would most probably be considered analogous?

After help, we can use object + infinitive (with or without to).
| Can you help me (to) find my ring? (NOT | |
| Thank you so much for helping us (to) repair the car. | |
| Our main task is to help the company (to) become profitable. |
Help can also be followed directly by an infinitive without an object.
| Would you like to help pack? |
If you say that you cannot/can’t help doing something (especially in British English), you mean that you can’t stop yourself, even if you don’t want to do it.
| She’s a selfish woman, but somehow you can’t help liking her. | |
| Excuse me – I couldn’t help overhearing what you said. | |
| Sorry I broke the cup – I couldn’t help it. |
Can’t help can be followed by but + infinitive (without to), with the same meaning as can’t help verb + ing. This is common in American English.
